This is fairly common. The output of a decoder is often bigger then what
should be displayed. If downstream sink supports it, you shall attach
crop meta to you buffers (1.X). videoparse won't handle that, so I doubt
it's the ideal solution.

There used to be vaapidownload element to do what you are trying to do.
If that still exist, it would prevent having two pipelines, and also
make sure all caps and meta are passed correctly.
