Hi Ross,<br>
<br>
I'm currently updating our RTSP client (based on liveMedia), to use
your asynchronous API.<br>
The client is being used within a simple GTK application, so as you
mentioned in the FAQ, I have to subclass to use GTK's event loop
instead of your native loop.<br>
So I did a simple subclass of BasicTaskScheduler, that I named
EventScheduler.<br>
<br>
The only method I'm re-implementing is 'doEventLoop', so I can let GTK
event loop handle the 'SingleStep' calls.<br>
It works fine for the first call (DESCRIBE), but after then, it
crashes...I provided you a backtrace afterwards.<br>
<br>
I'm pretty sure I've made a wrong (or incomplete) subclass, but I tried
to match openRTSP source as close as possible.<br>
By the way, when I replace my custom TaskScheduler by the basic one
(BasicTaskScheduler), problem still occurs.<br>
<br>
Thanks for you insights !<br>
<br>
Best regards,<br>
Guillaume.<br>
<br>
PS : I'm using the latest liveMedia sources (2010.09.10)<br>
