Playback error on Chrome/Edge browsers

[malvar]

Uncheck low power encoding.  That requires additional setup that can't be done on Synology NASes.  It isn't required anyway.

Good to know.  I unchecked low power encoding, resaved, restarted, verified.  Still getting the same error.

I appreciate the assistance here. I've tried the official installation guide, and numerous videos specifically for Jellyfin on Synologly NAS, and also tried to follow several of the forum guides here. I've tried debugging using the logs, but am so far out of my element that I usually just go down rabbit holes of issues that aren't really related to my problem. It's frustrating for a beginner. So, it's really nice that the community here is so helpful.  Thanks, DreadPirate.

Any other ideas on what could be going wrong? I verified that I can run the video in question directly using VLC, and can still view it through Jellyfin on my Android phone.  Just not Chrome or Edge browsers.

Share screenshots of how you currently have Dashboard > Playback setup.

Sure thing. Attached.

After unchecking low power encoding, can you share a fresh log? I need to verify whether or not the root error is the same.

@Efficient_Good_5784 - Are there any other settings not in Docker compose that they would need to double check to ensure the GPU is properly passed into the container?

This may be a red herring, but I noticed that when I ran this last test, two errors popped up and I got two FFmpeg logs.  They're identical except for the transcode locations (/cache/transcodes/01246187ea372c3a5c986634828f543c.m3u8 for one, /cache/transcodes/354879e775d15d756731a5169d12190d.m3u8 in the other).

Can you try unchecking MPEG2 in the decode list?

The playback still fails, but the errors in the logs are different.

Looks like it actually started transcoding this time. But it isn't transcoding the audio, for some reason. Browsers don't support 5.1 Dolby Digital, AFAIK.

Did you try using VAAPI for HWA?

I tried switching to VAAPI. I still get an error when I try to play the video, but the FFmpeg logs look like it's getting a lot further.
