Add AMD encoding option with ffmpeg (possible solution)

Open Bercraft opened this issue 3 years ago • 0 comments

Now the encoding is done only via or CPU or Nvidia GPU, i found a way to make possible for amd users to use thier gpu (maybe). Ffmpeg has the encoder for amd GPU is h264_amf and hevc_amf.

Thank you for your work.

The usable option are :

h264_amf AVOptions: -usage E..V.... Encoder Usage (from 0 to 3) (default transcoding) transcoding E..V.... Generic Transcoding ultralowlatency E..V.... lowlatency E..V.... webcam E..V....

Ad exempla -> ffmpeg -i input.mkv -c:v hevc_amf -rc cqp -qp_p 0 -qp_i 0 -c:a copy output.mkv would be lossless
