The decoder seems to be able to output both video/x-mixvideo-private and some
kind of video/x-va. The main difference seems to be that in 0.10.35 the decoder
did a get_allowed_caps() on the source pad after getting the first buffer:

gst_pad_get_allowed_caps:<mixvideodecoderh2640:src> getting allowed caps
gst_pad_get_allowed_caps:<mixvideodecoderh2640:src> allowed caps

and in 0.10.36:

gst_pad_get_allowed_caps:<mixvideodecoderh2640:src> no peer

which makes it default to output video/x-va, which is where things start
failing then.
