A Gstreamer wrapper around Cisco VQE Client which implements RFC 3550 (RTP) and RFC 4588 (RTP Retransmission). It integrates VQE-Client into Gstreamer such that it can be autoplugged to handle SDP files.
Two elements are provided:
- vqesrc - A Gstreamer source element which takes the contents of an SDP file as a property and streams video from the referenced multicast groups.
- vqesdpdemux - Acts as a "demuxer" which "converts" SDP files to mpeg-ts streams. vqesdpdemux will be autoplugged by Gstreamer to handle SDP files which means decodebin will use it when it encounters an SDP file.
Read SDP file from file, connect to the multicast group contained with and stream mpeg-ts to file:
gst-launch-1.0 filesrc location=my-channel.sdp \ ! application/sdp \ ! vqesdpdemux \ ! filesink
Demonstrating gstreamer decodebin integration: read SDP file over http and display it to screen:
gst-launch-1.0 playbin uri=http://uri.of/my-channel.sdp
This is essentially an integration project between Cisco VQE client and Gstreamer 1.0 so these are gst-vqe's dependencies:
pkg-config is used to locate these dependecies on your system.
gst-vqe is a standard autotools package. To build execute:
./autogen.sh make make install
- Don't assume the stream will be MPEG-TS, adjust caps based upon what is in the header file.
gst-vqe is dual licensed BSD/LGPL2+ for consistency with VQE and Gstreamer respectively. See LICENSE.BSD and LICENSE.LGPL2 for more information.
