MediaInfo(Lib) 0.7 - Reading information about media files [Archive]

Zenitram

27th June 2005, 23:33

I develop MediaInfo, which is a tool to show technical information (container format, codec, width, heigth...) and tags (Title, Artist, Language...) about all kind of multimedia files. Main purpose is to have a library for third-parties, but there is a graphical interface too.

I wish have some beta testers with complex files, to "stress" the program just released.
http://mediainfo.sf.net
There are :
- A graphical interface
- A command line interface
- A DLL for programers (with C++, C#, J#, VB.nt, VB5, Delphi, ActiveX examples)

I already did some tests on :
Matroska, Avi, Wav, Ogg, Ogm, Mpg, Vob, Mp4, M4a, 3gp, M2v, mp3, Wma, Wmv, Mov, Rm, Rmvb, Ifo of DVD, Aac, Ac3, Dts, Monkey Audio, Ape, Flac, Au, Aiff.
I am working on H264.

Did I forget a container?

Good idea! It'll be useful. GSpot not support anything except *.avi. Cheers.

just tested some files of my collection:

first of all, is .swf (flash) supported? its not mentioned anywhere but mediainfo finds mpeg-audio streams in some of them (albeit with bitrate 0).. i'm not sure if those are really mpeg audio streams, but it could very well be so..

i guess "S-Mpeg 4 v3" should really be "MS-Mpeg 4 v3", right?

why is the mpeg container called "MPEG 1 Multiplexer" instead of simply "MPEG 1"? is this the official name?

"MPEG-4 Video" should maybe renamed to "MPEG-4 (A)SP" and "MPEG-4 AVC" to better differentiate the two variants

while "MPEG-4 Audio" is technically correct, i think it would be more helpfull for users if you would write "MPEG-4 Audio (AAC)" and maybe even "MPEG-4 Audio (HE-AAC)" too.

the codecs in this .mov here (http://download.theforce.net/theater/nonsw/grayson/Grayson_web_large.zip) are not recognised at all. according to mplayer they should be "ima4" (IMA ADPCM) for audio and "SVQ3" (Sorensen Video 3) for the video track.

this movie here (http://www.kollektiv-kaffeemaschine.com/media/nebenderarbeitQT.mov) has exactly the same codecs, but this time "ima4" is detected as a second video track instead of the audio track.

i would appreciate it if the actual FOURCC would be displayed somewhere in conjunction with your "translated" description

whenever there is no audio or video track in a container, the codec name is displayed in the format-column too instead of the real container name, which is very confusing (at least for me).

i have another .mov on my hd (sorry, no link) which isn't recognised at all too. codecs are "Sorensen Video 3" and uncompressed pcm audio (FOURCC: "twos"). i can upload it somewhere if you want.

that's it for now, more to come later =)

Thank you for your tests.

just tested some files of my collection:

No support of SWF.
My MPEG audio parser has difficulties to detect false MPEG Audio, because MPEG Audio "magic value" is only 12 bits :(
I will put more tests about coherancy of value (bitrate 0 and so on...)

i guess "S-Mpeg 4 v3" should really be "MS-Mpeg 4 v3", right?

Writing error, will be corrected ;-)

why is the mpeg container called "MPEG 1 Multiplexer" instead of simply "MPEG 1"? is this the official name?

MPEG is a group (Movie Picture Expert Group), who released a lot of standarts, with MPEG 1 Video, MPEG 1 Audio, MPEG1 Multiplexer and so on...
I would like to differenciate them.

"MPEG-4 Video" should maybe renamed to "MPEG-4 (A)SP" and "MPEG-4 AVC" to better differentiate the two variants
while "MPEG-4 Audio" is technically correct, i think it would be more helpfull for users if you would write "MPEG-4 Audio (AAC)" and maybe even "MPEG-4 Audio (HE-AAC)" too.

I will look at what I can do. Not sur to be able to always differenciate them.

the codecs in this .mov here (http://download.theforce.net/theater/nonsw/grayson/Grayson_web_large.zip) are not recognised at all. according to mplayer they should be "ima4" (IMA ADPCM) for audio and "SVQ3" (Sorensen Video 3) for the video track.

this movie here (http://www.kollektiv-kaffeemaschine.com/media/nebenderarbeitQT.mov) has exactly the same codecs, but this time "ima4" is detected as a second video track instead of the audio track.

I will download theses files

i would appreciate it if the actual FOURCC would be displayed somewhere in conjunction with your "translated" description

in the menu : Debug-->Advanced mode.
Or : you can edit preferences (for "sheet" view, or HTML...), and add "%Codec%" (instead of "%Codec_String%)

whenever there is no audio or video track in a container, the codec name is displayed in the format-column too instead of the real container name, which is very confusing (at least for me).

I don't have files with a container but without streams, could you send me one?

i have another .mov on my hd (sorry, no link) which isn't recognised at all too. codecs are "Sorensen Video 3" and uncompressed pcm audio (FOURCC: "twos"). i can upload it somewhere if you want.

Interested to have it.

that's it for now, more to come later =)
I am waiting for it :)

MPEG is a group (Movie Picture Expert Group), who released a lot of standarts, with MPEG 1 Video, MPEG 1 Audio, MPEG1 Multiplexer and so on...
I would like to differenciate them.
yeah, i know. but then the really correct name would be "MPEG-1 Systems Multiplex". also the codecs are correctly written with a dash before the number, f.e. "MPEG-1 Audio" or "MPEG-2 Video" instead of "MPEG Audio 1" or "MPEG Video 2".

