    Seems like it would probably be possible to do something inside VAAPI in the driver? Maybe not, though, since they haven't.

      It would be weird if hardware starts decreasing dimension values, becasue that's super confusing but increasing is OK, because as above it can be clipped.
      Sure, you can crop it with ffmpeg, but then you have to reencode it with something, obviously not VCN because that'd just put the padding back. And in that case why not just use that alternate encoder (presumably SVT-AV1) to begin with?

      The only way a workaround would be possible is if the target container format has some way to specify a crop in the metadata. I don't know which ones (if any) do.
