Failed to recognize E-AC3 + Atmos audio track.

[Hongyu Shi]

I recently downloaded some shows (in mkv container) with eac3+Atmos audio (768kbps, standard streaming format). Mediainfo can show track codec correctly, however, Subler failed to recognize it (only “E-AC3”), and the output file is broken (no sound in QuickTime/Apple TV). Any idea of how to fix this?

VLC and mpv can play the output videos correctly, but QuickTime capability is broken (confirmed with different TV Shows from different sources).

Additionally, both 1.6.6 release and latest debug versions have this bug.

New progress: Atmos works fine in 1.6.5 release or earlier, only 1.6.6 have this issue.

Additional info: broken files are always 7 bytes smaller than normal ones. Something’s missing.

There were a lot of changes in the mkv demuxer In 1.6.6. I probably broken something. Can you share a sample of a non working eac3+Atmos mkv file?

Here are both working & broken sample hosted on Google Drive:

The mkv file would be more useful.

OK. Added to the share folder. Please check!

Thanks, fixed in 1.6.7.
