If input frames have times like this:

pts=1 duration=33333
pts=2 duration=33333
pts=3 duration=33333

then the MFT changes the pts to be the previous pts + the previous frame
duration. Web Codecs requires the pts to be untouched.

Somehow this fails for me, only for vp9.

It's already implemented on macOS PEM.
