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