What about MPEG transport streams? are they supported? i tried a sample but mediainfo found only the video stream and no audio stream.. (http://www.nextcomwireless.com/R5000/samples.htm)

if they are not supported, the correct description for the MPEG-2 container would be "MPEG-2 Program Stream", because "MPEG-2 Systems Multiplex" describes both, program streams and transport streams.

I don't have files with a container but without streams, could you send me one?
i didn't mean a container without any stream (would be quite useless), just one without an audio stream but with a video stream or the inverse.
but i just saw that this isn't a real problem, i was only confused because you called MPEG Elementary Streams "MPEG Video 1" etc. but you are probably correct, an elementary stream really doesn't have a container/format, its just the audio/video stream.

Interested to have it.
i put it on my ftp. also i found some other samples which are detected incorrect. you can find them all in "video-samples" on my ftp. i will send you the address per pm.

OK, I will change for this.
But : what should I write for "MPEG Audio 2.5 (some MP3 have this, extended version of MPEG-2 Audio...)? MPEG-2.5 Audio?
but : "MPEG-1 Systems Multiplex" is long :(. I think I will change it in MPEG-x PS, and MPEG-x TS (see below for TS)

What about MPEG transport streams? are they supported?

TS? Not yet, because I didn't find documentation on this (which bit for what), :(

if they are not supported, the correct description for the MPEG-2 container would be "MPEG-2 Program Stream", because "MPEG-2 Systems Multiplex" describes both, program streams and transport streams.

if you know MPEG system, could you tel me where PS is used (DVD, and?), and where TS is used?
I have difficulties to understand all in the MPEG standarts, they are a little difficult with a lot of standarts :)

OK, I understand more what you said.
And as you said, Video ES or Audio ES (=MP3 or raw AAC) doesn't have a container, so I use the ES name in place of the container name, and I think to not change this.

Thank you for your analysis.

OK, I will change for this.
But : what should I write for "MPEG Audio 2.5 (some MP3 have this, extended version of MPEG-2 Audio...)? MPEG-2.5 Audio?
yes, looks good to me. or maybe just leave it at MPEG-2, and describe the .5 part somewhere in the advanced mode text. MPEG-2.5 is a proprietary extension by FHG that only allows for some lower sample frequencies and bitrates, but it's not officially endorsed by the MPEG committee in any way.

but : "MPEG-1 Systems Multiplex" is long :(. I think I will change it in MPEG-x PS, and MPEG-x TS (see below for TS)
yes, that is ok too.

TS? Not yet, because I didn't find documentation on this (which bit for what), :(
you can find the last draft on this page: http://www.le-hacker.org/dvd.html, this should be a good starting point.

if you know MPEG system, could you tel me where PS is used (DVD, and?), and where TS is used?
afaik (but i'm not an expert) PS are officially used on VCD, SVCD and all variants thereof. VOBs on DVD contain several ES as well as other stuff for menu's etc.

TS are mainly used for digital broadcasting (DVB/ATSC/ISDB).

Hi Zenitram,

First of all, many thanks for this tool. It's very nice....;) I'll use mediainfo.dll in the next YAMB release. (not finished yet but I'll release it very soon). I'd like to suggest you to use some GPAC code for mp4 files. It's up to date comparing to the mpeg4ip libraries...(h264, ,avc supports...) Hope this help.

@Zenitram:

Could you post how can I call mediainfo.dll from VB6 files please.
Just for 1 file (not several media files).
If you can, post examples to obtain width, height, fps, bitrate, etc.
Thanks.

Hmm... could it be that the feature matrix (http://mediainfo.sourceforge.net/formats.html) is incomplete? Looking at the screenshots I see "play length" but that doesn't seem to be listed in the matrix. For me getting the length of a file (audio or video) as well as number of frames (in case of video) are the features I'm most interested in.

Thanks for your replies...
I'd like to suggest you to use some GPAC code for mp4 files.I should.
But this is actually hard to understand GPAC interface (mainly for tags).
I use mp4ff for codecs, and mp4v2 for tags.
I know how to do for codecs with GPAC, but I don't know how to do for tags.
I will work on it, but some difficulties... ;-)

Could you post how can I call mediainfo.dll from VB6 files please.
There is an VB5 (works on VB6 too) example with the DLL package, in the "Contrib" Directory.
Not exactly what you want, but you should easily understand how to do

Hmm... could it be that the feature matrix (http://mediainfo.sourceforge.net/formats.html) is incomplete?
little outdated

Looking at the screenshots I see "play length" but that doesn't seem to be listed in the matrix.
Duration is the same as "Play length", I changed the name in MediaInfo, but not in the matrix :(
For me getting the length of a file (audio or video) as well as number of frames (in case of video) are the features I'm most interested in.MediaInfo_Option(NULL, "Info_Parameters") to have all available parameters.
MediaInfo_Get(Handle, Stream_General, 0, "PlayTime", Info_Text, Info_Name) to have the length in millisecond (or "PlayTime_String1" or 2 or 3 to have formated text ("?h ?mn ?s"...)
MediaInfo_Get(Handle, Stream_Video, 0, "FrameCount", Info_Text, Info_Name) to have number of Frames (or PlayTime*FrameRate if you prefer...)
Track information seems to be missing for MKV... could be cool to have it :)The complete work on MKV is not done yet, this will come soon!

It's not really the news for your average users, but since I find the library useful I guess I could make an exception.

I am a little lost with MPEG4 libraries, I didn't find yet the perfect library for my needs :(

bond

3rd July 2005, 14:59

tags are a special issue in mp4 because there is an official tagging standard for mp4, but the power of itunes (which uses a private tagging way) lead to that people use only the itunestagging
and as always private stuff leads to a mess...

i would say there are two good mp4 libs available: the one from mpeg4ip and the one from gpac

mpeg4ip tags in the itunesway, gpac i think in the official mpeg way (but i have to admit i never really tested it so i dunno much about it)

I downloaded the zip package of this just to take a look and I must admit I was not very impressed with the way you 'shell' associated everything from within your program!

