WebRTC stream playback in custom player
SA stream published on WCS server can be played via WebRTC in custom player, for example, in a VR player. To fo this, video page element to play stream should be passed as remoteVideo
parameter to session.createStream() WebSDK function
session.ceateStream() code
Code Block | ||||
---|---|---|---|---|
| ||||
session.createStream({
name: document.getElementById('playStream').value,
display: display,
remoteVideo: video
})

Testing
1. For test we use:
- WCS server
- Two Way Streaming web application to publish a stream
- Delight VR player to play a stream
2. Publish stream on WCS server
3. Play stream in VR player
Custom player page code sample
1. Video page element, stream name input field and buttons to start and stop playback declaration
Code Block | ||||
---|---|---|---|---|
| ||||
<div style="width: 50%;" id="display">
<dl8-live-video id="remoteVideo" format="STEREO_TERPON">
<source>
</dl8-live-video>
</div>
<input class="form-control" type="text" id="playStream" placeholder="Stream Name">
<button id="playBtn" type="button" class="btn btn-default" disabled>Play</button>
<button id="stopBtn" type="button" class="btn btn-default" disabled>Stop</button> |
2. Player ready to playback event handling
Code Block | ||||
---|---|---|---|---|
| ||||
document.addEventListener('x-dl8-evt-ready', function () {
dl8video = document.getElementById('remoteVideo');
$('#playBtn').prop('disabled', false).click(function() {
playStream();
});
}); |
3. Connection to WCS server establishing and stream creation
Code Block | ||||
---|---|---|---|---|
| ||||
var video = dl8video.contentElement;
Flashphoner.createSession({urlServer: url}).on(SESSION_STATUS.ESTABLISHED, function (session) {
var session = Flashphoner.getSessions()[0];
session.createStream({
name: document.getElementById('playStream').value,
display: display,
remoteVideo: video
}).on(STREAM_STATUS.PLAYING, function (stream) {
...
}).play();
}) |
4. Start playback in VR player and stop button click handling
Code Block | ||||
---|---|---|---|---|
| ||||
...
}).on(STREAM_STATUS.PLAYING, function (stream) {
dl8video.start();
$('#stopBtn').prop('disabled', false).click(function() {
$('#playBtn').prop('disabled', false);
$('#stopBtn').prop('disabled', true);
stream.stop();
dl8video.exit();
});
}).play();
}) |
