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?
