[AAC Company Private] gstreamer copy h-264 camera output to network

[Olivier Crête]

Hi,

It seems you want something RTP based. You can start with just rtpbin
(look at the examples in the rtpbin doc). Or if it's client-server on a
local network, maybe you can use RTSP (gst-rtsp-server + rtspsrc), or
if you want to go to an internet server, then maybe you want to look at
WebRTC, and then use webrtcsink with the appropriate signaler for the
server you are using.
