When I try playing certain series, the audio starts to stutter a lot (unlistenable). The files in particular which have the problem are .mkv, most of the times they are anime with lots of subtiltes and audio files embedded into them. The files work perfectly on my pc and phone (through swiftfin). Anyone know what might be the issue? Thanks

Edit: It appears to only happen with audio marked with "Opus 112Kbps"

This appears to be an issue with some Samsung TV's.

The easiest solution is to remux your MKVs with OPUS into an MP4 container, which can be done without re-encoding.

How would one do this? I have multiple embeded subtitles and audio tracks in the .mkv files. I've tried with ffmpeg but no good results, either te style of the subs are gone, the audio tracks are gone, ...

Code:
ffmpeg -i /path/to/your/video.mkv -map 0 -c:v copy -c:a copy -c:s copy newvideo.mp4

Try that ffmpeg command.

Ah. Just remembered. MP4 does not support embedded ASS subtitles.

I'm surprised your TV isn't transcoding because of the subtitles. I'm assuming you are using the subtitles.

Yeah I am using the subs. I think my only fix would probably be redownloading all the anime I downloaded with the Opus audio. Because I just can't seem to fix it...

You could use ffmpeg to convert the just audio to AAC

Code:
ffmpeg -i /path/to/your/video.mkv -map 0 -c:v copy -c:a libfdk_aac -c:s copy newvideo.mkv
