[FFmpeg-devel] [PATCH] avutil/hwcontext_d3d11va: enable D3D11_RESOURCE_MISC_SHARED for texture

[Tong Wu]

Add D3D11_RESOURCE_MISC_SHARED flag for texture to make it shareable.
This can fix the green frames issue when mapping from d3d11va to opencl.
Sample command line: ffmpeg.exe -hwaccel d3d11va -hwaccel_output_format
d3d11 -i input.264 -vf
"hwmap=derive_device=opencl,format=opencl,hwdownload,format=nv12" -c:v
libx264 output.mp4
