[FFmpeg-devel] [PATCH 01/10, v3] avutil: add hwcontext_amf.

[Dmitrii Ovchinnikov]

DX12 and Vulkan native encoders will expose less features compare to AMF,

at least in foreseeable feature. The missing features include low latency,

PreAnalysis including look-ahead etc. AMF context on Windows allows fully

enable SAV - ability to utilize VCNs in dGPU and APU in a single session.

AMF components including encoder and decoder has some internal optimizations

in the area of memory access for APUs that are not available in standard

3D APIs.

Eventually specialized multimedia AMD cards could be added seamlessly to

FFmpeg with AMF integration.

AMF FSR(VSR) includes YUV version with focus on videos which is not

available in AMD FSR aimed for gaming.

More advanced filters that are not available in standard 3D APIs are coming.
