Direct Play works only when "allow transcoding" Turned Off

[TheDreadPirate]

I'm wondering if it's because the audio you want to play is the second audio track. Some clients, when playing MKVs, will need a remux if you select an audio track other than the first audio track. Which is the usual behavior for browsers. And WebOS is a glorified browser, including our app.

In the "problem" video, the FLAC track you are playing is the second track.

For testing, can you try remuxing the problem video so that the FLAC track is the first track? The command below should remux (no encoding) so that the second audio track becomes the first track, and copies the rest of the streams.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/data/Media/Video#1.mkv" -map_metadata 0 -map_chapters 0 -map 0:v -map 0:a:1 -map 0:a:0 -map 0:a:2 -map 0:s -map 0:t -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled newFile.mkv
