Hello! By default connection is TCP, but if I heave only UDP rtsp. How I may specify manually UDP protocol to connect rtsp point?

P.S. 'thnx for good project'

Hi,

Not sure what you mean..

When you connect with libValkka to an IP cam, it starts negotiating with the camera using RTSP protocol, which uses TCP sockets
Once that negotiation is over, the video streaming is done over UDP sockets

This is the standard way of doing things with IP cameras.

What do you want to achieve? You want the video streaming to use TCP sockets as well?

Like in ffmpeg key -rtsp_transport (udp/tcp)

elsampsa commented 4 years ago

ok.. The normal behaviour (as I just explained), would correspond to

-rtsp_transport udp

If you wan't to do

-rtsp_transport rtsp

When you construct your LiveConnectionContext in python (like in here), pass it the parameter request_tcp = True

The level-1 API has been contructed in the cpp side, and is available here
