[FFmpeg-devel] [PATCH] fftools/qsv: add extra_hw_frames support

[Zhong Li]

Currently extra_hw_frames can't be applied to qsv since it
doesn't call function avcodec_get_hw_frames_parameters().

Give an option to fix ticket #7261 though it is not a perfect soultion
(allocate the minimum pool size internally and automatically).
