[Live-devel] ONVIF support in Live555

I'll support this only if it ends up being adopted by the IETF (the 
organization that standardizes RTP payload formats and header 
extensions).  In particular, "ONVIF" will need to persuade the IETF 
(in particular, the IETF's AVT working group) that the right way to 
support 'enhanced' JPEG-over-RTP is via a RTP header extension using 
the existing RFC 2435 payload format, rather than adopting a new RTP 
payload format for JPEG-over-RTP.


>Particularly, do you plan to support JPEG over RTP enhanced headers?

Someday we will support RTP header extensions (though not necessarily 
this particular application of them (see above)).

More generally, though, I'm curious about why people are still 
interested in JPEG-over-RTP, especially with very large JPEG images. 
JPEG is a *terrible* codec to use for video; it doesn't have any of 
the inter-frame prediction/compression features that real video 
codecs have.
