Video freezes but audio keeps playing

[TheDreadPirate]

Poorly muxed videos can trigger this kind of behavior. And videos from the same source may all exhibit the problem. You can try remuxing one of the videos to see if we can fix any container issues.

We'll use Better Call Saul from you opening post as the guinea pig. Open a command prompt.

Code:

cd C:\Program Files\Jellyfin
ffmpeg.exe -fflags +genpts+igndts -i "D:\TV Series\Better Call Saul\Season 5\Better Call Saul (2015) - S05E06 - Wexler v. Goodman (1080p BluRay x265 Silence).mkv" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled newFile.mkv

Make a backup copy of the original for now then replace the original in the library folder with the new file and test whether that new file works.
