[Feature]AMF/VCE hardware encoding

[ccxx369]

Supports AV1 HEVC hardware encoding(AMF/VCE) on AMD Radeon RX7000 Series

[Sacred-Shadow]

@Alkl58 AV1 FFmpeg support meanwhile AMD cards. https://trac.ffmpeg.org/wiki/Encode/AV1

Can you add now the av1_amf?

[Sacred-Shadow]

Gibt es hierzu schon eine zeitliche Aussicht?

[32bitx64bit]

1+ OBS has supported AMF AV1 for awhile now, its about time us AMD users get a hardware encoder!

[Alkl58]

AMF AV1 has been added in the latest release.

I am not able to test it, as I don't have a AMD GPU.

I put the following comment in the code, might worth a read for you:

        /*
         * The implementation is pretty questionable
         * There is basically no documentation available online
         * Some unassuring things I found:
         *      - https://trac.ffmpeg.org/ticket/10389 (av1_amf ignores most quality/bitrate settings except for b:v)
         *      - https://trac.ffmpeg.org/ticket/10266 (Issues when using av1_amf to encode a video)*
         *        *does this mean that amd amf only supports 1080p!?
         *      - Supported pixel formats: nv12 yuv420p d3d11 dxva2_vld (no 422/444 ... really?!)
         *  
         *  It's unclear which arguments should be mixed with which.
         */

[Alkl58]

Could you try manually executing the following from CMD?: ffmpeg.exe -y -i "G:\视频\Unknown.mp4" -an -sn -map_metadata -1 -pix_fmt yuv420p -c:v av1_amf -quality speed -rc cqp -qp 24 "C:\Users\My-On\AppData\Local\Temp\NEAV1E\MIpQgKmbOnPUXpy\Video\000000.ivf (You may have to change output path)

If you are willing to help, I would like to send you a zip file with a bunch of tests you can execute.

[Alkl58]

Are you sure that the input file G:\视频\Unknown.mp4 exists?

[ccxx369]

yes，of course

[Alkl58]

Does the following work: ffmpeg.exe -y -i "G:\视频\Unknown.mp4" -pix_fmt yuv420p -c:v libx264 -crf 22 outtest.mp4?

Because the error message clearly states that it couldn't open the input file. (Maybe permission issue?)
