GPAC MP4Box Information, Feature Requests & Discussions [No bug reports]

[SeeMoreDigital]

Hi Rodoga,

Just so as you know... This thread is not for discussing bug reports or muxing issues with MP4box.

[hxhxd]

I have a problem about anamorphic muxing. My cmd is:
mp4box -add 1.264:par=32:27:fps=29.970:layout=854x480 -add 1.mp4 -psp -new 1-muxed.mp4
whenever I remove layout=854x480 or change par value from command line, the final resolution stays at 720x480.

the raw video stream is encoded correctly, as mplayer can confirm this.

My question is, how to create a anamorphic file?

thanks very much!

Hi everybody,

actually I'm having a strange problem mit MP4Box.
I have a full PAL AVC encoded video and two AAC streams of audio. All in RAW format. I'll try to mux them into one .mp4 file using MP4Box on a Linux machine. I tried the same on Win Vista and it fails as well.
All streams togeter make a total of aprox. 5 GB, and I observed that the application crashes when the total filesize is over 4 GB and there are more then just one audio track. I did multiplexing of a 20GB file without any problems, but with only one audio track.
As soon as you try to add another, it'll crash.
If you stay below the 4GB plimsoll line, it works perfectly

Any help would be highly appreciated

Here is the output:

MP4Box -fps 25 -par 1=1:1 -add "Tine Tauchen_Track1.h264" -add "Tine Tauchen_Track2.aac" -add "Tine Tauchen_Track3.aac" -new "Tine Tauchen.mp4"

Development dead?

Latest version 0.4.6-DEV (build 1) tends to crash a lot.

[RBO]

GPAC is not dead! And we're glad to see it used by doom9 forumers :)

However we can't browse the whole web for your remarks! If you see any bug or want to contact us, post on our forums (https://sourceforge.net/projects/gpac/forums) or send a PM. Please don't forget to provide us with sample files to reproduce your behaviour. :thanks:

Despite our commitment to provide a decent level of support, if you fell your bug/request gets too much time to be processed, we remind you GPAC is an open-source project. This means you can also help us improving it by submitting patches. We will be happy to merge them :)

This thread is yours!!

There is a bug in all MP4Box versions I've tried since 2010-04-10 builds when using the built-in tagging system: the file is getting tagged the day before it has been created.

2010-09-05 instead of 2010-09-06.

I'm using MP4Box through Yamb 2.1.0.0 beta2 but it was working fine with older versions.

GPAC uses wrong epoch offset 2082758400 according to 14496-5 reference sofware.
Correct offset is 2082844800.
(This is the fault of ISO reference software.)

I don't know why GPAC guys had begun to use the wrong offset.

Thank you for reporting! The fix has been committed: https://sourceforge.net/apps/trac/gpac/changeset/2024/

Small question: is there a way to extract the nhml of a track without extracting the track at the same time?

[RBO]

No you can't. What are you trying to do?

Was thinking about some general mp4->XY conversions and since I need the nhml files to handle vfr, but when not remuxing, most tools handle mp4 files better than raw streams I was wondering if it is necessary to extract the videotrack to get the nhml file. :P

[Dogway]

I have an avi file with 2 audio streams and I want to demux the secondary audio so I do:

mp4box -aviraw audio2 "source"

is this correct?


EDIT: nevermind solved it with virtualdub

Hi. I contacted the bug tracker:

https://sourceforge.net/tracker/?func=detail&aid=3164751&group_id=84101&atid=571738

I understand - this is not a bug, but if possible I would like to return to the issue.

I compiled a new version from SVN:

MP4Box.exe -version
MP4Box - GPAC version 0.4.6-DEV (internal rev. 8)
GPAC Copyright: (c) Jean Le Feuvre 2000-2005
(c) ENST 2005-200X
GPAC Configuration: (static configuration file)
Features: GPAC_HAS_SPIDERMONKEY GPAC_HAS_JPEG GPAC_HAS_PNG

now there were additional message while concatenating:

MP4Box.exe -force-cat -cat 1.mp4 -cat 2.mp4 -cat 3.mp4 -new a.mp4
Appending file 1.mp4
No suitable destination track found - creating new one (type soun)
No suitable destination track found - creating new one (type vide)
Appending file 2.mp4
WARNING: Concatenating track ID 2 even though sample descriptions do not match
Appending file 3.mp4
Saving a.mp4: 0.500 secs Interleaving

MediaInfo shows 6 seconds of video/audio and only one video track, everything looks good, but unfortunately VLC is behaving exactly as well - video stops after two seconds of playback.

