This client isn't compatible with the media and the server isn't sending a compatible media format

[Litarvan]

I am using an old LG TV (55EC930V) with webOS 1.4. I managed to make everything work (though it was pretty hard) but I'm stuck at video playback.

Though I have transcoding enabled (which works well on a regular PC using a browser), when trying to play any media (x246, HEVC, ...) on my TV using the webOS application, it tries out for a moment then tells me that this client isn't compatible with the media.

Client-side logs show that several media are tried without success:

Please post the ffmpeg log. The first one. The 2nd and 3rd are retries with forced transcoding.

Side note. I sanitized the api_key in your post, but can't delete the original one. Logging out will probably invalidate it.

[Litarvan]

Thanks for the API key, I revoked it.
Jellyfin doesn't seam to produce FFMPEG logs in this specific case, I only see logs from when I tried on my PC and it worked, but not for my tries on my TV. I checked both in the dashboard "logs" section and in the container logs.

😕
Reverse proxy?
Could you try connecting the server directly (by IP:port + http) to bypass it?

[Litarvan]

Wow you are right, it works. Didn't think such an error could have anything to do with NGINX, I guess it fails to stream the media properly? Though I don't get why it only happens with my TV...

Thanks a lot, I'll try to debug my NGINX config. By any chance, do you have any idea where I should look at?

[dmitrylyzo]

Here it was caching of wrong MIME type.

[Litarvan]

After hours of struggling I found out that even without NGINX, direct play was working but not transcoding. When I try to play HEVC, it produces the same error. It's a bit strange, sometimes I managed to see the first seconds of the video playing properly but then it stops and displays the error. Sometimes it just black screen when I try to play it but if I try to forward or anything it displays the error too.

I tried on my main instance without NGINX (using Ngrok TCP proxy), but I also tried to launch a fresh Jellyfin instance on my laptop with Docker and accessing it locally and it did the same.

If it helps, here are the server logs of my local reproduction : https://code.litarvan.com/acipayug.yaml ; [12:57:40] is the moment I tried fowarding since it was just stuck on a black screen. The client logs are here : https://code.litarvan.com/iqisaxiv.sql . Again, it works seamlessly from my computer, these issues are only on webOS :/

I'm starting to think it's just not possible to make this work under webOS 1

And also, here are all the FFMPEG logs produced :

[whoamiUNIX]

I'm facing the same issue as above. Behavior are the same. It only occur if jellyfin is behind proxy. Direct ip:port did not cause this issue. I found that issue occur only for mkv formats on Android device.

[mannes]

Had the same issue, interface worked well, no video playback when using reverse proxy.
Using haproxy as reverse proxy. I solved it by allowing TLS 1.2 (instead of at least 1.3). Works with mozilla ssl's intermediate profile.
Solution probably applicable to other proxies too. Make sure TLS 1.2 is enabled
