First, I have confirmed for all of the media which has been listed in this thread (that has issues) Jellyfin is remuxing, however for whatever reason the remuxing is going back into .mkv, which is what the original files are already in. I started going deeper into why these files are remuxing, but I can’t find anything linking them together, or proof. Somethings that might be the case though:
I also tried disabling the “Allow video playback that requires conversion without re-encoding” option and all the media that had been remuxing entirely failed to playback. It didn’t start or play audio or anything, just gave the error message and closed.
Is there anyway to change the default encoding output used by Jellyfin to test whether a different .mkv encoding method might work better?
- There is a disclaimer in LG’s documentation that states “Video files created by some encoders may not be played.” I have not found a comprehensive list of what video encoders are valid and which aren’t but as an example here is the encodings for the media that is listed in this thread.
- First Media Source encoding: Lavc58.134.100 libx265
- Media A Source encoding: Lavc60.31.102 libx265
- Media B Source encoding: Lavc60.31.102 libx265
- I also found that for media Jellyfin remuxes seems to default the encoding output using: Lavf60.3.100. I can not verify if this encoding version is compatible with LG, but it might not be so that could be the issue.
- I also checked a working file (.mkv, hevc, SDR) that did not trigger the remuxing and found its encoding to be: Lavc61.3.100 libx265
