Hello Ross,
I was hoping to get an answer on the implementation below so we can
try and figure out why we cannot get the data into live555.
Thank you
Austin

Hello All,
I'm having an issue getting a live MPEG4 video source into Live555,
any help would be great.
This is how I defined my live input;

Thanks Ross,
I'm now generating the header with the proper visual object sequence
start code and supporting information.

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 01B3xxx01B6. (group of
vop start code) or 01B0 (visual object sequence start code).
There is not any large delay (~5 to 10ms) from the call to downstream
call to doGetNextFrame() and the upstream call to
FrameSource::afterGetting(this) in DeviceSource.cpp.
from downstream call to doGetNextFrame()
fPresentationTime.tv_sec=1230780299
fPresentationTime.tv_usec=377538

dura is set for each call, 33366 for 30 frames per sec or 6 for 15
frames per sec, still the data is called for ~ every 1.

fNumVTIRBits=0x00
vop_time_increment=0x00
The above are always zero, could this be the problem?

Thanks Ross, got it.
But I'm this only getting asked for new data ~ every 1.3.
Any ideas?
Thanks

Thanks Ross,

I have modified DeviceSource.cpp deliverFrame to deliverFrame(void
*data, int len) to pass data into it. And in the function follows;
if (!isCurrentlyAwaitingData()) return; // we're not ready for the
data
The call to doGetNextFrame (doGetNextFrame(void *data, int len) in my
code) only happens when data is present. Than in (doGetNextFrame(void
*data, int len) in my code) function I call deliverFrame(data, len);
function passing the data.
But the function deliverFrame(data, len); the if state

Thank you Ross for the quick response.
If our data is separated into audio and video and each is streamed to
our darwin stream server, is the presentation time passed along so
there is not any lip-sync issues? Would it be two unicast stream at
this point or can we put them into one stream?
I was afraid of that. Is there a something we can use for both audio
and video streaming?

Thanks again Ross.

Can the elementary stream for the framedsource consist of audio and

Thanks Ross,
Have you connected the QTCaptureSession output to the input of the
testMPEG4VideoStreamer? If so can you provide some code snippet?
Also, is the DarwinInjector still supported?

Hello,
I’m trying to use (connect) Apples QTKit (QTCaptureSession) to the
input of the testMPEG4VideoToDarwin sample program so I can stream
live events from a video source.
I have testMPEG4VideoToDarwin connecting to my darwin stream server
but I cannot figure out how to get the sampleBuf
