Description: No audio tracks in QuickTime
Version: 0.8.2 (via brew package manager)
Steps that will reproduce the problem?
- Find a video that contains more than one audio track
- ffmpeg -i _video.mkv -timestamp now -vcodec libx264 -acodec libfaac -alang eng video.m4v -acodec libfaac -alang ger -newaudio
- open -a QuickTime video.m4v
What is the expected result?
To be able to select the audio track and to hear only one track at once.
What happens instead?
No audio tracks selectable. All languages/tracks are mixed into one audio
Open the file with VLC.
Any additional information:
Same issue with the latest libav version (although the parameters are a bit different). Also iTunes has the same issue und I'm sure an iOS device will have it too. But it seems to be a known issue since a long time: https://www.lscube.org/issue2534
I applied this patch but this only enables Quicktime to select an audio track - if no track is selected (default): all tracks are played all together.
