Sending video over the net

Sending video over the net

Jitter offers two objects for sending high quality video over the internet for video conferencing and remote (telematic) performances, but I have found some issues with both and maybe someone has a solution to these:

jit.net.send and receive seems to use TCP instead of RTP (Real-time Transport Protocol) or RTCP. I think that RTP would be much more effective for sending video, especially for my application where transmission speed is the number one issue. TCP works OK for small videos, but when i try to send bigger videos, the stream gets all clogged up and jitter complains about dropped matrices.

The other object that I’ve found is jit.qt.broadcast. This uses RTSP (Real-Time Streaming Protocol). I have not put as much time into this object, but there does not seem to be any controls to adjust compression settings, which I could tweak in jit.qt.grab with the message “settings” to reduce the latency of the video compression.

Any ideas or suggestions? Thanks.

I think RTSP is the way to go, it’s nice and easy. You could always check out something like Quicktime Broadcaster and see if that gives you better control over your source.
