Would it be too much of a leap to provide support for detecting CD-TEXT (http://en.wikipedia.org/wiki/CD-Text) data. Which Sony (and their affiliated companies) place on their audio CD's?
do you have a sample to provide ?

cdda support is on the way...

CD-Text is directly in the CD-Audio (in the CD subcode data), you need a specific API to interface with the hardware CD player. So no one can provide a sample (or is an ISO image of a CD-TEXT is enough? and I am not sure a Virtual CD software interface can expose such data)

And according to this web site (http://bmproductions.fixnum.org/index.htm?http://bmproductions.fixnum.org/moreprogs/wmpcdtext.htm) they have a "plug-in" for Windows Media Player...

Also, Nero Burning ROM offers the ability to create your own audio CD's with CD-Text ;)

EDIT: I've just tried the "plug-in" with WMP 12 and Win 7 - It appears to work just fine. VLC player 1.1.10 also seems to recognise CD-text...

Could you implement framecount and full duration (up to ms) if possible? I always find myself wanting to know that oftenly

Already implemented.
-f with command line
-Menu debug, advanced mode with GUI

This is not by default, but you can create your own template.

Hi Zen,

I found a problem when reading tags from Ogg Vorbis files. If the files have an "Album Artist" tag, MediaInfo returns the information in "Performer" field as "album artist / artist". But I would need these 2 value separated. It works correctly with MP3s, where the values are returned in fields "Performer" and "Album/Performer".

This happens with all Ogg Vorbis files I have. I use foobar2000 or mp3tag to tag my files. Both programs read the tags correctly.

Is this behavior intentional for some reason? Could you have a look at it please? If you need a sample file, please let me know. But it should be reproducible with any Ogg Vorbis file.

Thanks!

Edit: Also I think that to name the Artist field as Performer might be confusing. For example foobar2000 has a separate Performer field. I think that Artist field is meant to contain music author (Mozart, for example) and Performer would be the orchestra that actually plays it. It probably only matters for classical music, but why not make the field names consistent with other programs?

I am open to some proposals about fields mapping, but they must be consistent and more "logical" than the current mapping.

"Artist" field is used for so many different people (as you said: this can be the performer, or the music autor), I try to separate and to precise roles when I can. Additionaly, Id3v2 has the same field for Artist/Performer (TPE1), and I must choose a name ;-).
I currently don't agree to fill a different field depending of the genre (e.g. in "Artist" for U2 and "Performer" for the performer of a classical music.), I (and my users!) expect the same field in every case whatever is the genre, so currently "Performer" name seems to be the more logical.

foobar2000 goal is to propose fields from the underlying format, MediaInfo goal is to display same field whatever is the underlying format.

So... If you want a change in the mapping and/or naming, I need a proof this is better for everybody in any case (for pop music up to classical music, from Id3v1 to MP4 tags)

vlada

21st July 2011, 21:23

I think that using Artist and Album artist is very common and most people would expect these fields. Using different field names for different genres is certainly a bad idea.

I think that the track artist/performer should be stored in a field called "Artist". You might copy the value to "Performer" field if a different performer value is not stored in the tag.

It is not important, it would just make MediaInfo more consistent with other programs, which all use "Artist" for this information. But of course the decision is up to you and your commercial partners.

Btw. a funny thing is, that we have no good translation for "Artist" in Czech. We usually translate it as "interpret", which means performer.

Actually none of my commercial partners care about this field, so I can decide a change without too many complains (at least no complain with financial impact :-D ).

Btw. a funny thing is, that we have no good translation for "Artist" in Czech. We usually translate it as "interpret", which means performer.

Another good reason to use "Performer" :).
I was using "Artist" previously, it was changed due to some requests from other people, people do not agree at 100% on the the naming, so currently I think I keep this field name as is.

No, no, and no. I don't care of K-Lite. This GUI is not made by me, this is not a confirmation. This is not an older version, this is another software. If you want to compare, compare with my software, not the tool from someone else.

OK. I checked the dependencies of the GUI .exe, this is weird, there is a hard-coded link to Windowscodecs.dll and dwmapi.dll but without any function called in theses DLLs. Argh this new version of Embarcadero RAD Studio! I must trash it ASAP...

Yeah, yeah... I was wrong. (or I wansn't: I still don't know if theses files are in default installation of Windows XP, or with some Windows update. The thing I did is to remove the useless link to theses DLLs, this does not mean that this DLLs are expected not to be there)

His GUI is his choice, this is not my choice and the choice of my users. You have choice, you can choose Atak Snajpera GUI if you prefer it.
For info, you can select "Text view" as default and remove menu bar in preferences screen, then you have nearly the same GUI than Atak Snajpera one.

If you still use MSVC 9.0 to make your builds, then probably nothing.

But I use MSVC 10.0 for quite some now and therefore the binaries won't run on Windows 2000 without the fix :rolleyes:

I use MSVC 9.0 for CLI versions of MediaInfo for this reason actually, I was afraid you mean that my version was not working anymore with Windows 2000.
Worse, I use MSVC 8.0 (MSVC 2005!) for 32-bit DLL in order to be compatible with Windows 95 ;-) (yes, some crazy people still use Windows 95, and they use up to date MediaInfo... I force myself not to try to understand this)

(64-bit versions are built with MSVC 10 because all 64-bit OS are currently supported).

Such limitations from Microsoft is a bit frustrating...

It actually is pretty easy to get MSVC 10.0 binaries running under Windows 2000.

In my test even complex stuff, such as the Qt-framework, appears to work flawlessly this way.

People even try to run Win32 GUI applications on DOS, using the HX Extender ;)

To be fair, the backward compatibility provided by Microsoft is pretty good compared to, let's say, Apple :devil:

head -c 100000 filebig.ext > filesmall.ext

May fail.
May not fail.
This depends of the content of the file (if header is at beginning or at end of the file, if index is included in the partial file...), format (for MPEG-TS, you'll have the duration of the partial file...).

MediaInfo is designed to provide maximum info it can with partial files. But there is no list of circumstances, currently (nobody has requested such thing).

This is in the pipe on my side, but with a C++ server, in order to have fine control about when and how to cut the connexion (MediaInfo DLL API provides fine control of when to cut instead of a hard-coded value)

p.s. my usual avi and mp4 files do pass the head test.

This is a bit cryptic for me :).

It definitely is cryptic :scared:

Unfortunately the only way to convert an operating system file HANDLE into a normal C-style FILE pointer (as needed to replace 'stdout' and fix the 'cout' object) is converting it into a CRT file descriptor first, by calling _open_osfhandle(), and then converting it further to a FILE pointer, by calling _fdopen(). For the 'cout' we additionally need to wrap it into an std::filebuf object...

But it's more or less what Microsoft recommends, except that we explicitly do not want "text" (aka "UTF-8 mangling") mode:
