mpegvideoparse: Handle Sequence Display Extension
...
Change the way the pixel-aspect-ratio is computed by
interpreting the sequence header aspect ratio info
as MPEG-1 values until a sequence extension or
sequence display extension is seen, and then updating
the sequence header struct accordingly.
Fixes incorrect anamorphic display on some MPEG-2 (DVD)
sequences.

* delaying the input parsing (since we would need the next incoming NALU
in order for the parsing code to detect the next start code)
