But maybe I'm wrong? I'll poke around. I tried Capturinha (https://github.com/kebby/Capturinha), but couldn't make it work for lossless - it might be an easy code change though. I also tried OBS and almost succeeded. The only remaining problem with OBS is the colour space conversion which is not lossless. More precisely, trying NV12 gives me wrong colours and trying anything else gives me "Encoding Overloaded" for no apparent reason (all performance indicators, CPU and GPU look mild). >> My only theory is that GPU memory might be getting full I checked, it wasn't. >> Maybe I should use hevc_nvenc with lossless setting Tried, ran into the same problem as with hwdownload->utvideo. Maybe something about the grabber? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
