SOLVED: Playing .webm on Google TV (Sony)

[Kotor1984]

I was using the Jellyfin app on my Sony TV running Google Android. When playing movie with webm file extension, Jellyfin app cannot play it, always error.

Is this not supported on Google TV? The TV model is Sony X95L (2023).

If I use Jellyfin app on my Android phone, and stream it to TV via Chromecast, it works.

So, I am wondering if there's any way to fix this issue.

Can you share your logs with us? And what codec is the video using? webm is is just the container.

[Kotor1984]

I think the problem might be the AV01 codec. I changed to MP4, same error.

If I choose VP9+MP4, no error. I tried different video with AV01, always error.

AVC1+MP4, no error.

Edit (thedreadpirate): please don't talk about how you acquired media here.

If I use Jellyfin app on my Android phone, stream to Chromecast to the same TV, it can play AV01+MP4/webm successfully.

Your server is trying to transcode but can't initialize your Intel iGPU. Can you describe your setup? Looks like your OS is Ubuntu 20.04. Any virtualization? What are your hardware specs?

[Kotor1984]

The Jellyfin is installed on Proxmox LXC container. Hardware is Beelink U59 Pro with Intel processor N5105. I thought I got the hardware transcoding works, but now I am not sure anymore. Is there any way to test it?

[TheDreadPirate]

Playing HEVC in Chrome or Firefox will trigger a transcode to H264.

Also, what codecs did you select in the Playback dashboard?

If you selected accelerated DECODING of AV1, your iGPU doesn't support it. Uncheck the box and it will software decode.

The AV1 is not selected in the Transcode settings:

Here is "vainfo" command, it can open the driver:

Also this info:

root@jellyfin:~# groups jellyfin

jellyfin : jellyfin video render

I also tested playing HEVC on Edge, got the same error

[AVHWDeviceContext @ 0x55797eeddc00] No VA display found for any default device.
Device creation failed: -22.

I solved it!

I read this post:
Intel Quick Sync Video not working. : jellyfin (reddit.com)

Then I did this on the Jellyfin LXC:

root@jellyfin: /# chmod -R 777 /dev/dri
root@jellyfin: /# ls -l /dev/dri
total 0
drwxrwxrwx 2 root root        80 Oct  3 16:15 by-path
crwxrwxrwx 1 root video  226,  0 Oct  3 16:15 card0
crwxrwxrwx 1 root syslog 226, 128 Oct  3 16:15 renderD128
root@jellyfin: /#

Then I can play all those videos with AV01 codec on my TV using Jellyfin app, also HEVC from Edge working.

New log playing AV01:
/videos/cdf8fccb-0183-cecc-0cbb-142999d7a164/hls1/main/0.ts{"Protocol":0,"Id - Pastebin.com

New log playing HEVC on Edge:
/videos/90d6baae-85e6-acc3-0f5a-4a1d9e2e77a5/hls1/main/0.ts{"Protocol":0,"Id - Pastebin.com

Those indicated that hardware acceleration transcoding works, right?

So, it was permission issue. That solution does not look nice (chmod 777), but at least it works.

Do you know what should be the correct permissions?

[TheDreadPirate]

You should be adding the container user to the group that owns renderD128. For some reason "syslog" in your output. Changing the permissions to 777 will be reset next reboot. But adding your user to "syslog" (usually "render") will survive reboots.

[Kotor1984]

Yes, that's it.

I added this on the LXC configuration:

lxc.hook.pre-start: sh -c "chown 0:44 /dev/dri/renderD128"

That set the correct group during restart of the system:

root@jellyfin:~# ls -l /dev/dri
total 0
drwxrwxrwx 2 root root        80 Oct  3 16:15 by-path
crwxrwxrwx 1 root video 226,  0 Oct  3 16:15 card0
crwxrwxrwx 1 root video 226, 128 Oct  3 16:15 renderD128
root@jellyfin:~#

Issue is fixed :)
