[FFmpeg-devel] [PATCH 3/3] libavutil/hwcontext_opencl: fix a bug for mapping qsv frame to opencl

[Chen, Wenbin]

> mfxHDLPair was added to qsv, so modify qsv->opencl map function as well.
> Now the following commandline works:
> 
> ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 \
> -init_hw_device qsv=qs at va -init_hw_device opencl=ocl at va -
> filter_hw_device ocl \
> -hwaccel qsv -hwaccel_output_format qsv -hwaccel_device qs -c:v h264_qsv
> \
> -i input.264 -vf
> "hwmap=derive_device=opencl,format=opencl,avgblur_opencl, \
> hwmap=derive_device=qsv:reverse=1:extra_hw_frames=32,format=qsv" \
> -c:v h264_qsv output.264