You should leave that to an installer!

Just took me half an hour hacking my registry to remove all the crap! :mad:
I don't understand :
- you downloaded the Installer file : all registry keys are deleted with uninstall
- you downloaded the ZIP file : how could I know you want to delete MediaInfo??? and this is a "one click" thing to suppress registry keys without uninstaller : uncheck Options, advanced, Shell explorer.

If you have an idea to do it with a better behaviour, I am interested... At this time, there *IS* an installer/uninstaller, and for people who want ZIP files, there is a ZIP file with the possibility to uncheck the shell explorer...
I don't plan to suppress the ZIP files, because some people want it.

And I don't think there is a better solution, a lot of software have the same problem if associations when shipped in a ZIP file...

pulldown detection will be incorpored? :D
Do yo uspeak of this (http://www.zerocut.com/tech/pulldown.html)?
1/ MediaInfo works on video track information, not frame per frame : I don't plan do say where is "A" frames. the only thing I plan to do in video frames is to know if video is compatible with DivX player (B-frames...), because his is a video track information, not only for some frames. So I don"t see what you would know about pulldown in MediaInfo.
2/ I am european, so I don't need pulldown (joke :D )

Can you library tell me if an audio file is variable or constant bitrate?

Zenitram

8th July 2005, 18:40

Can you library tell me if an audio file is variable or constant bitrate?
Yes, when I can say it. (with GUI : select advanced mode, and there will sometimes be a "BitRate Mode" tag)
This is the case of MP3.
But for other audio formats, the format tells you if this is VBR or CBR (OGg is VBR, AC3 is CBR...)
The problem I didn't succeed to resolved is MP3 in AVI : I can't say VBR or CBR :(
Which format to you wish?

Doom9

9th July 2005, 03:27

I'd like to give your lib (the dll) an mp3 and have it tell me if it's vbr or cbr. Right now the user has to enter the audio type manually. That is all outside of an AVI. But in order to mux an MP3 into an AVI, knowing if it's CBR or VBR is crucial because the overhead changes significantly.

Zenitram

9th July 2005, 17:45

Doom9> So : Yes, you (will) be able to do this.
Why "will"? Because, I took a look in the source code, I saw I detect VBR or CBR to calculate bitrate (I need to know if this is a VBR file too), but I forgot to set the VBR tag on for external programs :(
In next version for this.
But : even if I dream you use MediaInfo.dll (because thanks to your homepage, I have at this time twice more people on my homepage, maybe the same with the DLL :) ), I don't understand you : there is simpler way to detect VBR in a MP3 file, because everybody use "xing" VBR header (but xing website is now offline :(, so : no specifications) (and I use only this method to detect VBR), and this is some line of code only, so no need of a 600 KB DLL to use only 20 lines of code.
You can take a look here (http://cvs.sourceforge.net/viewcvs.py/mediainfo/MediaInfoLib/Source/MediaInfo/File_Mpega.cpp?annotate=1.27) , line 540 to write your own parser.

Doom9

9th July 2005, 18:04

well.. if I start using the lib then for the follwowing purposes:

detec if an mp3 is vbr or cbr
get the length of ac3/mp3/mp2/wav input
get the length, number of frames and framerate of an AviSynth file.

I'm not sure, can you handle the last one? I currently use AVIFile for the last one and have no solution for the other two.

Zenitram

9th July 2005, 18:56

detec if an mp3 is vbr or cbr
get the length of ac3/mp3/mp2/wav inputWill be able in the next version (while speaking with you, I took a look to your requests, seems I forgot some things, so there is not always information, even if it is easy to have it, MediaInfo.dll is young :(
get the length, number of frames and framerate of an AviSynth file..Not sure to understand : in my mind, AviSynth is only a script file (AVS), with not real video or audio in it. and I work only on real video or audio files. And I try do not have Win32 dependancies (so : no AVIFile for me :) ). Maybe later I will inspect AVS file, to detect original file (but if this is a D2V file, I need to parse it too to have source files :( ), but don't hope it soon.
So : I will work on having length for AC3/mp3/wav (and VBR) in the next version, it is easy.

Doom9

9th July 2005, 19:06

Not sure to understand : in my mind, AviSynth is only a script file (AVS), with not real video or audio in it. and I work only on real video or audio files.hmm.. then I guess we have a problem. It is possible to read those things without any platform dependencies though.. x264 and mencoder can handle AviSynth input.

hmm.. then I guess we have a problem. It is possible to read those things without any platform dependencies though.. x264 and mencoder can handle AviSynth input.
Ah? OK, you speak about avifile library, not AVIFile Win32 API, sorry.
Will take a look in it to see what I can do.

Doom9

9th July 2005, 19:46

no I meant I AM using the W32 AVIFile API but I'd like to get away from it. I guess I'll always rely on it for video preview, but at least for getting the properties of the source something else could come in handy. The problem some of the MeGUI users have is that they don't have the codecs to play YV12 installed but tested their script in other apps that do not require a YV12 decoder (or use a DShow one), and so they have a basically working AviSynth script that might even be encodable, but due to AVIFile requiring the YV12 decoder they cannot start without installing that codec first.

Either way I'd understand if you won't support AviSynth because it's not really a media file.

Zenitram

10th July 2005, 01:41

Doom9> Seems to not be too difficult, if you wish only to support AVS with .AVI in it, or D2V in it (if D2V has VOB in it for example), because I can write basic AVS and D2V parsers to extract original filenames. Is it why you wish? if yes, OK, I will do it because this is not opposite of MediaInfo philosophy.
And : do you know AVS with other than D2V or VOB? If yes, I am interested to have examples. (maybe in private)

Doom9

10th July 2005, 01:49

Well, I suppose the most common use case is an AviSynth script with a d2vsource in it.

