A Plex container built from plexinc/pms-docker:plexpass with one minor addition to make hardware transcoding work on Synology

Plex, in Docker, on Synology, with Hardware Transcoding

The default Plex container runs perfectly fine on Synology, but hardware transcoding doesn't work.

There's a way to get it working by mapping in the /dev/dri devices, and changing their permissions, which has been described on the Plex Forums. However, the problem is that the permissions get lost every time the container restarts, or if the image is updated.

This repo fixes that problem by doing a nasty chmod 777 to /dev/dri every time the container starts.

¯\_(ツ)_/¯

HowTo

1. Grab the plex-synology image from Docker Hub, and create a Docker container on your Synology. Configure the Advanced Settings as desired (Consult the official pms-docker README for more information).
2. Export the container settings (Select <your container> > Settings > Export > Container settings)
3. Replace this line

      "devices" : [],

   with the following:

   "devices": [{"CgroupPermissions": "rwm", "PathInContainer": "\/dev\/dri", "PathOnHost": "\/dev\/dri"}],

4. Delete the container created in step 1
5. Import the edited json file; this should create a new container. (Select Settings > Import > <your edited json file>)
6. Start the new container, and then enable Hardware Transcode in your server settings. (Select Settings > Transcoder > Show Advanced > Use hardware acceleration when available)
7. 👍
