Dear Team,<br>
<br>
we are using *testOnDemandRTSPServer.cpp *for the Live Video streaming.<br>
So, in the input I am giving H.264 Encoded fifo to the compile binary using<br>
this testOnDemandRTSPServer.cpp and I am getting RTSP URL for the Video<br>
streaming.<br>
This is working fine.<br>
<br>
Now,we want to add the Audio with Video in the Live streaming. For the<br>
Audio I have one AAC-LC Encoded fifo.<br>
But to stream Audio and Video fifo in time sync, I am not able to find any<br>
option in the testOnDemarRTSPServer.cpp file.<br>
<br>
It would be really helpful if you can provide any example/reference in<br>
which, I give the Audio fifo and video fifo as input and then I get the URL<br>
for the streaming.<br>
So, I can do the audio and video streaming smoothly.<br>
<br>
Note: we have separate fifo for the Audio and Video.<br>
<br>
Thank you so much in advance for your kind support.<br>
<br>

<br>
Streaming audio+video is easy: Just call ?addSubsession()? twice - once for the video source, another time for the audio source. (So that your ?ServerMediaSession? object contains two ?ServerMediaSubsession? objects - one for the video, one for the audio.)<br>
<br>
However, for audio/video synchronization to work properly, each source (video and audio) *must* generate proper ?fPresentationTime? values for each frame, and these *must* be aligned with ?wall clock? time - i.e., the same time that you?d get if you called ?gettimeofday()?.<br>