Other options are AviSource, WavSource, DirectShowSource and AC3Source. I'm not sure how mencoder and co read AVS sources.. definitely not through AVIFile but most Windows Applications use AVIFile as AviSynth appears to be just another VfW decodeable format. I think parsing the script and looking what's in there could provide to be dangerous.. actually rendering sounds more promising.. for the specifics I'd check x264 or mencoder source code (probably the latter since it's smaller).

Zenitram

25th July 2005, 00:17

At this time (v0.7.0.1), this piece of information is not implemented for MKV (it is for OGM), it will be soon for MKV.
You can work with OGM, this will be the same way to get info for MKV ;-)

PS : you can monitor DLL release (http://sourceforge.net/project/filemodule_monitor.php?filemodule_id=90614) to be informed imediatly when I release a new version

@Zenitram

Is it possible for a track (video, audio, sub) in MKV (MP4) to know which track number it is in the source file?

ex:
MP4
1: general
2: general
3: video
4: audio

MKV
1: video
2: audio
3: audio
4: sub
5: sub

Could be very very usefull to get infos about a file and build a command line to extract each tracks to separate files.

Thanks!

[edit]

Also, in the doc you only show the first 2-3 params for function Parameters. Where can I have a full list?

Is it possible for a track (video, audio, sub) in MKV (MP4) to know which track number it is in the source file?
This is not really possible, because libraries I use (mp4ff and matroskalib) doesn't give this kind of info.
MKV give an unique ID ("KaxTrackNumber" in the spec), you can retrieve it with "ID" parameter (but need more tests.

Could be very very usefull to get infos about a file and build a command line to extract each tracks to separate files.
You are welcome to help me programming ;-)
Now, I am very occupied with GCC under Linux compilation, add more tags support, support of new formats (last quicktime version...), debugging, and I have not the time to do this...

Also, in the doc you only show the first 2-3 params for function Parameters. Where can I have a full list?
http://mediainfo.sourceforge.net/fr/Support/SDK/More_Info#Capacities
(need to be more detaileld, but lack of time...)
What you need is MediaInfo::Option("Info_Parameters_CSV")

Note : I am late for a new version, but for subtitles in MKV 0.7.0.1 should have already implemented it ("Language" or "Language/String1" parameter)
At this time, 0.7 branch is very unstable, so I need time to stabilize this, be patient, it will be done...

@Sirber : DLL v0.7.0.2 is out, with more "language" support :
- "Language" for the Language in the container
- "Language/String" for a translation (in English)
- "Language/2" for ISO format (2 digits)

And for MKV (mainly, maybe others later) :
- "StreamID" for the track number of this kind
- "ID" for the track number it is in the source file
- "UniqueID" for the track Number specified as Unique Identifier of the track

To know all supported formats :
MediaInfo::Option("Info_Parameters")

Will try to correct other bugs now ;-)

History :
x #1323208 : Video Bitrate for OGM files with VBR audio was incorrect
+ Better detection and handling of DivX container
+ #1327902 : More meta data properties for RIFF files
x #1327468 : RIFF (AVI) files with not-padded (INFO) sub chunks can't be parsed
+ More "generic" tags added
x Some other minor bugs

iso639 : http://www.w3.org/WAI/ER/IG/ert/iso639.htm or http://www.loc.gov/standards/iso639-2/frenchlangn.html
In MediaInfo, I use for all containers the 2-character iso639-1 code.
If the container use the 3-character iso639-2 code (like matroska), I translate it in iso639-1 (if possible, 99.99999% of cases ;-) ).
The 2-character code of Japanese is "ja".
So, if you read a DVD or an AVI or a Matroska file, Japanese will always be "ja", not sometines "jpn" and sometimes "ja"!

At the moment mkvmerge does not support converting from VfW-mode AVC/h.264 tracks to native Matroska-mode AVC/h.264 tracks. You can, however, first import the video track into a MP4 file with e.g. 'MP4Box' (use Google). Then you can use mkvmerge and put the video into a Matroska file.

Even with the new version of mediainfo I'm still finding it's having problems reading my audio files correctly (un-muxed).

For instance, using megui and nero AAC to encode audio files from AC3 I tried two different settings: 'streaming' on VBR setting LC profile, and 'normal' on VBR setting LC profile.

Mediainfo detects both as such:

Audio #0
Codec : MPEG-1 Audio layer 3
Bit rate : 128 Kbps
Bit rate mode : CBR
Channel(s) : 2 channels
Channel coupling : Joint stereo
Sampling rate : 48 KHz

I was test encoding these through the besweet option and not avisynth. I haven't ruled out the possibility a a besweet/megui error however I've noticed other people have some similar issues with mediainfo incorrectly identifying media types.

Still a very useful tool and I hope it only gets better!

EDIT: I think this is a problem with megui and besweet. I just realized both are the same filesize and mpc detects both as 128kbit also. Sorry if this is unfounded.

If I understand well, Interleave is in "Delay/Video0" tag. this tag is the delay between the first Audio chunk and the Video.
edit: hmm, can interleave be calculated or is it something that's stored in the header of the container?
It is calculated in AVI (null bytes before the first chunk of AC3 for example)
It is from the header for MPEG-1/2 PS/TS (Presentation TimeStamp)

When feeding MediaInfo with elementary MPEG-4 Part 2 streams it would seem it's able to identify information such as: -

Aspect Ratio,
TV Standard,
Chroma,
Interlacement
Writing Library
http://img338.imageshack.us/img338/6889/mediainfowithcmpce3.png

But once the same elementary stream is muxed into the MP4 container (with MP4Box), much of the above mentioned information is lost and the "Aspect Ratio" information is incorrect: -

When accessing MP4 files is there any way of providing the same kind of data as the elementary streams?

