This was an issue for 2.7.2 too but I just fot frustrated today and want it sorted.

- I make 2+ clips from a source video
- Each clip has E-AC-3 audio
- When I tried to append them together, there is no audio.
- (I think this happens if I've stopped/ended the clips at non-I frames using the -> button instead of the >> button)

-- What can I do (apart from redoing the individual clips) to get the audio working?
-- I have tried converting the audio to MP3 or AAC, for the new clip, but nothing seems to work.


Please provide a pair of samples to append which would allow to reproduce the issue.


Thank you, which application has generated the samples? Avidemux?


I see, the mp4 demuxer in Avidemux doesn't support E-AC3 yet. Should be fixed by [demuxers/Mp4] Add support for EAC3 audio tracks, thank you for raising the topic.

Yes. Avidemux

Also, this happens in mkv as well.

- With everything set to Copy,  it generates a message: Muxer Cannot open
- With audio set to anything else, it creates a clip without throwing an error but the clip doesn't even start in the latest MPC-HC, and starts in VLC 4.0 but without sound.


As explained above, the support for E-AC3 audio tracks in mp4 has been just added to the demuxer. It will be present in the next nightly.
