If I get a succession of frames with no valid got_picture_ptr then effectively my decoding stream stalls until I get a valid picture again. I'm assuming that it's ultimately loss of data that causes the issues? If this is the case then there's not much I can do about it, which is fine.

One of the causes for got_picture to be FALSE without packet loss
could be that the stream has unexpected B-frames.