When feeding MediaInfo with elementary MPEG-4 Part 2 streams it would seem it's able to identify information such as:
Currently I can read this kind of information in :
- Raw MPEG-4 Video stream
- MPEG-4 Video stream in AVI container.

Why? because this kind of info is only available when decoding the first frame of the stream, not in the container. I already connected the MPEG-4 Video parser with AVI parser, not others.

I found how to do for OGG, MKV an MP4 containers, I will integrate as soon as I have time to do it ;-).
For MP4 container, it is not so easy to integrate, but I think the next version will support it. But I need to finnish to write my own parser before (I used mpeg4ip library, but it does not like malformed .mp4 files...)

Hi,

I have a feature request:

Would it be possible to show the embedded Cover in the mp4-Kontainer? In the moment it´s realised that there is a cover - but not shown. :)

Zenitram

4th September 2006, 15:36

Would it be possible to show the embedded Cover in the mp4-Kontainer?
This is planned.
But not soon.
Why?
- The next version will have a lot better parser, I will be able to read 3 different means for tags (currently : I read only 1).
- I will be able to encode the Cover in the MediaInfo library easily.
- But the GUI is text-based only. I must adapt the GUI, whish is more complex.

So the cover will be availble for th library soon, but you must wait a moment for the cover in the GUI, sorry but I have not enough time to implement all in the next release. time, time...

The version of today is a proof of concept for MP4 parser, do not spread it, please.
All MPEG-4 Video attributes should be available for a MP4 file.

Of course more information depend on number of video/audio streams so I have to scan for them.

Depends on the container himself I'd say...For mp4 & mkv files, we can have metadata and/or tags first, if you're refering at the General Information pattern.

bog standard avi file (xvid encode), but its the same with everything i pass to it as far as i can see. Width, Height, AR, Framerate all match what gspot tells me. Anyway:

XviD
Standard:
Width: 480
Height: 352
FrameRate: 25.0

Standard:
Width: 544
Height: 400
FrameRate: 25.0

XviD
Standard:
Width: 720
Height: 400
FrameRate: 25.0

etc. (these are just the avis i have at hand, all were PAL).

Is what i'm getting from the dll. I don't have the GUI.
Just doesn't detect if its PAL or NTSC.

yes, when versioning it not only helps tracks the source, very often the PAL sources look for more vibrant than the NTSC by and large in this case.

MediaInfo used to offer standard calls, but they don't seem to work since several revisions back and Standard no longer returns everything.

I mean i can just use fps as an indicator to get the same information, just that bit neater if I can have mediainfo can do that instead of using some finickerty system :)

If you're talking about digital video, PAL and NTSC don't exist anymore. Those were norms for analogue broadcasting. The only place where PAL and NTSC remain in digital world are DV and DVD-Video formats. Here you have video files, which are better optimized for PAL or NTSC (resolution and framerate).

Where do you think MediaInfo could get an information, what was the source of an AVI file?

Framerate, its not just resolution that defines the TV standard afaik (right?)

so 25fps, cropped video isn't pal anymore? Damn. I know pal in 1967 meant something different to what it is now (strict colour code, etc.), so dvd pal isn't pal either. I've always said PAL/compatible is 25fps, ntsc is 23fps/29fps, its been the simplest most descriptive usage. Obviously res defined the hz of a tv too.

I guess i was assuming it meant what standard the video was, not whether it was fully standard compliant. I'll just use framerate to determine standard rather than calling standard in that case :)

The reasoning is pretty simple. Consider a standalone divx/xvid player hooked up to an pal tv. People get problems with their tv, ntsc rips (fps) often don't play on pal tvs and pal rips (fps) often don't play on ntsc tvs, as well as the preference of people watching and the effect of the framerate if the person is perdantic. I wanted to define whether it was pal sourced or ntsc sourced.

Usually original movie sources are saved on film cells (no resolution) and with 24fps. They are not PAL neither NTSC compliant. If studios create PAL DVDs, they speed up the movie to 25fps, scan the cells and resize picture to 720x576 (original PAL standard says 625 lines, but only 575 of them are visible, this is where 576 comes from). 720 is just because somebody thought it was a good idea (I don't think so).

NTSC DVDs are created with a technique called 3:2 pulldown, which splits frames into fields and then duplicates some of them. The resulting framerate must be 29.97 (30*1000/1001 exactly). It creates nasty interlacing artifacts when watched on a PC, so you'd better convert it back to 24*1000/1001 ~ 23.976fps.

So if you run into 23.976 fps movie, you have both possibilities - speed up to PAL or 3:2 pulldown to NTSC. NTSC DVD resolution is 720x480. It comes from the analogue norm again.

Also according to my knowledge, there are usually no problems with NTSC DVDs on PAL players, but there will be problems with PAL DVDs on NTSC players - Japan an USA usually don't care to much about the rest of the world.

No, text output is only informative, you can have tags/other info depends on the video file.
If you want exactly a piece of information, you can use the DLL API, or the "custom output" (in beta version in lastest releases) :
MediaInfo --Inform=Video;%Width% video.avi
to have video width on the 1st line for example.
MediaInfo --Help-Inform for more info, you can use file templates if needed, and I will continue to improve this feature.

Just doesn't detect if its PAL or NTSC.
I will work on it again, I may miss something in latest releases.

Where do you think MediaInfo could get an information, what was the source of an AVI file?
There is a flag in MPEG-1/2 Video stream for PAL or NTSC format.

