SOLVED: Weird pixelation and stuttering issues when playing on Samsung TV app

Glad it works, but it is not a great solution, IMO.

Could you run this command and then share the resulting file with me via Google drive or something. Send me a PM with the link.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -i "/media/TV & Shows/Severance/Severance.S01E03.1080p.WEB.H264-CAKES[TGx]/severance.s01e03.1080p.web.h264-cakes.mkv" -vn -an -map 0:s -codec copy /tmp/serverance.s01e03.subsOnly.mkv

Share the resulting file written to /tmp.

Done!

I don't see anything obviously wrong in the contents of the ENGLISH subs. When I extracted just the english subs and did SRT to SRT conversion, that resulted in identical checksums. Which indicates that it isn't malformed. I did the same with every subtitle track and the "converted" subs all had identical checksums to the original.

For testing, let's try removing all the extra sub tracks you don't need and replace the original with the new file with just english subs. I'm assuming you're using the english subs based on the US flag icon in your forum profile. Please correct me if I'm wrong.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/media/TV & Shows/Severance/Severance.S01E03.1080p.WEB.H264-CAKES[TGx]/severance.s01e03.1080p.web.h264-cakes.mkv" -map 0:v -map 0:a -map 0:s:0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled /media/S01E03.mkv

Make a backup copy of the original, replace the original with the new file we put in /media, rescan your library, set subtitle burn in back to auto on your TV, try to play this episode again.

Okay so having done that, the issue of pixelation every time there is dialogue isnt happening anymore which is great. Only thing Im noticing now is what seems like buffering. The video will pause every minute or so for about 15 to 20 seconds, then goes back to playing. I do notice during that time, on the server's web client dashboard it says that Tizen app is working just fine and the elapsed time keeps going, as if it is de synchronized.

Oh man, I cant even stream anything at this point, burning subtitles or not, the loading times and the constant buffering are unbearable. I dont know if its related to this same issue or its something else entirely.

So this is happening to all your files now? Not just the couple you originally had?

Same show, only difference is this is in 4k as opposed to 1080p. I tried some movies I also had and they loaded up just fine and played w/ subtitles no issue. Im really at a loss here. Ill post all these logs and hopefully it uncovers something.

FFmpeg transcode for the movie

Jellyfin log

FFmpeg transcode

FFmpeg transcode (same show, next season)
Another FFmpeg transcode

As soon as I posted the last one I saw a ton of transcode logs so I decided to stop for now unless you need more please let me know

   


If it ends up I cant figure this out I think another solution would be to get me a docking station and just dock my laptop to the TV

From the server side of things, everything looks fine. I won't be able to setup your test file until I get home. I'll get back to you on that.

But if I don't find anything wrong with the file, besides your laptop, is some TV dongle something you can get? ONN TV boxes are pretty good and cheap. I also like Rokus.

TV dongle would be the best bet, cause I was going to expand to the non smart tv in the garage eventually. Im starting to think its just this TV itself is just shat itself from age. Unrealted, which would be the most stable dongle I should go with in the event I go that route? Dont get me wrong, I still want to get to the bottom of this issue though

Your test file, with subs enabled, plays fine on all my devices. So definitely something specific to your TV.
