I have several live sources that do not have GOV's and they work
perfect with live555. You should not have a problem.....
BTW: Tell Rich Brad says hello :)

Thanks Ross,
I'm now generating the header with the proper visual object sequence
start code and supporting information.
000001B003000001B509000001000000012000C8888007D05841214103
Can I send this information into the MPEG4VideoStreamDiscreteFramer
and/or MPEG4VideoStreamFramer without the next frame info and data?
Or must they be sent together for the first frame to initialize
things?
Also, I wanted to know, can the MPEG4VideoStreamDiscreteFramer and
MPEG4VideoStreamFramer function without the group of VOP start code
(000001B3xxxxxx)? This is defined as optional in the mpeg4 standard.
Thanks
Austin

Hello All,
I having some difficulty getting samples from a live source
(QTCaptureSession) into MPEG4VideoStreamDiscreteFramer via a
DeviceSource.cpp.
The live data does not contain any 000001B3xxx000001B6..... (group
of vop start code) or 000001B0.... (visual object sequence start
code). The only header info in the stream is the 000001B6......
the vop start code.
Then it appears that your data is not standards compliant (or
perhaps, not regular MPEG-4 Video data at all). Are you sure that
it's not something else (e.g., not H.264)?
Can you tell me if the MPEG4VideoStreamDiscreteFramer or
MPEG4VideoStreamFramer can be used with this type of live source?
No.
