[FFmpeg-devel] [PATCH v2 00/22] clean-up QSV filters

[Haihao Xiang]

This patchset clean up scale_qsv and deinterlace_qsv filters, and take
the two filters as the special cases of vpp_qsv, so vf_scale_qsv.c and
vf_deinterlace_qsv.c can be deleted from FFmpeg. In addition, a few
small features are added in this patchset.
