GStreamer support for non-Tegra based cards?

I see that there is a wealth of GStreamer support for hardware-accelerated plugins, but not so much for anything else. I’m trying to utilize the Tesla K80 or M60 (running on ubuntu 16.04) for video processing and am having a hard time finding any resources. I tried using document (http://developer2.download.nvidia.com/embedded/L4T/r24_Release_v2.1/Docs/Accelerated_GStreamer_User_Guide_Release_24.2.1.pdf), but the plugins aren’t being installed, which I assume is because they’re specific for the Tegra X1 devices.

Is there a fundamental reason why there isn’t as much support for other cards? Or is there support and I just can’t find them?

I’m also interested in writing my own GStreamer video post-processing plugin utilizing CUDA and GPU and am also running into difficulty finding resources on that as well.

Thanks in advance!
