Unable to Fast Foward direct play

Is this for ALL videos or only particular videos? Are these problematic videos MKVs? If so, you can try recontainerizing the videos. Sometimes poorly authored MKVs can cause this issue. The command below will repackage all the video/audio/subs without re-encoding.

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

Also, for Firesticks, you should explicitly select libVLC as the preferred player. For non-Firesticks I recommend exo.
