Cannot Play mp4 files - Noctris - 2025-03-19
Hello all,
I have this strange issue where I cannot only play season 1 of a specific series, that can be opened in MediaPlayer, Bs Player and other apps, so I'm not really sure what's wrong with it.
I have the logs but I don't know how to read these, from the looks of it I would say it's trying to convert something, but I'm not sure what to what since I'm trying to play it from the same PC that is hosting the files, I have an RTX2060 that does the transcoding.
If anyone can help and take a peek, I would be grateful!

Conversion failed!RE: Cannot Play mp4 files - TheDreadPirate - 2025-03-20
What version of Windows and what Nvidia driver version are you currently running?
And can you share screenshots of Dashboard > Playback > Transcoding? It looks like you have "MPEG4" checked. Can you try unchecking it?
RE: Cannot Play mp4 files - Noctris - 2025-03-20
Running Windows 11, latest update.
Nvidia Driver V572.83
You were right, MPEG4 transcoding was turned on. As soon as I turned it off it started working.
Here is my Transcoding Settings at the moment (not sure how to upload a screenshot, so here it is in txt)
Is there anything else that I need to disable here? Thank you!

RE: Cannot Play mp4 files - TheDreadPirate - 2025-03-20
Uncheck both HEVC Rext boxes.
For the record, you are probably still transcoding the video you were having issues with. But the video is now being decoded by the CPU instead of the GPU. That's what those boxes at the top control. Which codecs the GPU will DEcode. If unchecked, the CPU will DEcode the video instead of the GPU. But only when transcoding.
AFAICT, your GPU does not support MPEG4 decoding. Not sure which, if any, Nvida GPU can based on their matrix.

RE: Cannot Play mp4 files - Noctris - 2025-03-20
Thank you very much for the awesome insight!
I'm still playing around with JelyFin, just installed it on my PC to see how it works, how to set it up, etc. but do plan on getting a dedicated media storage system for it.
Again thanks so much!
