Title: Audio Track Language Description Lost
Post by: Ares Drake on October 10, 2012, 01:25:45 PM
Using Avidemux 2.5.6 and 2.6.0, there seems to be a problem handling the tack audio description.

I just cut out commercials. Audio and Video on copy. Source file hast language description for the audio track(s) embedded.  Language Description can be read e.g. with mediainfo: http://mediainfo.sourceforge.net/

Saving the outfile using either the avi muxer or mp4v2-muxer, the outfile no longer has the language description.

Could that be changed, so the language description doesn't get stripped?

avidemux 2.6 only
Main Menu -> Audio -> Select Track
mark the additional track(s) you wan to keep (up to 4)

Thanks for your quick reply. However what you answered does not answer what I asked. Maybe I made myself not clear. The tracks are in the outfile. But they lost their description.  I can no longer probe what language a track is.

Confirmed with ADM 2.6. Tested on a MP4 video (with one audio track with description 'de'): Cut the commercials, save the file in Copy Mode as MP4 (MP4v2 muxer). Audio track descriptor has gone.

The label(s)/identifier(s) of audio tracks are not read/used/transfered by avidemux. 1st understood the track itself was gone.
I move the track that I want to hear as default to track 0. See this thread 2.6 audio track switching in job.py  (http://www.avidemux.org/smf/index.php?topic=10499.0)
And hope some day developers find the time to solve the labeling of audio tracks. And keep the subtitle tracks too if present.

Can I place a monetary bounty for that feature?

I'm afraid: not. Avidemux is a limitiedThe few Developer(s) setting their priorities and work down the list. They look at requests, if interesting and feasible these do sometime pop-up along in the development. Problems are handled along the same line: (temporary/definite) (patch/fix) if possible are dealt with.
Bribes, bounties: none are accepted.
Currently the best way: give a detailed report and try to provided answers to follow up questions/request made by developers/forum staff/admins. (the blue blocks people).
Be patient, polite, ...
Don't: make impossible requests, apply pressure, ...

My opinion. I'm not involved with avidemux or the forum. I'm a heavy avidemux user
