No, but without them a lost packet will lose the whole frame. You are setting the M bit for end of frame right?


If you check the other box (RFC 2035 compatible) it doesn't generate restart markers.

I don't have OS X server running here, which is apparently required for QTSS. Will something else do this, like the Darwin source?

I meant QTSS in the generic sense - anything that reads hinted movies, including QTSS, DSS, Entera & Real8



I'm skipping all my tables and markers and starting with my scan line data.

Good.


All that's supposedly what I'm doing. The RTSP negotiation seems to be happy, then I send my JPEG data (starting with the first scan line) using code verbatim from Appendix C of rfc 2435 (but no restart header). I'll play around with it some more and see if Darwin can play my QTPlayer-generated hinted jpeg movie.

If you keep having troubles, give me an rtsp URL and I can look at your packets and see why we are rejecting them
