Answer 1

First of all, what platform are you running on?

You can use Live555 only for RTSP/RTP purposes. Live555 however does not contain any decoders, etc.

VLC uses Live555 internally for RTSP AFAIK, but also contains a bunch of other plug-ins, decoders, demultiplexers, etc.

You still need a media framework to handle the media format specific decoding, demultiplexing, rendering etc. On Windows this can be accomplished using DirectShow. In this scenario you can wrap the live555 in a DirectShow source filter and construct a media pipeline. To get the video to display in your Qt application, you would need to investigate how you would parent the DirectShow video renderer window onto your Qt application.

Another cross-platform media framework I am not familiar with is gstreamer.

Edit:

Have you looked at Qt Phonon at all? It looks like they've begun integrating multimedia into the framework, though you'll have to investigate if they support RTSP, and if not, how to get the media data received via Live555 into the Qt media pipeline.

Answer 2

Yes you can use Live555 libraries which is LGPL in your application. Frontend can be implemented using QT, MFC or Java. Live555 provides APIs for establishing RTSP sessions, and for audio/video implementation probably you may need to override few functions. Go through sample applications provided by live555 in its testProgs folder.

If you are making commercial application dont forget to include Live555 license in your releases.
