LG Smart TV Jellyfin App

[.theviceroy]

Hi, 
I've tried looking this up but really haven't found a satisfactory answer. I have a LG Smart TV which is using the official store app to access my Jellyfin server. Most things play just fine, but there is an issue when it comes to HEVC Main 10 content. Sometimes it plays fine, others it plays audio with no video and sometimes it plays audio/video but if the content is paused or skipped forward/back it completely stops playing and you must reset the content from the beginning.

• I have messed around a bit with the LG Smart Tv xml file and added ‘hevc’ to the direct play profiles, but that did not solve the problem. Also, I specifically looked up my tv model and confirmed that it could play HEVC 10 bit content, which is listed in the video codec specs.
  
• There does not seem to be any correlation to video resolution, it is an issue with 1080p and 4k content, seemingly at random.
  
• I have already disabled the ‘Prefer fMP4-HLS Media Container’, though that does not seem to have changed anything.
  

Lastly, and most frustratingly Plex direct plays the exact same files just fine on this tv, so I know it has to be something with the jellyfin app.

Specs:
Jellyfin Server Version: 10.9.8
WebOS: 6.4.0-21 and the app is up to date.

If anyone has any thoughts, I’d appreciate the help!

Can you share the full media info for one of these videos? From the Jellyfin UI.

Ok. So not even HDR. Can you replicate the problem then share your full jellyfin log via pastebin?

[theguymadmax]

Post the FFmpeg logs as well. Also, you're a couple of versions behind; it’s a good idea to update to the latest version.

[.theviceroy]

This issue has persisted over several versions of Jellyfin, but I will be updating soon.

FFmpeg logs: https://pastebin.com/Jw0wRpf8

[TheDreadPirate]

Can you share your full jellyfin log? Do you allow transcoding or remuxing? I don't recall seeing ffmpeg outputting to an MKV container before.

[.theviceroy]

Hey Dread, I think that information is in the first log I posted, though I'll be honest I am not the most experienced when it comes to reading these logs and understanding what is going on.

Remuxing is allowed for this user, but audio/video transcoding is not.
[02:12:45] [INF] [31] Jellyfin.Api.Helpers.MediaInfoHelper: User policy for USERNAME. EnablePlaybackRemuxing: True EnableVideoPlaybackTranscoding: False EnableAudioPlaybackTranscoding: False

Also, it that same log it looks FFmpeg starts and then exits?
[02:12:48] [INF] [29] MediaBrowser.MediaEncoding.Transcoding.TranscodeManager: /usr/lib/jellyfin-ffmpeg/ffmpeg -analyzeduration 200M -probesize 1G -fflags +genpts -f matroska  -i file:"/data/tv/Reacher/Season 1/Reacher - S01E01 - Welcome to Margrave WEBRip-1080p.mkv" -map 0:35 -map 0:0 -map -0:s -codec:v:0 copy -map_metadata -1 -map_chapters -1 -threads 0 -codec:a:0 copy -y "/config/transcodes/6b4dfa51742f6738a8932f802de258bc.mkv"
[02:12:52] [INF] [53] MediaBrowser.MediaEncoding.Transcoding.TranscodeManager: FFmpeg exited with code 0

What I really don't understand is that the play_method is listed as Transcoding but v:direct and a:direct? What does that mean?
[02:13:07] [INF] [31] Jellyfin.Plugin.PlaybackReporting.EventMonitorEntryPoint: StartPlaybackTimer : play_method          = Transcode (v:direct a:direct)

[TheDreadPirate]

Yep. You're right. Forgot about that (too many thread).

Your video is pretty strange, btw. Usually the video track is the first track, but in this case it is the last track. And I'm wondering if that is a factor. Or THE factor.

Do you have issues with any other video or just this video or series? I'm assuming this series is from the same source?

You can try remuxing the video and placing the video as track 0.

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "/data/tv/Reacher/Season 1/Reacher - S01E01 - Welcome to Margrave WEBRip-1080p.mkv" -codec copy -map_chapters 0 -map 0:v -map 0:a -map 0:s newFile.mkv

That should put the video stream back as the first track.
