This may (perhaps) have been an oversight.  The “JPEGVideoRTPSource” code 
basically just implements the code that’s in Appendix B of RFC 2435 (which 
defines the RTP payload format for JPEG video).  I.e., it transforms the 
information that was in the special RTP JPEG header (and quantization tables, 
if present) into a corresponding JPEG image header.  It’s possible that this 
code is incomplete.

If you’re sure about this, feel free to propose a patch to
