Jellyfin supports hardware acceleration of video encoding/decoding/transcoding using FFMpeg. It supports multiple acceleration types, including AMD AMF, Intel Quick Sync, OpenMax OMX, nVidia NVENC, Intel/AMD VAAPI, and others.
Enabling Hardware Acceleration
Hardware acceleration options can be found in the Admin Dashboard under the Transcoding section. Select a valid hardware acceleration option from the drop-down menu, indicate a device if applicable, and check
enable hardware encoding to enable encoding as well as decoding, if your hardware supports this.
The hardware acceleration is available immediately for media playback. No server restart is required.
Each hardware acceleration type, as well as each Jellyfin installation type, requires different setup options before it can be used. It is always best to consult the FFMpeg documentation on the acceleration type you choose for the latest information.
Configuring VAAPI acceleration on Debian/Ubuntu from
Configuring VAAPI on Debian/Ubuntu requires some additional configuration to ensure permissions are correct.
Configure VAAPI for your system by following the relevant documentation. Verify that a
renderdevice is now present in
/dev/dri, and note the permissions and group available to write to it, in this case
$ ls -l /dev/dri
drwxr-xr-x 2 root root 100 Apr 13 16:37 by-path
crw-rw---- 1 root video 226, 0 Apr 13 16:37 card0
crw-rw---- 1 root video 226, 1 Apr 13 16:37 card1
crw-rw---- 1 root render 226, 128 Apr 13 16:37 renderD128
NOTE: On some releases, the group may be
Add the Jellyfin service user to the above group to allow Jellyfin's FFMpeg process access to the device, and restart Jellyfin:
sudo usermod -aG render jellyfin
sudo systemctl restart jellyfin
Configure VAAPI acceleration in the "Transcoding" page of the Admin Dashboard. Enter the
/dev/dri/renderD128device above as the
VA API Devicevalue.
Watch a movie, and verify that transcoding is occurring by watching the
radeontopor similar tools.
Hardware acceleration in a LXC/LXD container (tested with LXC 3.0, may or may not work with version 2)
Follow the steps above to add the jellyfin user to the
render group, depending on your circumstances.
Add your GPU to the container:
$ lxc config device add <container name> gpu gpu gid=<gid of your video or render group>
Make sure you have the card within the container:
$ lxc exec jellyfin -- ls -l /dev/dri
crw-rw---- 1 root video 226, 0 Jun 4 02:13 card0
crw-rw---- 1 root video 226, 0 Jun 4 02:13 controlD64
crw-rw---- 1 root video 226, 128 Jun 4 02:13 renderD128
Configure Jellyfin to use video acceleration, point it at the right device if the default option doesn't
Try and play a video that requires transcoding and run the following, you should get a hit:
$ ps aux | grep ffmpeg | grep accel
You can also try playing a video that requires transcoding, and if it plays you're good.
Hardware acceleration on Raspberry Pi (tested on RPi3)
- Add the Jellyfin service user to the video group to allow Jellyfin's FFMpeg process access to the encoder, and restart Jellyfin:
sudo usermod -a -G video jellyfin
sudo systemctl restart jellyfin
OpenMAX OMXas the Hardware acceleration on the Transcoding tab of the Server Dashboard
Note: In testing transcoding was not working fast enough to run in real time because the video was being resized. The Pi 3 is likely not fast enough to resize as part of the transcoding.
