Comment (by jkqxz):
I've seen this too a few times - seems to be something in libavfilter to
do with format negotiation around the hw* filters, but I've never pursued
it beyond that. You can work around it by specifying the formats
explicitly (i.e. add 'format=yuv420p' to the end of your filter graph).
