Comment (by fulinjie):

 Tested with the latest version of MSDK：
 c083a2724b99851af6d69bbb35e3130b39a1f702


 {{{
 $ ffmpeg -i crop-to-container-dims-canon.mov -c:v copy src.h264
 $ ./sample_decode h264 -i src.h264 -i420 -o msdk.yuv
 }}}


 {{{
 ffmpeg -hwaccel qsv -hwaccel_device /dev/dri/renderD128 -v verbose -y -c:v
 h264_qsv -i crop-to-container-dims-canon.mov -vf hwdownload,format=nv12
 -pix_fmt yuv420p -f rawvideo -y dump.yuv -vsync 0
 }}}


 Both msdk.yuv and dump.yuv have garbage in my test.
