Avidemux Forum

I have an MP4 with DTS-HD Mater/5.1 audio. However, Avidemux shows the audio track as Unknown codec, 6 chan. I need to edit the video using keyframes and save as Copy. When I try to save with Audio Output: copy, I get an error message. Unsupported Audio track 1 out of 1 is incompatible Only AAC, AC3, DTS, E-AC3, MP2, MP3 and Vorbis supported for audio. If I change the output to AAC, the video won't play correctly. If I change it to AC3, Avidemux freezes and won't respond.

Does this happen with the latest available 2.8.2 nightly build?

If it does, please provide a sample.

If the file size is too large for the file to be provided as a sample by the usual tools as WeTransfer, Mega, Dropbox or Google Drive, please at least attach MediaInfo textual analysis for the file in question to your reply (don't try to paste it into the body of the post, CleanTalk is allergic against MediaInfo for whatever reason).

But it will if you disable the DTS audio track, right?

It still happens with the latest nightly build.

Thank you, might be fixed now, but can't tell for sure without a sample. Please try a future nightly build.

Please send me a PM with the link, thank you.

Thank you for the sample. By pure luck, Avidemux happens to play audio fine in this sample now, but in general, support for DTS audio descriptors in MP4 must be implemented.
