However a more likely cause of problems
like this is that you are setting "fPresentationTime"
incorrectly for one or both of your audio and video substreams -
so they end up being non-synchronized at the receiver (VLC) end.</div>
<div><br>
</div>
<div>For each frame delivered by your input source,
"fPresentationTime" must be set properly, and must be aligned
with 'wall clock' time - i.e., the time that you'd get by
calling "gettimeofday()".</div>

<br>
I do set fPresentationTime using gettimeofday() in my implementation
of DeviceSource. It's the same class for both video and audio.<br></div></blockquote><div><br></div></div>That's good. Nonetheless, the symptoms you describe are consistent with bad presentation times, so - just to be sure - I suggest that you try running "testRTSPClient" as your client application, and check that the frame presentation times are sane.<div><br></div><div>Also, because you report that you can stream video-only, but have a problem only when you try to stream both audio and video, I suggest that you try streaming audio-only.</div><br><br><div apple-content-edited="true">
