Hi there, I’m new to Plex and this is my first post. What I’m requesting is : Hardware Accelerated Decode with Nvidia Cards for Linux. I think this feature will be super helpful to cut down the CPU overhead when transcoding videos on a Linux server. I’m using plex server with Ubuntu(18.04 beta) fo…

It’s an issue because the plex transcoder is an outdated version of ffmpeg. They need to update it to v4+ before enabling NVDEC support. Emby uses a newer version ffmpeg which is why it doesn’t have the issue.

Someone wrote a netdata plugin to graph GPU usage as well. For anyone interested. [image] coraxx/netdata_nv_plugin NetData plugin for Nvidia GPU stats. Contribute to coraxx/netdata_nv_plugin development by creating an account on GitHub.

I’ve been unsuccessful at compiling the repo above, after digging through a dependency hell I cant get past this on a Ubuntu 18.04 LTS Server. LD ffmpeg_g /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: e…

@Ryan_Cassidi Can you share a docker image or what you have to get to that far in building ffmpeg? One of us may be able to help get it further.

nvtop is useful as well if you haven’t already played with that.