@Kurtnoise
or anyone who can help with this

In itunes and apple devices, when there are multiple tracks
It will display each track as <language> ( <Type Track #> )
For ex: English ( Audio Track 1 )

If the trak.udta.name atom or userDataName
is populated it will use that in place of <Type Track #>
For ex: English ( Dolby Surround )

Itunes and apple devices are not reading the trak.hdlr.name or handlerName
that I can use with name= for a track

How I currently deal with it is I use mp4box like this

mp4box
-add Video..h264:lang=en:name="AVC Video"
-add Audio_track2.aac:lang=en:group=1:name="Mono"
-add Audio_track3.aac:lang=en:group=1:disable:name="Stereo"
-add Audio_track4.aac:lang=en:group=1:disable:name="Dolby Surround"
-add Audio_track5.aac:lang=en:group=1:disable:name="Dolby Pro Logic"
-add Audio_track6.ac3:lang=en:group=1:disable:name="AC3"
output.mp4


I use the mp4track.exe to check to see what is there

mp4track "output.mp4" --list

track[1] id=2
type = audio
enabled = true
inMovie = false
inPreview = false
layer = 0
alternateGroup = 1
volume = 1.0000
width = 0.00000000
height = 0.00000000
language = English
handlerName = Mono
userDataName = <absent>

I then add the userDataName string with mp4track.exe

mp4track "output.mp4" --track-id 2 --udtaname "Mono"

I use the mp4track.exe to check to see that it is there

mp4track "output.mp4" --list

track[1] id=2
type = audio
enabled = true
inMovie = false
inPreview = false
layer = 0
alternateGroup = 1
volume = 1.0000
width = 0.00000000
height = 0.00000000
language = English
handlerName = Mono
userDataName = Mono

Is it possible to add the userDataName string to a track with mp4box ?
I was hoping I could do it with -add-arg

If it is not possible, sure I'll keep using mp4track
But would it be possible to add this feature to mp4box?

Hi phibertron,

Just so as you know... This thread is not for discussing bug reports or muxing issues with MP4box

[phibertron]

Ah I see, i'll make it post in the forum, thanks

[Gew]

Hi guys!

Simple question. I've noticed that I can easily set language and title names for tracks which I chose to mux into an .MP4 using GPAC MP4Box.

Eg.
mp4box -add video.mp4:name=MyVideo -add audio.aac:lang=eng:name=AnAudioTrack -new output.mp4


However, say I want to set a title name for the entire "mux", i.e. what is shown at the container section of MediaInfo output. Is there any way (that I don't know of) so I can set this with MP4Box? Right now I have a work-around by simply running the file through the good ol' ffmpeg.

Eg.
ffmpeg -i output.mp4 -vcodec copy -acodec copy -metadata title="My cool project with audio and video" output2.mp4

However, this "extra step" feels really silly and stupid if there is actually a way of doing it right through MP4Box. Therefor, I ask you guys, do you, by any chance, know of any?

Regards~

:thanks:

[Oleg Rode]

GPAC developers don't read this thread...better use the SF website. It's freely available and doesn't require registration.
So MP4BOX is a part of GPAC project, isn't it? Is it okay to ask at SF about new features for MP4BOX?

Just wanted to ask about 3D video support in mp4box.

[Kurtnoise]

by 3D video, you mean MVC ?

[Oleg Rode]

by 3D video, you mean MVC ?
No, take a look at this file.
http://www.mediafire.com/file/odt7tw9j1xsh3yw/OA3DDEMO.MP4
The video goes at a 2 x 29.97 = 59.940 fps. CODEC is AVC, yes?
At least all Sony 3D HW players (PS3, BRAVIA TV) recognize 3D content in it.
Looks like this file has a special "3D content" flag in a header. I tried to demux streams and make a new mp4 file with a same framerate, but 3D HW player doesn't recognize 3D content in it.

[jamesN]

Hey everybody. . .
By default, mp4box adds date fields to every stream in the muxed file.
I read the documentation many times, but i can not find a switch to stop adding these dates, currently i have to run ffmpeg on the file to remove those dates, so could you please add a switch to stop adding those dates to the file?

[vsv]

Hello!
It is possible to manipulate (mux/demux) with MVC stream inside mp4 from JVC TD1 stereoscopic camcorder, or convert m2ts from Sony TD10 to mp4 by using mp4box ? Thanks!

[jfcarbel]

for who wants to know "-chap" switch add chapters in NERO style ONLY...the new ":chap" switch add chapters in APPLE style ONLY...

the APPLE style chapters are assigned to the first audio/video track...chapters are working fine with QT, iTunes and VLC but haali media splitter (1.7.401.3) displays them as subtiles!!!


Have not purchased myself a tablet yet but looking to get one for holidays. Will these Apple chapters style work on the default video players on iPads and Android tablets?

