My understanding is the DVD specification has provision to support LPCM audio sampled at 48K through private extension. I would like to know if the vobStreamer sample application will be able to process and send such stream through RTSP/RTP

No, but it could easily be modified to do so. Streaming PCM audio is easy; just use a "SimpleRTPSink" (instead of a "AC3AudioRTPSink"). See, for example our "testWAVAudioStreamer" demo application.

One thing to watch out for: PCM data streamed within RTP packets must be big-endian. If, instead, your source PCM data is in little-endian order, then you will need to add a byte-swapping filter before streaming it. (There is also an example of this in the "testWAVAudioStreamer" code.)
