5f24c50890 amfenc: Fix for full PA queue 
Fixes AMF_INPUT_FULL errors with pre-analysis (PA) enabled.
Added wait and poll encoder output to free up internal buffers
before submitting new frames.
Improves stability and performance by accounting for encoder and
analysis stage queue limits (incl. lookahead buffering).

Reproduce:
ffmpeg.exe -y -r 60 -f lavfi -i testsrc=rate=60:size=3840x2160
-t 10 -pix_fmt yuv420p -an -c:v av1_amf -preset:v high_quality
-profile:v main -quality:v high_quality -usage:v high_quality

079110238a avcodec/amfenc: add smart access video option 
This commit adds option for enabling SmartAccess Video (SAV)
in AMF encoders. SAV is an AMD hardware-specific feature which
enables the parallelization of encode and decode streams across
multiple Video Codec Engine (VCN) hardware instances.

fb4dd4b6f4 avcodec/amfenc: Fixes the color information in the output. 
added 10 bit support for amf hevc.

before:

command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file.mkv -an -c:v h264_amf res.dx11_hw_h264.mkv
output -  Format of input frames context (p010le) is not supported by AMF.
command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file -an -c:v hevc_amf res.dx11_hw_hevc.mkv
output -  Format of input frames context (p010le) is not supported by AMF.

after:

command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file -an -c:v h264_amf res.dx11_hw_h264.mkv
output -  10-bit input video is not supported by AMF H264 encoder
command - ffmpeg.exe -hide_banner -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i test_10bit_file -an -c:v hevc_amf res.dx11_hw_hevc.mkv
output -  10bit file

v2 - lost line returned in ff_amf_pix_fmts
v3 - fixes after review
v4 - extract duplicated code, fix incorrect processing of 10-bit input for h264
v5 - non-functional changes after review

2fb764e1f3 lavc/amfenc: Add hardware config metadata 
Without this metadata section the ffmpeg utility thinks that the AMF encoder
does not support input from D3D11 and DXVA2 hardware surfaces, causing
hardware pipelines to fail.

Fixes #8953.

827d6fe73d avcodec/encode: restructure the core encoding code 
This commit follows the same logic as 061a0c14bb, but for the encode API: The
new public encoding API will no longer be a wrapper around the old deprecated
one, and the internal API used by the encoders now consists of a single
receive_packet() callback that pulls frames as required.
