However, when I list the supported encoder settings using ffmpeg -h encoder=hevc_nvenc (output of command pasted below), even though it supports main10, no 10-bit pixel format is supported: Supported pixel formats: yuv420p nv12 p010le yuv444p p016le yuv444p16le bgr0 rgb0 cuda d3d11. Using CUDA (on a Pascal 1050 Ti), I expect the corresponding command to be ffmpeg -i input.mkv -pix_fmt yuv420p10le -c:v hevc_nvenc -profile:v main10 -cq 21 out.mkv. Without hardware acceleration, a typical command would be ffmpeg -i input.mkv -pix_fmt yuv420p10le -c:v libx265 -crf 21 -x265-params profile=main10 out.mkv.
I am trying to encode a 10-bit H.265 video from a 8-bit H.264 source using ffmpeg with CUDA hardware acceleration.
