Player example

This player can be used to play any type of stream on Web Call Server

  • RTSP
  • WebRTC
  • RTMP
  • RTMFP
  • SIP

On the screenshot below an RTSP stream is being playing in the web player.


Code of the example

The path to the source code of the example on WCS server is:

/usr/local/FlashphonerWebCallServer/client2/examples/demo/streaming/player

player.css - file with styles
player.html - page of the player
player.js - script providing functionality for the player

This example can be tested using the following address:

https://host:8888/client2/examples/demo/streaming/player/player.html

Here host is the address of the WCS server.

Work with code of the player

To analyze the code, let's take the version of file player.js with hash 66cc393, which is available here and can be downloaded with corresponding build 0.5.28.2753.133.

1. Initialization of the API.

Flashphoner.init() code

        Flashphoner.init({
            flashMediaProviderSwfLocation: '../../../../media-provider.swf',
            receiverLocation: '../../dependencies/websocket-player/WSReceiver2.js',
            decoderLocation: '../../dependencies/websocket-player/video-worker2.js',
            preferredMediaProvider: mediaProvider
        });

2. Connection to server

Flashphoner.createSession() code

    Flashphoner.createSession({urlServer: url}).on(SESSION_STATUS.ESTABLISHED, function(session){
        setStatus(session.status());
        //session connected, start playback
        playStream(session);
    }).on(SESSION_STATUS.DISCONNECTED, function(){
        setStatus(SESSION_STATUS.DISCONNECTED);
        onStopped();
    }).on(SESSION_STATUS.FAILED, function(){
        setStatus(SESSION_STATUS.FAILED);
        onStopped();
    });

3. Receiving the event confirming successful connection

ConnectionStatusEvent ESTABLISHED code

    Flashphoner.createSession({urlServer: url}).on(SESSION_STATUS.ESTABLISHED, function(session){
        setStatus(session.status());
        //session connected, start playback
        playStream(session);
    }).on(SESSION_STATUS.DISCONNECTED, function(){
        ...
    }).on(SESSION_STATUS.FAILED, function(){
        ...
    });

4. Playback of video stream.

session.createStream(), play() code

When stream is created, the following parameters are passed

  • streamName - name of the stream (rtsp:// address in this case)
  • remoteVideo - <div> element, in which the video will be displayed
    stream = session.createStream(options).on(STREAM_STATUS.PENDING, function (stream) {
        ...
    });
    stream.play();

When stream is created, the following parameters are passed

  • streamName - name of the stream (rtsp:// address in this case)
  • remoteVideo - <div> element, in which the video will be displayed
  • picture reslution to transcode
    var options = {
        name: streamName,
        display: remoteVideo,
        flashShowFullScreenButton: true
    };
    if (Flashphoner.getMediaProviders()[0] === "MSE" && mseCutByIFrameOnly) {
        options.mediaConnectionConstraints = {
            cutByIFrameOnly: mseCutByIFrameOnly
        }
    }
    if (resolution_for_wsplayer) {
        options.playWidth = resolution_for_wsplayer.playWidth;
        options.playHeight = resolution_for_wsplayer.playHeight;
    } else if (resolution) {
        options.playWidth = resolution.split("x")[0];
        options.playHeight = resolution.split("x")[1];
    }

5. Receiving the event confirming successful stream playback

StreamStatusEvent PLAYING code

    stream = session.createStream(options).on(STREAM_STATUS.PENDING, function (stream) {
        ...
    }).on(STREAM_STATUS.PLAYING, function (stream) {
        $("#preloader").hide();
        setStatus(stream.status());
        onStarted(stream);
    }).on(STREAM_STATUS.STOPPED, function() {
        ...
    }).on(STREAM_STATUS.FAILED, function() {
        ...
    });
    stream.play();

6. Stop of playback.

stream.stop() code

function onStarted(stream) {
    $("#playBtn").text("Stop").off('click').click(function(){
        $(this).prop('disabled', true);
        stream.stop();
    }).prop('disabled', false);
    ...
}

7. Receiving the event confirming successful stream playback stop

StreamStatusEvent STOPPED code

    stream = session.createStream(options).on(STREAM_STATUS.PENDING, function (stream) {
        ...
    }).on(STREAM_STATUS.STOPPED, function () {
        $("#preloader").hide();
        setStatus(STREAM_STATUS.STOPPED);
        onStopped();
    }).on(STREAM_STATUS.FAILED, function() {
        ...
    }).play();

8. Playback volume control

stream.unmuteRemoteAudio(), stream.setVolume(currentVolumeValue) code

    $("#volumeControl").slider({
        range: "min",
        min: 0,
        max: 100,
        value: currentVolumeValue,
        step: 10,
        animate: true,
        slide: function(event, ui) {
            //WCS-2375. fixed autoplay in ios safari
            stream.unmuteRemoteAudio();
            currentVolumeValue = ui.value;
            stream.setVolume(currentVolumeValue);
        }
    }).slider("disable");