Because I didn't have the time to connect parsers together (between the container parser and the video parser), this is planned.

This is planned, but I need more example of AVS files, could you send me some example you would like I support?

While trying to get megui running under vista x64 I found that the problem with megui under vista x64 is mediainfo. It is throwning an access violation exception when the method mediainfo_get is called. I am using 0.7.4.3

Any plans to get it running under a 64 bit platform? We don't need 64 bit, we actually have to have 32 bit to work with AviSynth.

I have been working on getting mediainfo to compile (under xp 32 for now) with no success. I have the lib compiling but the dll cannot find mpeg4ip.lib. I am using all the lib's you included in the zip file but that one is not there.

Any chance you have all the external libs in a vs2005 project somewhere? I have not compiled all the external libs, trying to follow your compiling instructions on sourceforge does not work.

I can help test an x64 version. I am running vista ultimate x64 w 4 gigs ram and an e6600 on my test box. It has vs2005 installed c# and c++ and 64 bit compiler.

There are two things that are needed here, a 32 bit version that will run under vista x64 and a 64 bit version. Apps like MeGui are 32 bit so they cannot load a 64 bit dll.

MeGui needs AVISynth which is 32 bit. There is a 64 bit version but until all the necessary filters are ported to 64 bit MeGui cannot run the 64bit version of AVISynth. Practically speaking I am not sure this will happen for a long time.

So the real priority (for MeGui) is getting the 32bit version of MediaInfo running on a 64 bit windows box. Personally, I would also like the 64 bit version of MediaInfo for some other programs.

I was trying to get a good compile so I could debug it and see where its failing at but compiling has been quite a bear. My c++ skills are very very rusty.

Well it turns out the problem was not in mediainfo. The problem was in the wrapper that MeGui uses to connect to mediainfo. I have fixed the wrapper and hope to get it to the MeGui team soon.

I have talked with Zenitram about AVS parsing. There are a couple of problems with AVS files.

The file is just text, it would have to be rendered to pull any info out
MediaInfo is cross platform AVS is a VFW renderer
Rendering the stream to get information would break the current methodology used to get video info within MediaInfo
There are so many plugins etc... that it would be practicably infeasible to figure out all the options
figuring out the underlying streams would not be helpful as so much can change by the time they are rendered.

What is needed is some form of avisynth probe to get media information from the avisynth file. I don't think this should go into the MediaInfo dll since it wont be cross platform.

With the previous version I used to get an approximation (1:2.35), now 16/9 all the time.
I did a stupid writing error in the AspectRatio string algorithm :
"if (AspectRatio >1.70 AspectRatio F1<2.85) AspectRatio_String=_T("16/9");"
(yes, stupid... 2.85 instead of 1.85)
For all codecs and containers, because it is in the core.
You can see the exact value with Menu Debug --> Advanced mode (in Tree or Text view)

So the exact value is always right, but not the string shown (I changed it because it was not enough precise) used in classic views.
Will be OK in next version 0.7.4.5 or next development snapshot.
2.35 will be shown if DAR is between 2.30 and 2.40, I hope this is not a too big aproximation.
Don't hesitate to write me more bugs!

PS : please use the tracker of sourceforge for bugs

I just discovered the new function in MediaInfo, the --Inform parameter. It is exactly what I need for my application. But the parameters are split into different groups (General, Video, Audio etc.) I would need a mixture of these parametrs, how can I do it? Or do I have to run MediaInfo 3-times to get all the parameters?
Directly from the Command line, you currently can have only one group. I am thinking about how to implement multiple groups.
But you can give to MediaInfo a file directly (I forgot to put it in the help), example :
MediaInfo --Inform=file://Example.csv "TEST.EVO"
General : D:\Programmation\MediaInfo\Release\MSVC\CLI\TEST.EVO
Format : MPEG-2PS
Length : 179 MiB for 4mn 49s 472ms

Video #0 : VC-1
Aspect : 1920 x 1080 (1.778)

Audio #0 : AC3+
Infos : , 48 KHz

Text #0 : RLE

Text #1 : RLE

Text #2 : RLE

Take a look in the /plugins/custom directory for examples (how to create Example.csv)

And by the way there is a small bug in the examples for this function (--Help-Inform). It displays the CL as MediaInfo.exe -Inform=..., bu the correct should be MediaInfo.exe --Inform=... It took me some time before I found out why it isn't working.
Oups. Corrected in the CVS, will be OK for the next release.

Note : Kurtnoise, your given values are for the programming interface only, from the command line "names" are used.

Hi,

I want to use the commandline tool to get variables for the stream length or the aspect ratio but I always fail.

For example: I have a AC3 stream and I want to have the lenght of it. Can someone give me a working commandline - many thanks. :)
For AC3 :
Command : MediaInfo --Inform=General;%PlayTime% FileName.ac3
Command : MediaInfo --Inform=Audio;%PlayTime% FileName.avi
Result : 1256960 (in milliseconds)
Command : MediaInfo --Inform=Audio;%PlayTime/String% FileName.avi
Result : 20mn 56s

Note : during the verification of the command, I noticed that lenght in the audio part (MediaInfo --Inform=Audio;%PlayTime%) for an AC3 file is lacking. I will correct this.

For AspectRatio :
Command : MediaInfo.exe --Inform=Video;%AspectRatio% FileName.avi
Result : 1.777
Command : MediaInfo.exe --Inform=Video;%AspectRatio/String% FileName.avi
Result : 16/9

Command : MediaInfo --Info-Parameters
Result : list the available parameters (between %)

JoeBG

16th June 2007, 10:17

First of all thanks for your help. :thanks:

Here the results from my test.

