Which specific patch are you referring to?

If you are referring to the patch that's mentioned here
	http://lists.live555.com/pipermail/live-devel/2007-July/007245.html
then that has already been implemented, except for a sanity check in 
the function "JPEGVideoRTPSink::specialHeaderSize()".  That can be 
fixed by adding the line:

	if (source == NULL) return 0; // sanity check

at line 109.  This will be included in the next release of the software.

(However, this really shouldn't be necesary, because people should 
not really be calling these functions on "JPEGVideoRTPSink" objects 
if they don't yet have a source to read from.)
