|
|
|
|
* This elements pass RTP packets along unchanged and appear as a RTP
|
|
|
|
* payloader element to the outside world.
|
|
|
|
*
|
|
|
|
* This is useful, for example, in the case where you are receiving RTP
|
|
|
|
* packets from a different source and want to serve them over RTSP. Since the
|
|
|
|
* gst-rtsp-server library expect the element marked as `payX` to be a RTP
|
|
|
|
* payloader element and assumes certain properties are available.
|
|
|
|
*
|
|
|
|
* ## Example pipelines
|
|
|
|
*
|
|
|
|
* |[
|
|
|
|
* gst-launch-1.0 rtpbin name=rtpbin \
|
|
|
|
* videotestsrc ! videoconvert ! x264enc ! rtph264pay ! rtpbin.send_rtp_sink_0 \
|
|
|
|
* rtpbin.send_rtp_src_0 ! udpsink port=5000
|
|
|
|
* ]| Encode and payload H264 video from videotestsrc. The H264 RTP packets are
|
|
|
|
* sent on UDP port 5000.
|
|
|
|
* |[
|
|
|
|
* test-launch "( udpsrc port=5000 caps=application/x-rtp, ..." ! .recv_rtp_sink_0 \
|
|
|
|
* rtpbin ! rtppassthroughpay name=pay0 )"
|
|
|
|
* ]| Setup a gstreamer-rtsp-server using the example tool, it will listen for
|
|
|
|
* H264 RTP packets on port 5000 and present them using the rtppassthroughpay
|
|
|
|
* element as the well-known payloader pay0.
