You're thinking about this the wrong way. "doGetNextFrame()" gets called
automatically (by the downstream, 'transmitting' object) whenever it needs a
new NAL unit to transmit. So you should just deliver the next NAL unit (just
one!) whenever "doGetNextFrame()" is called. If your encoder can g
Hi Ross,
Thanks a lot for your answers.
I have some comments/additional questions, inline in green below.
Many thanks for your help!

Hi Ross,
Thanks for your comment. Here is the implementation of doGetNextFrame() in my
class (which is indeed derived from FramedSource):
void CAvSource::doGetNextFrame()
{
// Forward all frames in the input AV buffer
while (getTopMetadata() != NULL)
{
deliverFrame();
}
}
Hello,
I am trying to build an RTSP server using liveMedia to stream H.264 in real
time from a live encoder. In essence, as soon as I try to connect with VLC,
liveMedia abort()s with the following message:
FramedSource[0xbe838]::getNextFrame(): attempting to read more than once at the
same time
Dear Ross,
Because your codec is MP3, you definitely *do not* need to reimplement the
"getAuxSDPLine()" virtual function. I.e., if you have such a reimplementation,
then you should remove it.
Many thanks for these details, that's enlightening!
Our RTP output code - in this case, the "MPEG1o
Dear Ross,
I have another question about FramedSource::doGetNextFrame(). Does this
method requires the actual MP3 frame to be returned, or the MP3 frame
encapsulated as required by the chosen RTP profile (14 in my case)?
Thanks a lot for your help!
Best regards,
Fabrice

Dear Ross,
We implemented a class based on OnDemandServerMediaSubsession, and it
uses an apparently widely used trick in live555 to get the "SDP lines".
It plays the stream into a "dummy" RTP sink to get those lines and then
stops the stream. That's where things were going wrong, because the R
Dear Ross,
Before you do this, you should first just add a
"MP3AudioFileServerMediaSubsession" with the MP3 file - just to make sure that
this (an audio subsession with data coming from a file) works OK for you.
Thanks for the tip!
I just tried it instead of our custom subsession class, and it
Hello everyone,
I hope somebody could point me to some directions where to investigate.
I am trying to modify an existing RTSP server based on live555. It
streams live video without problems, and I have to add live audio
sub-streams for each video streams.
As a first step, I wanted to stream
