It is supported on AMD Radeon CPU 5000 series and higher and RX 6000 series and higher graphics cards. The average transcoding speed improves up to 30%. This patch is tested on AMD Ryzen 5 7600X + AMD GPU RX6700XT. To enable this feature, you need to select the hwaccel AMF input and output as in the example below: ffmpeg.exe -hwaccel amf -hwaccel_output_format amf -extra_hw_frames 33 -i input.mp4 -c:v hevc_amf -smart_access_video 1 -y output.mp4 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel
