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
    publishStream(session);
}).on(SESSION_STATUS.DISCONNECTED, function(){
    ...
}).on(SESSION_STATUS.FAILED, function(){
    ...
});

4. Video streaming.

session.createStream(), and function publish() is called to publish the stream. code
When stream is created, the following parameters are passed

• streamName - name of the stream
• localVideo - <div> element, in which video from camera will be displayed
• true for parameter 'record' - to enable stream recording

session.createStream({
    name: streamName,
    display: localVideo,
    record: true
    ...
}).publish();

5. Receiving the event confirming successful streaming

StreamStatusEvent PUBLISHING code

session.createStream({
    name: streamName,
    display: localVideo,
    record: true
}).on(STREAM_STATUS.PUBLISHING, function(stream) {
    setStatus(stream.status());
    onStarted(stream);
}).on(STREAM_STATUS.UNPUBLISHED, function(stream) {
    ...
}).on(STREAM_STATUS.FAILED, function(stream) {
     setStatus(stream.status());
    showDownloadLink(stream.getRecordInfo());
    onStopped();...
}).publish();

6. Streaming stop

stream.stop() code

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

7. Receiving the event confirming successful streaming stop

StreamStatusEvent UNPUBLISHED code

On receiving the event, showDownloadLink() function is called to form the record file download link. The record file name returned by stream.getRecordInfo() method passed to the showDownloadLink() function.

session.createStream({
    name: streamName,
    display: localVideo,
    record: true
}).on(STREAM_STATUS.PUBLISHING, function(stream) {
    ...
}).on(STREAM_STATUS.FAILEDUNPUBLISHED, function(stream) {
    setStatus(stream.status());
    showDownloadLink(stream.getRecordInfo());
    onStopped();
}).publish();

...

on(STREAM_STATUS.FAILED

...

STREAM_STATUS.PUBLISHING - when this status is received, function onStarted() of the example is called to make appropriate changes in controls of the interface.

STREAM_STATUS.UNPUBLISHED and STREAM_STATUS.FAILED - when one of these statuses is received

• function showDownloadLink() of the example is called to form the download link
• function onStopped() of the example is called to make appropriate changes in controls of the interface

When showDownloadLink() is called, the name of the file with the recording is passed to it. To get the file name, method stream.getRecordInfo() is used.

...

, function(stream) {
    ...
}).publish();

8. Download link.

код

function showDownloadLink(name) {
    if (name) {
        // Set correct path for records. Stream records are saved to WCS_HOME/records directory.
        // http://flashphoner.com/docs/wcs4/wcs_docs/html/en/wcs-developer-guide/quick_start_recording_streams.htm
        var link = window.location.protocol + "//" + window.location.host + '/client/records/' + name;
        $("#link").attr("href", link);
        $("#recVideo").attr("src", link).attr("controls", true);
        $("#downloadDiv").show();
    }
}

Stream recordings are saved to directory WCS_HOME/client/records.

When the link is formed,:

• window.location.protocol is the protocol being used (HTTP or HTTPS)
• window.location.host is <address of the WCS server>:<port>
• name is name of the file with the recording

5. Stop of streaming. line 24
