This page presents some examples of GstWebRTC using OpenWebRTC's signaler.
Contents
Only Audio
Opus
Unidirectional
Example: In this example we use webrtcsink to send an audio stream and webrtcsrc to receive the audio stream.
The following pipeline will send periodic ticks:
gst-launch-1.0 webrtcsink start-call=true signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=8 ! audioconvert ! audioresample \
! queue ! opusenc ! rtpopuspay ! web.audio
The following pipeline will receive the periodic ticks:
gst-launch-1.0 webrtcsrc start-call=false signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web web.audio ! rtpopusdepay ! opusdec ! audioconvert ! \
alsasink async=false
When executing the two previous pipelines, you should be able to listen the ticks in the receiving computer.
Bidirectional
Example: In this example we use two webrtcbin elements, each sends an audio stream and receives each other audio stream.
The following pipeline will send a white noise audio stream and receive the ticks audio stream sent by the next pipeline. This pipeline starts the call.
gst-launch-1.0 webrtcbin start-call=true signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=5 ! audioconvert ! \
audioresample ! queue ! opusenc ! rtpopuspay ! web.audio_sink web.audio_src ! rtpopusdepay ! \
opusdec ! audioconvert ! alsasink sync=false async=false
The following pipeline will send ticks audio stream and receive the white noise audio stream sent by the previous pipeline. This pipeline joins the call.
gst-launch-1.0 webrtcbin start-call=false signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web audiotestsrc is-live=true wave=8 ! audioconvert ! \
audioresample ! queue ! opusenc ! rtpopuspay ! web.audio_sink web.audio_src ! rtpopusdepay ! \
opusdec ! audioconvert ! alsasink sync=false async=false
When executing the two previous pipelines, you should be able to listen the ticks and the white noise.
Only Video
H264
Unidirectional
Example: In this example we use webrtcsink to send a video stream and webrtcsrc to receive the video stream.
The following pipeline will send a color bars h264 video stream:
gst-launch-1.0 webrtcsink start-call=true signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
x264enc key-int-max=2 ! rtph264pay ! queue ! web.video
The following pipeline will receive the video stream and display it:
gst-launch-1.0 webrtcsrc start-call=false signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web web.video ! rtph264depay ! avdec_h264 ! videoconvert \
! ximagesink async=true
You should be able to see a video pattern similar to Fig.1.
Bidirectional
Example: In this example we use two webrtcbin elements, each sends a video stream and receives each other video stream.
The following pipeline starts the call:
gst-launch-1.0 webrtcbin start-call=true signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
x264enc key-int-max=2 ! rtph264pay ! queue ! identity silent=false ! web.video_sink web.video_src \
! rtph264depay ! avdec_h264 ! videoconvert ! ximagesink async=true
The following pipeline joins the call:
gst-launch-1.0 webrtcbin start-call=false signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
x264enc key-int-max=2 ! rtph264pay ! queue ! identity silent=false ! web.video_sink web.video_src \
! rtph264depay ! avdec_h264 ! videoconvert ! ximagesink async=true
You should be able to see two windows with a video pattern similar to Fig.1.
Vp8
Unidirectional
Example: In this example we use webrtcsink to send a video stream and webrtcsrc to receive the video stream.
The following pipeline will send a color bars vp8 video stream:
gst-launch-1.0 webrtcsink start-call=true signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web videotestsrc is-live=true ! queue ! videoconvert ! \
vp8enc ! rtpvp8pay ! queue ! identity ! web.video
The following pipeline will receive the video stream and display it:
gst-launch-1.0 webrtcsrc start-call=false signaler::server_url=http://webrtc.ridgerun.com:8080 \
signaler::session_id=1234ridgerun name=web web.video ! rtpvp8depay ! vp8dec ! videoconvert ! \
