MVK Files - can't fast forward

[TheDreadPirate]

I'm experiencing the same problem in my older LG tv. Can't fast forward, can't go back, and if I restart the video, it always starts from the beginning (not from where I left it).

That said, it just works OK in my newer LG tv. Same video same jellyfin server. It just works.

So it looks that the older TV does not support some feature, or that jellyfin does not comply with something at 100%.

My question is: may exist a workaround so the older tv also behaves correctly?

Thanks!

Without seeing your logs, I can't say why it works on one and not the other.  Perhaps on the TV that behaves properly, it is transcoding or remuxing while it direct plays on your other TV.

90% of the time, the cause of this issue is some sort of problem with the MKV container.  The video and audio is fine, but the container itself is malformed in some way.  The solution is to remux the files, which does NOT require re-encoding.  Remuxing should only take a few minutes depending on how fast your storage is.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/path/to/your/video.mkv" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled newFile.mkv
