Video stopping and then won't let me scrub

[TheDreadPirate]

Based some issues I worked through with other users, I suspect the issue is with the file itself.  Is your file in a MKV container?  If so, a couple users had success using ffmpeg to repackage their video to address skipping, stuttering, and problems scrubbing.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags genpts -i "/path/to/your/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

I have been using the web interface since I last captured the logs and it has been working flawlessly.  Today, I decided to go back to the JMP and the issue still persists.  If the problem was with the file, then I'd expect the web interface to have issues with it as well, which is not the case.  On a similar note, the JMP installed on Nvidia Shield is working flawlessly as well, same for the android player.  It's only the desktop install that has been having this particular issue

Actually, its kind of the opposite.  When it is transcoding, remuxing, or direct streaming, ffmpeg is repackaging the video in almost the same way the command I provided would.  JMP on a desktop is the most likely to straight up try to play the original file without any modification.

I strongly suggest you give the ffmpeg command I provided a try on one file.  Since it isn't re-encoding it will go through your file very quickly.
