Why gitlab and not GitHub? If the intent is on making contribution from new
developers easier, I think the workflow should be where the majority of
developers are actively participating.

Is anyone reviewing patches for qsv? I have two pending patches for
the qsv scale/crop filters. I submitted similar patches for cuda,
videotoolbox, and vulkan already, which were committed.

Searches pkg-config for glslang libraries.
Use libavutil thread.h wrapper rather than directly including pthread.h.

scale filter should also allow negative values
that respect aspect ratio, similar to other scale filters.

Is anyone reviewing videotoolbox or qsv filters? The scale_cuda
version of this patch was merged.

frame crop via the vpp_qsv filter. If no explicit crop
is detected via that filter, AVFrame.crop_* will be used instead.
Removal of vpp_qsv's crop argument may be warranted.

would require
changes in the crop filter, and have unknown downstream effects with
hardware scalers that I have not touched in this change.
My new patch set addresses your first problem.
