| − | This page | + | This page presents some GstWebRTC audio examples using OpenWebRTC. |
| − | == | + | =Opus= |
| − | < | + | ==Unidirectional Elements== |
| − | + | ===Example=== | |
| − | + | In this example we use webrtcsink to send an audio stream and webrtcsrc to receive the audio stream. | |
| − | + | ||
| − | + | ====Send pipeline==== | |
| − | + | The following pipeline will send periodic ticks: | |
| − | </ | + | <syntaxhighlight lang='bash'> |
| + | gst-launch-1.0 webrtcsink start-call=true signaler=GstOwrSignaler 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 | ||
| + | </syntaxhighlight> | ||
| + | |||
| + | ====Receive pipeline==== | ||
| + | The following pipeline will receive the periodic ticks: | ||
| + | <syntaxhighlight lang='bash'> | ||
| + | gst-launch-1.0 webrtcsrc start-call=false signaler=GstOwrSignaler signaler::server_url=http://webrtc.ridgerun.com:8080 \ | ||
| + | signaler::session_id=1234ridgerun name=web web.audio ! rtpopusdepay ! opusdec ! audioconvert ! \ | ||
| + | alsasink async=false | ||
| + | </syntaxhighlight> | ||
| + | |||
| + | When executing the two previous pipelines, you should be able to listen the ticks in the receiving computer. | ||
| + | |||
| + | <br /><br /> | ||
| + | ==Bidirectional Element== | ||
| + | ===Example=== | ||
| + | In this example we use two webrtcbin elements, each sends an audio stream and receives each other audio stream. | ||
| + | |||
| + | |||
| + | ====Send-Receive Pipeline==== | ||
| + | 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. | ||
| + | <syntaxhighlight lang='bash'> | ||
| + | gst-launch-1.0 webrtcbin start-call=true signaler=GstOwrSignaler 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 | ||
| + | </syntaxhighlight> | ||
| + | |||
| + | ====Send-Receive Pipeline==== | ||
| + | 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. | ||
| + | <syntaxhighlight lang='bash'> | ||
| + | gst-launch-1.0 webrtcbin start-call=false signaler=GstOwrSignaler 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 | ||
| + | </syntaxhighlight> | ||
| + | |||
| + | When executing the two previous pipelines, you should be able to listen the ticks and the white noise. | ||
