[FFmpeg-devel] [PATCH] libavfilter/qsvvpp: change the output frame's width and height

[wenbin.chen at intel.com]

From: "Chen,Wenbin" <wenbin.chen at intel.com>

qsvvpp align the width and height with 16, and that may lead to error.
For example, when we use qsvvpp to resize frame to 1080p, qsvvpp will
align frame to 1088 which is different from the height of
encoder (1080) and this will be treated as resolution change. Now I 
assign the out_link's w/h to output
frame to overwrite the w/h got from hw_frame_ctx.
