Another NVENC question

sllim126

Proxmox running on HPE DL380 with GPU passthrough to Windows 10 VM.

GPU is a Quadro P2200. It's detected in Windows without issue, encoding/decoding in Plex occurs without issue.

When enabling the FFmpeg Profile I setup for 4K streaming, the system defaults to the CPU. From what I can see, ErsatzTV can see the GPU and even starts to load something, but something crashes, and I don't know enough about ffmpeg to know what to change. So any support would be helpful

Here is my Troubleshooting > Nvidia Capabilities

It's a little non-obvious, but this actually indicates a successful capability check:

[h264_nvenc @ 000001635ea31200] [ GPU #0 - < Quadro P2200 > has Compute SM 6.1 ]

Would need to see more about how things are actually failing. Maybe turn streaming log level to debug in ETV's main Settings page, restart ETV, then try streaming again and see what the logs say.

Thank you for the response! I've really enjoyed the software so far, and appreciate all the hard work you've put in!.

I'll make the adjustments, and report back

sllim126

Well, Playback is working now. I didn't change anything other than changing the log level for streaming to debug.

Thank you for your assistance, even though it was resolved!

jason

Okay, glad it's working. Note that ETV/ffmpeg will use software decoding when the video format cannot be decoded by your NVIDIA hardware, which will increase CPU load, depending on the specific source content. Hardware acceleration is not necessarily on all the time or off all the time.
