That's interesting stuff. I also dabble with ffmpeg and "obs-studio" [info: OBS 26.1.2-2 (linux)] related to Twitch. Not that I'm a "streamer", but I enjoy goofing around with the technology. I was trying to live-encode things with a raspberry pi to watch streams via a chromecast, but it generally proved to be too intense for the 4GB Pi4 (even using omx/omx-rpi) so I just use a combo of youtube-dl & ffmpeg to "-copy" VODs in 30m chunks to watch them 'on-demand'; I'm not an interactive Twitch person, so syncing up w/ streamers and chat isn't really a thing for me. I found your ffmpeg example command here: https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidi... and attempted to experiment with it using Arch's provided ffmpeg and one that I'd just compiled from source. Neither work using that command as it's laid out, I can simply use "-hwaccel cuda" and NOT have "-hwaccel_output_format cuda" present and it completes w/o massive errors. What that changes, I'm not 100% sure and it might not make a difference unless people compare converting the same video files. Back to obs-studio, I already have it on my box w/ the 2070 super in it and things seem fine there, at least if I have a terminal up and run "obs" from within - it seems to be using NVENC w/o issue. This was the case for Arch's /usr/bin/ffmpeg and my git /usr/local/bin/ffmpeg install (adjusting PATH and LD_LIBRARY_PATH). Firing it up I see this: ... info: Loading up OpenGL on adapter NVIDIA Corporation GeForce RTX 2070 SUPER/PCIe/SSE2 info: OpenGL loaded successfully, version 3.3.0 NVIDIA 460.80, shading language 3.30 NVIDIA via Cg compiler ... info: NVENC supported I can record a video of my webcam and browser (w/ a YT video playing in it) w/o issue and it seems just fine. Again, I don't know if this _proves_ anything positive or negative, but I'm always interested in learning a bit more about this stuff and the expectations around how it's supposed to work compared to the expectations of others (who know more about it than I do).
