The decoder is responsible for setting the correct date in the picture_t.

I am not sure if it has to return pictures in chronological order or not. But 
either way, you can request more than one picture buffer at a time.

However, the number of picture buffers is limited by the underlying video 
output, at least if direct rendering is used.