[Selur]

normally I use:
MP4Box -par 1=1 -add "x264Video.264"#video:fps=23.976 -ipod -new "test.m4v"
to multiplex H.264 raw stream in an iTunes compatible way into a mp4 container. (works fine)
now I got a MPEG-4 ASP video (only) stream and if I use:
MP4Box -par 1=1 -add "xvidVideo.avi"#video:fps=23.976 -ipod -new "test.m4v"
the video is not shown in Quicktime&Co.
If I use:
ffmpeg -i xvidVideo.avi -c:v copy "test.mp4" the file plays fine.

-> is there a way to remux MPEG-4 ASP with mp4box in a way that iTunes&co support it?

Cu Selur

[LoRd_MuldeR]

Did you use "MP4Box.exe -diso filename.mp4" to check what makes the files different?

[Selur]

Nope,... problem is I'm unsure what to look for :/
muxed with ffmpeg: http://pastebin.com/58i9PKeu
muxed with mp4box: http://pastebin.com/dZmjTNXE
-> any help is appreciated :)

[LoRd_MuldeR]

Well, there's a quite obvious difference right at the beginning, in the "ftyp" atom:

<FileTypeBox MajorBrand="isom" MinorVersion="512">
<BoxInfo Size="28" Type="ftyp"/>
<BrandEntry AlternateBrand="isom"/>
<BrandEntry AlternateBrand="iso2"/>
<BrandEntry AlternateBrand="mp41"/>
</FileTypeBox><FileTypeBox MajorBrand="M4V " MinorVersion="1">
<BoxInfo Size="28" Type="ftyp"/>
<BrandEntry AlternateBrand="isom"/>
<BrandEntry AlternateBrand="M4V "/>
<BrandEntry AlternateBrand="mp42"/>
</FileTypeBox>

[Selur]

there are so many differences,... that it's hard to know what's important, so I thought some one here probably would have used mp4box to remux Xvid content for iTunes&Co and could say something more.
-> will look further into it tomorrow. (need some sleep now :))

[LoRd_MuldeR]

Well, I'd say a difference in the "ftyp" atom, which is an "file type" identifier for ISO Media (MP4) files, is a good candidate for compatibility issues.

Interestingly it seems to make a difference whether you let MP4Box save the output file with a .MP4 or .M4V extension :eek:


Also note the following related MP4Box options:
-brand ABCD[:v]
Sets the major brand of a file. Brands are used to identify the most common usage of a file (MPEG-4 presentation, 3GP movie, etc…). If ‘v’ is set, also sets the version of the brand (default version is 0).

-ab ABCD
adds an alternate brand to the file. Alternate Brands are used to identify the other possible usage of a file (whether the 3GP file compliant with MPEG-4, etc…)

[Selur]

Normally iTunes&Co files need the .m4v extension otherwise chapters&co are not identified properly,..

[Selur]

found the problem:
MP4Box -par 1=1 -add "xvidVideo.avi"#video:fps=23.976 -ipod -new "test.m4v"
needs to be:
MP4Box -par 1=1:1 -add "xvidVideo.avi"#video:fps=23.976 -ipod -new "test.m4v"
DOH,...

I miss still a function to copy metadata. It has already been repeatedly reported and probably not achievable in MP4Box.
MP4Box.exe -new -info -add "(video+audio).mp4:????(copy itunes)" -add "subtitle.ttxt/srt" "output.mp4"

I wonder also why any cover (webp, bpg, jpeg2000, others) and the name cover we can't use attachment(add-item) in the function itunes. For me it is an unnecessary duplication of functions "cover" and "set-meta/add-item". :(

Edit:
How to transfer metadata information to the newly created MP4 file? :idea: As we know, no such function "copy UDTA types: meta (1) chpl (1)" and could be a problem because the metadata information using -add functions are cleared.
Use a trick if you want to enter additional subtitles, chapter or cover.
mp4box.exe -add "subtitle.srt" -add "chapter.txt" -itags cover = "*. jpg,*. png" output{metadata}.mp4
Note:!: output{metadata}.mp4 file metadata is overwritten by newly added function. If muxer something wrong to do it the original file isn't recoverable.

- Use m4v or m4a as output extension in order to activate Apple devices support.
- only jpg and png are supported as well for Apple devices. See MP4Box -tag-list switch...

[Jamaika]

- Use m4v or m4a as output extension in order to activate Apple devices support.
Theoretically, yes. Unfortunately, everyone knows that Apple fought with MP4 and Apple implemented container MOV for all video codecs. So the struggle the worlds with Microsoft continues today.
MP4Box doesn't support MOV.

- only jpg and png are supported as well for Apple devices. See MP4Box -tag-list switch...
It is known for years with documentation help. Only apparently we have a world of new codecs photo HEVC/VPX. Hence my whining.
