You can probably reduce BANK_SIZE, but it should be at least as large as
the largest possible MPEG-4 video frame that you expect to see.
A reminder, however: If your application's input source is *discrete*
MPEG-4 video frames (i.e., each time you read from the input source, you
get exactly one MPEG-4 frame), then you can use a
"MPEG4VideoStreamDiscreteFramer" instead of a
"MPEG4VideoStreamFramer". The implementation of
"MPEG4VideoStreamDiscreteFramer" does *not* use a "StreamParser", and uses
a lot less memory than "MPEG4VideoStreamFramer".
