Guide<\/h3>\n\n\n\nAssumptions<\/h4>\n\n\n\n
This guide asumes, that you already have an up and running Proxmox system.<\/p>\n\n\n\n
Downloading the CT template<\/h4>\n\n\n\n
Goto your storage (local or external) and choose CT Templates. Next click on “Templates” and search for debian-13. Select the debian-13-standard template and download it to your storage.<\/p>\n\n\n\n Click on the “Create CT” button top right of the Proxmox webinterface. <\/p>\n\n\n\n After creating the container and starting it, install the latest updates and some tools.<\/p>\n\n\n\n Open \/etc\/apt\/sources.list and check if all required repositories exist. Add missing ones.<\/p>\n\n\n\n In order to use the repository, you need to import the signing key first<\/p>\n\n\n\n Then add the repository<\/p>\n\n\n\n Now that you have added the plex repository, you can install the plex server + all required packages for hardware transcoding. (If you use an NVidia or AMD card, you have to install the drivers for your card, not the intel ones)<\/p>\n\n\n\n In order for Plex to access the GPU, the plex user needs access to the render device.<\/p>\n\n\n\n In order to use the GPU as transcoding device, you have to map the GPU from Host into the Container.<\/p>\n\n\n\n First you need some informations about the Plex user, run the following command inside your Plex container.<\/p>\n\n\n\n Note the UID and GID for the plex user (in my case they are 999 and 996)<\/p>\n\n\n\n On the host run the following command:<\/p>\n\n\n\n This should display the available Direct Rendering Infrastructure (dri) devices. Ignore the “by-path” entry and note the others.<\/p>\n\n\n\n In Proxmox Webinterface, go to your plex server container, choose resources, and add the found devices. Check the “Advanced” checkbox and enter the UID and GID for the plex user.<\/p>\n\n\n\n Without this mapping, the plex server will not be able to use the GPU as transcoding device<\/p>\n\n\n\n Reboot your container, then check if the GPU is visible to the system. (if you use an AMD or NVidia card, you have to search for those drivers when using the lsmod command)<\/p>\n\n\n\n I will not guide you through the plex setup here, but after the setup is completed, you should be able to select the Hardware transcoding device in the plex server settings<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" This blog post is a guide to install a Plex server on an Proxmox LCX Container with working hardware transcoding.
