Lossless media edits causing playback issues in AndroidTV client

I'm not sure how AviDemux works in the background, but one thing you can try is to repackage the file.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags genpts -i "/path/to/video.mkv" -map 0:v -map 0:a -map 0:s -map_chapters 0 -c:v copy -c:a copy -c:s copy outputFile.mkv

This will copy the video, audio, and subs unmodified and just regenerate the packet time stamps. Jellyfin, and a lot of the players Jellyfin uses, are not very tolerant of faults and out of spec files.
