[FFmpeg-devel] [PATCH] avutil/hwcontext_d3d11va: Support DXGI_FORMAT_B8G8R8A8_UNORM encoding

[you74674 at gmail.com]

From: you74674 <you74674 at gmail.com>

Support using DXGI_FORMAT_B8G8R8A8_UNORM format ID3D11Texture2D
texture as AVCodecContext->hw_frames_ctx for encoding.
AV_PIX_FMT_0RGB32 is used here because in libavcodec/nvenc.c, it is
mapped to NV_ENC_BUFFER_FORMAT_ARGB, which is mapped to
DXGI_FORMAT_B8G8R8A8_UNORM in sample code from NvCodec.
