Have you tested DLL v0.7.0.2 (do not work on v0.7.0.1...)? I tried with some MKV files, and it works

Note : for Debugging, I need the "debug" output (Debug-->Advanced mode) to have all indicators.

But, maybe the best is to use private messages for debugging...

[Sirber]

I got the 0.7.0.2b. I will make more tests. Do you have msn?

problems with "Language". In Martoska, japanese is "jpn" while MI gives me "ja". Any clue why?

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"!

[Sirber]

ok, thanks! I will convert

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)

Is there any explanation about this on the Gpac site (I've never found anything similar on gpac.sf.net)? Any commands for MP4Box?

[bond]

i never really tried mp4box' meta options, you might want to talk to jeanlf about this

Hi,

I'm a realanime dev and i'v incounter a problème using media info dll. We extract FPS to make sure that the output will be correct.

with few files (that have a fps of 29.96999 that i'v found with matroska shell addon) when i try to find the fps with MI, it give me that :

Video #0 : DivX 5
Aspect : 704 x 528 (1.333) at %fps% fps

i'm unable to find FPS in this file

source is a MKV.

*MediaInfo version : 0.7.0.4

** when the file is extracted, we can have


Thank you

LAIN

MKV isn't generally supported in mediainfo, sadly. For my own tools I parse the output of mkvverify (mkvinfo would also work, but mkvverify is very compact and gives more info).

[Zenitram]

I did not have time to work well on Matroska, so the support is not good at this time.
But I plan to have a better support soon (maybe next release)
Sorry for the delay.

Yes, I did not have time to work on mkv, sorry.
But a v0.7.1.1 will come in few weeks, and I plan to work well on this missing fps in mkv...

[Zenitram]

OK, Lain.
I succeeded to find FrameRate for all kind of video track (AVI codec, or Real, or AVC...)
I do some cleanups, and release a new version befor the end of the week.

[Sirber]

Nice! Even RV? Sweet!!

[foxyshadis]

Oh, zeni, one quick request, in case you have more time; can you also gather the bitrate for audio in mkv? That would be so helpful! =D Or is that still a difficult problem?

Thank you very much for the FPS

I'd like to post you another problem that I encounter using the version 0.7.1.1 that you'v send to sirber.

When we try to do --> MediaInfo_Open(handle, filename); <-- we have a Acces Violation in delphi... it said that it's in mediainfo.dll ... in the version 0.7.1.0 dev (5.18 mb) that we use tu try was working #1 without any error.

Thank you

I'm testing the last version with my Delphi tool and it works fine...pb with the Handle maybe.
