Tutorial: Work with TimeShift subsystem

TimeShift preparations:

// set folder for saving TimeShift buffer data
timeShift.SetTimeShiftFolder(pathToSave);
// set buffer duration in seconds
timeShift.SetMaxDuration(durationSec);
// set mode which defines what happens after reaching the left boundary of TimeShift buffer in paused mode
timeShift.SetSlidingMode(true);

Event model initialization:

window.stbEvent = {
    onEvent: function ( event, info ) {
        if ( Number(event) === 36 ) {
            info = JSON.parse(info);
            console.log('TimeShift mode is enabled. TimeShift data:', info);
        }
    }
};

Work with TimeShift event:

switch ( info.event_code ) {
    case 1:
        console.log('TimeShift system ready to start and writing buffer after start playing with solution extTimeShift.');
        break;
    case 2:
        console.log('TimeShift was closed.');
        break;
    case 3:
        console.log('Buffer continues writing to right boundary and drop all data from left boundary.');
        break;
    case 4:
        console.log('Buffer is full. Buffer writing was stopped.');
        break;
    case 5:
        console.log('Buffer will be full after 1 minute.');
        break;
    case 6:
        switch ( parseInt(info.event_data, 10) ) {
            case 1:
                console.log('Folder error. May be folder was unmounted or full.');
                break;
            case 2:
                console.log('Some else error');
                break;
        }
        break;
    case 7:
        console.log('End playing of TimeShift buffer.');
        break;
}

Start playback of an internet stream with one of the following methods:

// legacy
gSTB.Play('extTimeShift ' + uri);

// new recommended approach
stbPlayerManager.list[0].play({uri: uri, solution: 'extTimeShift'});

Enter TimeShift mode:

timeShift.EnterTimeShift();

Different methods to exit from TimeShift mode:

// return to real-time mode without saving:
timeShift.ExitTimeShift();

// return to real-time mode and save current TimeShift buffer via PVR:
timeShift.ExitTimeShiftAndSave(pathToSave2, fileName1);

// return to real-time mode and save TimeShift buffer via PVR with possibility to continue recording:
timeShift.ExitTimeShiftAndSaveDuration(pathToSave3, fileName2, durationSec2);
