Find out why movies won’t play - OGPlayer - 2024-10-02
I have used Jellyfin for a few years and for the most part, if a movie won’t play I just download a different one. Can someone help me determine what causes a movie to not play? Is there a process to figure this out? Most of my movies will play and will frequently buffer.
I have an Epyc 7204 (16 core) and no GPU running TrueNAS Scale. Currently I’m the only one that uses Jellyfin and once I get this issue resolved and learn more about how it all works, I will look into adding a GPU to support more simultaneous streams. I feel my setup should be able to support at least one stream of 4K content but if I’m wrong, please let me know.

Did you disable transcoding and remuxing? Depending on the codec and container of your video, if the client doesn't support some aspect of the video the client will request a transcode or remux. If those are disabled then the client will not be able to play the video.
Can you share your full jellyfin log via pastebin?

Under the admin dashboard -> Playback -> hardware acceleration = “None”
I’m not aware of any remux settings. Is that the same as hardware acceleration?

1) Your videos are dolby vision 7.6. Only a PC client using Jellyfin Media Player of MPV Shim would be able to play without transcoding.
2) It is trying to transcode and failing. Additionally, it is doing super weird stuff in the transcode. The kind of weird that tells me something isn't setup right.
Can you share your docker compose with us?

Ahh, yes, iso. Please don't. iso may or may not work and if it does not we can do very little about it

1) That's odd because I thought it was turned off.
I'm running Jellyfin on TrueNAS so there aren't any options to configure other than directories. I can try to get what what your looking for if necessary. Not sure if the next reply about .iso's is the issue. I will do some testing to see.

The "None" setting is strictly for hardware acceleration. When set to none it will use the CPU for all transcoding. There is a setting to turn off transcoding and remuxing in the Users dashboard but, as gnattu pointed out, ISOs are not well supported by Jellyfin regardless if transcoding is enabled or not. In fact, we specifically advertise that Jellyfin doesn't support ISOs. It might work sometimes, but usually doesn't. Since the limited ISO support we do have is inherited by upstream applications and libraries.
