[Live-devel] frame alignment

[Rob Casey]

While I haven't examined these frame sizes myself, is it not possible
that you are simply getting B- and P-frames from the MPEG2 stream?  See
http://wiki.multimedia.cx/index.php?title=Frame_Types for a brief
overview of frame types employed within MPEG2 streams.
