data only. Here we have a clarification here. Do we need to create a separate
class called MP4VideoStreamFramer derived from FramedSource, which does the job
of constructing the RTP packet from the buffer and send the packet to the
client. Or We can use the existing classes (MPEG1or2VideoStreamFramer or MPEG4VideoStreamFramer)
