highlighted artifacts.

Testing with mpv like -

mpv --hwdec=vaapi --vo=vaapi --vf=vavpp:deint=motion-adaptive ....

Produces artifacts which look like old buffers/pixels around the edges of
things get replayed in their old position if eg. the camera is panning.

The artifacts only appear in one field so those highlighted in the attached pic
would flash on/off if frame stepping with mpv.

The artifacts do not vary on a given sample whether it's frame stepped/slow
mo/normal speed.

Without pp or with deint=bob output is OK. (testing h264 as mpeg2 has it's own
issues).

Using motion-adaptive deint via vdpau does not have the issue.

Only mpv tested as I failed so far to get gstreamer to use pp.
