Hardware accelerated encoding not working

---

Expected Behavior

Hardware acceleration using docker on an Raspberry Pi 4

Current Behavior

Acceleration won't work

Steps to Reproduce

1. Spun up the docker container as described in readme
2. Made sure all mappings, etc. are correct
3. Tried to playback a movie from my library using my android device with transcoding set to 720p / 8 Mbit

Environment

OS: Raspbian OS full 64bit CPU architecture: arm64 How docker service was installed: get.docker.com standard method

Command used to create docker container (run/create/compose/screenshot)

docker run -d --name=jellyfin --restart=always --net=host --device=/dev/vchiq:/dev/vchiq -v jellyfin:/config -v /media/external:/media -v /opt/vc/lib:/opt/vc/lib -e PUID=1000 -e PGID=1000 -e TZ='Europe/Berlin' -e UMASK_SET='022' linuxserver/jellyfin:latest

Thanks for opening your first issue here! Be sure to follow the bug or feature issue templates!

It's not strange it can't find the lib as it's owned by root. So you need to give the user you used in PUID & PGID have permission to read the lib.

[nurtext]

That's wrong. As you can see above my permissions on host and container are both '-rw-r--r--' (0644) which means U+RW, G+R, W+R so everyone has read access. Anyway, I tried with setting PUID and PGID to zero (root) and it still doesn't work.

[j0nnymoe]

Did you try chowning it to the PUID/PGID before you decided that's wrong?

[nurtext]

• docker running as root (uid/gid 0)
• jellyfin running as root (uid/gid 0)
• libbcm_host.so owned by root and 0644

That being said, no need for chown'ing any system files (which is always a very bad idea). Anyway consider this solved, because I think I've found the issue:

https://github.com/jellyfin/jellyfin/issues/4023

Would be a good idea to have this information in README.
