* refactoring of live555 module.
- less code duplication
- automaticly try HTTP tunneling if describe fails
- upon authentication failure, ask for a new user/passwd and try again (untested due to lack of a rtsp source)
- fix a bug with adding tracks introduced in [16114]
- fix a bug closing the RTSPClient
- disabled the QT VoD detection because it's unreliable like hell.
TODO:
- test with a WMS RTSP session
- test against a paswd. protected RTSP session
- find a better way for error communication with live (parsing random strings is so 1990)
- find a way to relay Control() calls to a subdemux (for time/pos in TS)
- add the HREF support of the 0.8.5-href branch
- better flushing etc. during the PAUSE (ideas anyone?)