I used the following commandline:
mediainfo --Inform=Video;%AspectRatio% C:\files\****\Daten\VTS_01_1.VOB

The result is the same as if I would have used
mediainfo --Inform C:\files\****\Daten\VTS_01_1.VOB

=> mediainfo.exe shows all informations and ignores *Video;%AspectRatio%*

I do have the same result with AC3 streams. mediainfo.exe shows always all informations and not the selected ones. :confused:

Maybe I´m doing it wrong, but I used exactly your commandlines :)

Herewith (http://joeb.movie2digital.com/mediainfo.7z) my versions of mediainfo.exe and mediainfo.dll

You do have to use the command-line version; the command-line commands don't work with the GUI. (They have the same name, which makes it unnecessarily confusing. I always rename mine mediainfo-cli.exe. Even nicer would be if the GUI recognized cli commands and emulated it, removing the need for two executables...)

I already tested to have different names, GUI users want a short name rather than mediainfo-gui, CLI users too, so impossible to have all people happy :) (and you are the first user I know who use both! :) )
But yes, the GUI version will parse CLI options in the future.

I used a bat-file in my tests. When I type everything in my cmd-box without using a batchfile everything works for me too. Very strange everything :(

My plan is to use the variable %PlayTime% for further actions in DOS. But I think I cannot use it as %PlayTime% for further calculations isn´t it?

The current syntax to get particular parameters using Inform is a little odd in Linux. Bash interprets the semicolon as the end of a command/line and tries to execute whatever comes after it.

Workaround is currently:
MediaInfo --Inform=xxx\;%param% file.ext

the ";" is useful because I use internaly CSV format (semi-colomn, as in Europe...).
I don't plan to change this soon.
You can use a file too:
MediaInfo --Inform=file://SpecFile file.ext
And SpecFile contains "xxx;%param%"

If I add an option for accepting commas too, will it be better?

mihakase

9th October 2007, 10:33

Commas would be nice. I personally don't mind the semicolon but I figured the behaviour was worth noting anyway.

On a side note, I'm looking through mediainfo lib's source; trying to figure out how it gets an FLV's dimensions since I kind of need to implement that in php. It would probably help if I were a bit more competent though... no go as of yet. :)

In PHP, it will be diffucult to call MediaInfo library (written in C/C++), why don't you use mediainfo command line?
I heard about several user who call mediainfo from PHP without problems.
./mediainfo --Inform=Video;%Width% %Height% for example.

On another note, since many programs use MediaInfo dll now, can it be placed in a path directory to avoid multiple copies and for better updating? (On Windows)

Will that affect these programs (I guess only their authors would know)?

GL
How DLL works on Windows:
- Search in the .exe directory
- Search in the path

If you delete yourself the .dll in the porgram directory, the program will search in the path.

this is not a problem from the DLL, but from any third-party programs mainteners.

For MediaInfo (the GUI), the status of MediaInfo.dll is not "stable", so I prefer to not force updating. After, others do what they want.

When MediaInfo.dll is more stable, I may propose to install in a shared directory. Not now. (the version 0.x, not 1.x ;-) )

I was using MediaInfo in my PHP-GTK application from command line. No I decided to move a little further and switch to Python. I heard somewhere it should be possible to use a C/C++ dll in Python. Does anyone have any idea (or code sample) how to use the mediainfo.dll in Python?

Thunderbolt8

26th November 2007, 02:30

would it be possible that mediainfo could give the length of both, audio and video stream inside a container file? dont know which of these 2 is meant with the general "length" info of the file.

27th November 2007, 23:57

I made Python load MediaInfo.dll through ctypes (http://python.net/crew/theller/ctypes/). But when I try to call the function result = lib.MediaInfo_Open("video.avi"), then Python complains there are not enough parameters for the function. What other parameters should be there?

Sorry for probably stupid questions, I'm just a beginner.

foxyshadis

28th November 2007, 03:56

You have to use:

handle=lib.MediaInfo_New();
result=lib.MediaInfo_Open(handle,"video.avi")
MediaInfo_Delete(handle)

now.

A friend of mine wrote a Python wrapper for the .dll so it is solved. I didn't have the time to dive into the code yet, I just verified it works. If anyone's interested in it, let me know.

Anyway I have another problem. I'm not sure if MediaInfo is supposed to handle elemantary streams, but I think it usually does. I have a h.264 stream demuxed from AVCHD camcorder. MediaInfo 0.7.5.5 reports it as an AC3 audio. A sample can be downloaded here (http://www.sendspace.com/file/cpgtaq) (7 MB).

sure...upload a sample please. Same thing for the raw AVC (the link to download the file is dead).

The problematic .TS file is uploaded at http://www.sendspace.com/file/xjfw21. I think the problem with AVC stream is general, because it happend to me with more files. But if you can't reproduce it I will reupload the sample again.

Also I have some features requests for MediaInfo. I'm now working on a program, which uses MediaInfo library to get information about media files and then displays the needed modification to transcode it to DVD-Video. I also plan to add more output formats and maybe some day even make it a simple to use transcoding tool.

Here is the problem I currently have:
I need to know video compression. I need to know if it is MPEG-1/2/4 ASP or AVC. Or any other compression format. I use the "codec/family" information to get the compression, but it only works for AVI. In other containers the video compression is found under "codec". I could workaround it, but I think this inconsistency should be fixed in MediaInfo.

Second problem is, that for Matroska files the DLL only displays Mk. Again I could workaround it very simply, but I think I should mention it.

Also I'd like to ask you if it is possible to indicate some more informations about H.264. For example B-frames, CABAC etc. Is it possible at all?

Also I get much more information from a RAW AVC stream then from the same video muxed in MKV. Why?

