RFC 2435 - and our sending/receiving implementation 
("JPEGVideoRTPSink"/"JPEGVideoRTPSource") - *does* support 
non-standard quantization tables (they are included in JPEG header in 
the RTP packet).

To stream such a source, you must implement a subclass of 
"JPEGVideoSource" class, and, in particular - because you have 
non-standard quantization tables - implement the 
"quantizationTables()" virtual function.
