[FFmpeg-user] avfilter: hwoverlay

As now we have many filters compatible with the GPU, and in particular “scale” filters. So I think we need a filter like “hwoverlay” or “overlay_cuda/_qsv/etc.”.

With this kind of filter we can do a PiP using only a GPU pipeline:

- GPU decoder --> spplit (hw) --> hwscale --> hwoverlay --> GPU encoder

In fact, I feel it’s not too complex to do.

What you think?
