Same thing here. Using R9 5900X and 7900XTX

thank you! Looks like we have a problem with rendering on AMD GPU's - fix coming this week hopefully, unless someone opens up a PR sooner!

Experiencing this too on an amd cpu. Any update?

No update yet, I've tried getting decoding working in an Azure VM but have been unsuccessful so far. Would anyone be willing to run some tests with their AMD GPU? crates/video-decode on the separate-video-decoder branch is a binary that will attempt to decode the video at the hardcoded path on the GPU, otherwise falling back to CPU. Using AVHWDeviceType::AV_HWDEVICE_TYPE_D3D12VA should work on Windows - at least it does on the Nvidia GPUs I've tested.

Hi, I can test this, but I don't quite understand what needs to be changed. And I don't understand how to build a Windows version from the source code. But I'm ready to test the version if you build it.

The Windows recording and crash recovery pipeline has been substantially rewritten since this was reported, including fixes for black and green frame output. This specific issue is believed resolved, please re-test on the latest version and open a fresh issue with logs if you still see a black screen.
