To migrate an application from Tizen to TOAST, you must create a TOAST application using the Tizen application as a template, and make the necessary changes in the code.
Some Tizen APIs do not have a TOAST equivalent. To detect when the application is run on a Samsung TV and can use Tizen-specific APIs, see How to detect platform.
Creating a TOAST Application
To migrate a Tizen application to TOAST:
Remove the existing "config.xml" file from the application.
ImportantThe Tizen "config.xml" file is not compatible with TOAST.
NoteThe "cordova.js" library must be included before the "toast.js" library.
Before using the TOAST APIs, you must wait until Cordova is fully set up (the deviceready event occurs):
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log("start the app");
}
Migrate functionality from Tizen API modules.
The following section presents examples of how to migrate media playback functionalities to TOAST. For information on how to migrate functionality from other Tizen API modules, see the TOAST Wiki.
NoteTOAST automatically manages the screensaver. It does not need to be explicitly managed, such as with the setScreenSaver() method of the AVPlay API.
To open media for playback:
Before:
webapis.avplay.open('url');
After:
var media = toast.Media.getInstance();
media.open('url');
To start media playback:
Before:
webapis.avplay.prepare();
webapis.avplay.setDisplayRect(x, y, width, height);
webapis.avplay.play();
var status = webapis.appcommon.AppCommonScreenSaverState.SCREEN_SAVER_OFF;
webapis.appcommon.setScreenSaver(status, function() {}, function() {});
webapis.avplay.stop();
var status = webapis.appcommon.AppCommonScreenSaverState.SCREEN_SAVER_ON;
webapis.appcommon.setScreenSaver(status, function() {}, function() {});
After:
media.stop();
To pause media playback:
Before:
webapis.avplay.pause();
var status = webapis.appcommon.AppCommonScreenSaverState.SCREEN_SAVER_ON;
webapis.appcommon.setScreenSaver(status, function() {}, function() {});
After:
media.pause();
To jump forward during media playback:
Before:
webapis.avplay.jumpForward(10000); // Number of milliseconds to move forward
After:
var curPos = media.getCurrentPosition();
media.seekTo(curPos + 10000); // Position to seek to in milliseconds
To jump backward during media playback:
Before:
webapis.avplay.jumpBackward(10000); // Number of milliseconds to move backward
After:
var curPos = media.getCurrentPosition();
media.seekTo(curPos - 10000); // Position to seek to in milliseconds
media.setListener({
onevent: function(evt) {
switch (evt.type) {
case 'STATE':
console.log('Media State changed: ' + evt.data.oldState + ' -> ' + evt.data.state);
break;
case 'DURATION':
console.log('Media duration updated: ' + evt.data.duration + 'ms');
break;
case 'POSITION':
console.log('Media position updated: ' + evt.data.position + 'ms');
break;
case 'BUFFERINGPROGRESS':
console.log('Media buffering in progress: ' + evt.data.bufferingPercentage + '%');
if (evt.data.bufferingPercentage >= 100) {
console.log('Buffering completed');
}
break;
case 'ENDED':
console.log('Media ended');
break;
}
},
onerror: function (err) {
console.error('MediaError occured: ' + JSON.stringify(err));
}
});
To play streaming, 4K, and DRM-enabled content, the toast.MediaPlugin constructor binds to the toast.Media constructor with specific configuration data. For example:
var media= toast.Media.getInstance();
var mediaPlugin = new toast.MediaPluginHLS();
media.resetPlugin();
media.attachPlugin(mediaPlugin);
media.open('http://mydomain.com/video.m3u8');
webapis.avplay.open('url');
var widevineData = 'DEVICE_ID=myDeviceId|DEVICET_TYPE_ID=myDeviceTypeId|STREAM_ID=myStreamId|DRM_URL=http://yourDrmUrl.com|I_SEEK=yourI\_SEEK|CUR_TIME=yourCurTime|PORTAL=yourPortal|USER_DATA=yourUserData'
webapis.avplay.setStreamingProperty('WIDEVINE', wideVineData);
webapis.avplay.prepare();
After:
var wideVineData = {
DEVICE_ID : 'yourDeviceId',
DEVICET_TYPE_ID : 'yourDeviceTypeId', for example, '60'
STREAM_ID : 'yourStreamId',
DRM_URL : 'http://yourDrmUrl.com',
I_SEEK : 'yourI\_SEEK', for example, 'TIME'
CUR_TIME : 'yourCurTime', for example, 'PTS'
PORTAL : 'yourPortal',
USER_DATA : 'yourUserData',
};
var mediaPlugin = new toast.MediaPluginWideVine(wideVineData);
media.attachPlugin(mediaPlugin);
// Widevine data must be set before calling the "open()" method
media.open('url');
var playReadyData = {
LicenseServer : 'myLicenseServer',
CustomData : 'myCustomData'
};
var mediaPlugin = new toast.MediaPluginPlayReady(playReadyData);
