[Asterisk-video] app_rtsp: asterisk hangup

[Thomas Frieling]

Hi Klaus!

Sounds pretty convincing to me... But if this is really the case, then
we should definitely handle this problem before it occurs: Maybe we can
check the queue's size before sending a package and decide to skip some
packages to synchronize the outgoing stream.
This would help keeping sound and video synchronous and it would prevent
the "exceptionally long queue" error.

What do you think about this? Would it be hard to implement?

Greetings,
Thomas
