Is it possible to receive and decode a user specific udp video stream (udp datagrams contain h264 packets inside them) using a gstreamer pipeline?
Typically such a stream would be packetised using RTP, in which case you can receive it with something like udpsrc caps=application/x-rtp,media=video,encoding-name=H264,clock-rate=90000 ! rtpjitterbuffer ! rtph264depay ! ...
or are you talking about a stream that just contains H.264 packets without any RTP packetisation?
Yes, I mean transmitting h264 packets with a custom udp protocol similar to but different from rtp.
Or this problem can only be solved using ffmpeg libav?
