Comment (by oromit):
There's not much to bisect here. This probably happens since the change
from copying the frame to directly handing through the mapped cuvid
surface, making the decoder dependend on the other parts of the chain
releasing frames fast enough. The logic to calculate this does not seem to
be flawless with interlaced content. I suspect it's a paff vs. mbaff issue
as well.
You can always increase the buffer size by bumping up extra_hw_frames
until the chain runs through.
