Problem with LG TV Playback

[Vargavinter]

Hello. I've tried to search for a solution to my problem, but since English isn't my primary language, I don't know really how to formulate the problem. I have an Ugreen NAS which I play all my video files from, and I play them on my LG C1 TV using the Jellyfin APP. But now I just found a video file that works perfectly on my PC, but on my LG TV it freezes for a second to a few seconds every time at the exact same few spots. But when I run the video in straight in Windows 11 with VLC or if I run it through the web interface for Jellyfin in Brave browser, then it's working without flaws. It's basically only struggling on my LG TV (tried both wireless & wired), and so far this is the first video file that been giving me troubles. And I don't know how to troubleshoot it.

I'm running Jellyfin 10.11.0 on my NAS.

I don't know what logs you need from me, but here is my FFmpeg.Directstream log.

Try re-encoding your movie The Florida Project with one of the HandBrake 2160p presets and see if it then plays on the LG.

This may or may not be related, but I do have LG TV too, with similar problems. I noticed whenever iam trying to playback anything with subtitles type PGSSUB, it does struggle to play it smoothly. I just turn the subtitles off, or switch to something else. Works well.

Sorry for the delay, It's been much at home to do. I'm running it through Handbreak as we speak. I will get back to you with my findings!

Your file is a MKV file, and some clients (including the WebOS client) have a limited support for that container. And also, your movie is DV, and DV is very tricky when it comes to WebOS (the native HLS player is kinda buggy). Try remuxing the file to MP4 without transcoding to preserve quality and save encoding time, and play with the settings "prefer fMP4-HLS container" and "use shorter segments" on your WebOS client. Try enabling them both, and if it doesn't work, try disabling them both. If your file is MP4 instead of MKV and both settings are enabled, you may experience some stuttering, but the file should be playable.

Yeah, that's my experience so far. Until LG fixes its HLS player (if it does), most likely playback on WebOS will continue to be tricky, specially with DV. In my case, I couldn't get to a point where playback was acceptable (even with non DV files) with the current JF-Web release, and I guess that's because the use of hls.js was reverted. I built from source (master branch) and modified the code to use hls.js again and things improved a lot. In fact, with hls.js and having both fMP4-HLS and shorter segments enabled, I haven't found a movie that I would say it's unwatchable on my C1, just minor stuttering with high bitrate files.

Disabling fMP4-HLS made things worse in my case, both with the native player (weird, it's supposed to work better with that setting disabled) and with hls.js. So the configuration that has worked the best for me is using hls.js (either by building from source and modifying the code, or reverting to JF-Web 10.11.2 where hls.js was still used for WebOS) with both fMP4-HLS and shorter segments enabled. Disabling fMP4-HLS, in my case, regardless of the player used, always made things worse even with non DV movies. Consistency between TV models apparently is not LG's thing, it looks like almost every model behaves differently, so probably what worked for me will make things worse for others. But trying to play a DV movie in a MKV container on the WebOS client without any issues sounds like a difficult mission to accomplish.

All my library consists of MP4 files, no MKV files. Using MKV in this case might be contributing to the problem, so I would start troubleshooting by remuxing to MP4 first and play with both settings mentioned. If that doesn't work, I would try reverting JF-Web to 10.11.2 to see if using hls.js might help, while having both settings enabled. If that doesn't work, transcoding might be the only option, maybe sacrificing DV.
