I don't quite understand what I should test with x265. > I was hoping that that x265_hidepth will allow you to speed up compilation a bit by building 8bpc only x265, so if you enabled this parameter x265_10bit profiles should thrown error at you. > Another thing, I wanted to create encoding presets with AMD's AMF > framework (the equivalent of Nvidia's NVENC), since it's open source and > has been separated from amdgpu-pro, but I can't enable it in the > ./configure phase. Any idea how to do this? > Same generic mechanism: export FFMPEG_EXTRA_CFG=" --enable-amd " (not literally, look at what ffmpeg --configure demand) for me on ffmpeg 8.0 configure it says --disable-amf disable AMF video encoding code [autodetect] so it a bit strange that you do not have it autodetected? I assume you installed headers ... then export export EXTRA_LIBS="-lamdlib -lWhatever" (you already have opencl libs there. > One last thing, not important, just something I'm curious about: > When I load an av1 media file, I get this warning: > > "Decoder libdav1d does not support device type vulkan. > HW device init failed, using SW decode" > > I wanted to try disabling dav1d and going back to the classic libaom_av1 > to test whether hardware-accelerated Vulkan had reached or exceeded the > performance of dav1d (which is very fast but software-based).