3rd January 2008, 01:25

O.K., so I'll be more specific. This what I get from an MKV:

Hlavní #0

Hrací čas : 22s 880ms

Bit rate : 5833 Kbps
Šířka : 1440pixely
Výška : 1080pixely
Poměr stran : 16/9
Frame rate : 25.000 fps

The SW used to create the video is clear. Sorry for the Czech description, but even if I switch MediaInfo to English, the text remains in Czech. But it should be clear what the parameters are.

Now the same file after demuxing in MediaInfo 0.7.5.6:
Hlavní #0
Celý název a cesta : C:\_avchd\video4.264
Velikost souboru : 16.2 MiB

And now the same file in 0.7.5.0 (CLI, but it would be the same with GUI version):
General #0

Complete name : C:\_avchd\video4.264

Format/Info : Advanced Video Codec

Codec profile : High@L4.0
Width : 1440 pixels
Height : 1088 pixels
Aspect ratio : 4/3
PixelAspectRatio : 1.000
DisplayAspectRatio : 1.324

So first of all there is a bug in newer versions of MediaInfo that they don't read RAW AVC streams. With the older version 0.7.5.0 there are no problems. Also as you can see, I get different information about the video stream when it is demuxed. From a RAW AVC stream I get the information about profile, but not bitrate, framerate and time. Neuron2 says it should be possible to read framerate information from an AVC stream.

Also aspect ratio doesn't match. Any idea why?

If you can't reproduce it and want to see this sample video, let me know and I'll upload it.

Yes, I had problems with AVI OpenDML files in the last versions because I try to parse the Index chunks for having the real video stream size, and there was bugs in it with OpenDML indexes...
I will release a version today (0.7.5.8), please test it with the biggest AVI you have, this should be a lot quicker (lot of speed improvements), and give me your feedback.

By the way, is it possible to make the window of MediaInfo remember its size? I hate having to resize the window manually every time to see everything in Text mode.

This is planned, but not he most urgent.
(I am completly rewriting the GUI, for being cross-platform...)

I also have a suggestion/request:

Could you make a simplified version of the GUI that is only capable of displaying the info as plain text output. No fancy options. Just a 'browse for file' button, a text field, and perhaps a copy-to-clipboard button.
Preferably statically linked with the mediainfo lib, so that everything is in a single executable file.

For me, what you demand is simple :
- You configure MediaInfo for showing Text by default (in the main configuration window)
- in Win Explorer, right clic on the file, "MediaInfo", and you have the text (I must put a button "copy to clipboard here...).

Anyway, a guy wrote a tools which can be what you want:

(not supported by me)

Preferably statically linked with the mediainfo lib, so that everything is in a single executable file.
Not planned currently for official release (doable from source easily).
I can't manage tens of versions with CLI/GUI/DLL, Windows/Linux/Mac, 32/64 bits...

Thanks Atak_Snajpera, that is exactly what I had in mind. A simple and small tool that doesn't require installation.

That's great. Many thanks.

Also the consistency of video strem information in different containers is now much improved:

Many thanks for your work.

If I could have one more request: Would it be possible to display delay and stretch of audio in MKV? It is very important when converting such file.

I've just made this simple gui http://www.mediafire.com/?d5yommkdxnz

I like this, Atak. Any chance you could make it so that it remembers the window size or at least resizes itself automatically to fit all the info?

Also, a way to change the font from hard to see grey to black would be good too. Oh, any chance to give it an argument? I'd like to be able for it to load a file by either commandline or creating a right click "MediaInfo" option.

Other than that, I like its simpleness and speed.

Clsid asked for simple GUI so nothing more will be added. BTW This is dark grey (96,96,96) and have no problems with reading text. I suggest to calibrate your monitor :)

Allowing to open a file through command line would be a useful addition. That would for example allow a user to open a file in MediaInfoRaw through a "Send to" shortcut.

Edit: typo

Monitor _IS_ calibrated. I just prefer black text on white to grey text on white.

Bah....when I suggest it you dismiss it. When clsid suggests it you listen :-P

Thanks for adding it. I'll definitely use it now. It's so speedy!

Edit:
A little request. Could you make the window a bit wider? 50% or so. Now some stuff is getting word wrapped.

MediaInfo 0.7.6.0 cannot detect VC-1 video

MediaInfo 0.7.6.0 cannot detect VC-1 video
It detects VC-1 video on my .evo example files.
I don't have .ts (or .m2ts) files with VC-1, so I don't know what is the "stream_type" registered in the TS_program_map_section.

Please contact me (zen@mediaarea.net) for providing me an short example (you can create a 512K file with the official MediaInfo GUi, menu debug, "create a header file"), or if you can't, at least provide me the stream_type (in the official GUI, menu debug, "details - 10", load a file and search for "stream_type" in the text).

thanks for this example file, it is very useful.
I corrected problems, VC-1 will be detected in next version.
btw, PCM stream will too (but not a lot of information, I don't know to parse the PCM stream for finding the count of stream, the bitrate... If you have information about the PCM specifications in bluray, I am interested in :) )
And Dolby TrueHD stream will be detected as TrueHD, no more AC3 (but not a lot more information, I have only A/52B specifications, and there are no information about TrueHD :( )

Example of output with my development version for your file:
MPEG-1TS: 63.6 MiB
1920*1080 (16/9), at 24.000 fps, VC-1 (Advanced@3)
English, 640 Kbps, 48 KHz, 6 channels, AC3
English, PCM (Big / Signed)
English, 48 KHz, 6 channels, TrueHD
Chinese, 448 Kbps, 48 KHz, 6 channels, AC3

I will try to improve my MPEG parser for not detect your dts file as MPEG...
