Radiant Media Player playlist layout allows for a collection of video items to be displayed with an intuitive, mobile-ready UI. Playlist items are displayed on a scroll-able side panel and in-player arrows allow navigation between playlist items. We also support audio playlist.
Video ads can be played each time a new playlist item is loaded within the player. The playlist UI is fully compatible with mobile devices. A built-in error-recovery mechanism is also provided to skip playlist items that may be unavailable.
The playlist layout is compatible with most player features including HLS & DASH streaming, analytics and a dedicated playlist API exists to programmatically control the playlist layout. Our playlist layout is compatible with Google Cast and AirPlay.
The playlist player can be initialised by passing through the playlistLoc setting a URI to a JSON file holding playlist data. Here is a full
example of well-formatted JSON file that can be used with Radiant Media Player playlist layout.
The general structure is as below. The required fields for each item are:
src - streaming source for the playlist itemcontentMetadata:
{
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"duration": "09:56",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
}
poster: poster frame for the playlist item - size should be equal to the initial player size (832x468 per default)title: title for the playlist itemdescription: description for the playlist itemthumbnail (highly recommended) - URI to thumbnail frame for the playlist item (size should be 80x45) - if thumbnail information is not found poster data will be used
Optional fields for each playlist item are:
adTagUrl - URI to the adTag to be loaded when the playlist item starts - if you use ads you must also set the player setting ads to trueadTagWaterfall - an array of URI to be used for client-side waterfalling -
see here for more information
seekBarThumbnailsLoc - VTT file URI to be loaded with each playlist item to enable preview thumbnail supportccFiles - WebVTT closed captions files -
see documentation
chaptersLoc - WebVTT chapters files -
see documentation
sharingUrl and sharingCode (provided sharing: true setting is set - this will let you define individual sharing URL and code for each playlist item) - see sharing documentation
logo and logoLoc - see logo
documentation All items within the playlist must have the same src type (e.g. if you use HLS - each playlist item must have a HLS URI in its src information; if you use MP4 progressive
download - each playlist item must have a MP4 URI in its
src information)
Example:
{
"playlist": [
{
"src": {
"hls": "https://your-hls-url-1.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
},
"adTagUrl": "https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml"
},
{
"src": {
"hls": "https://your-hls-url-2.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 2",
"description": "Description for playlist item 2",
"id": "2222222222",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-2-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-2.jpg"
]
},
"adTagUrl": "https://www.radiantmediaplayer.com/vast/tags/inline-linear-skippable.xml"
},
{
"src": {
"hls": "https://your-hls-url-3.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 3",
"description": "Description for playlist item 3",
"id": "3333333333",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-3-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-3.jpg"
]
},
"adTagUrl": "https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/single_ad_samples&ciu_szs=300x250&impl=s&gdfp_req=1&env=vp&output=vast&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ct%3Dlinear&correlator="
}
]
}
If you are using MP4 progressive download instead of HLS each item in the playlist would look like the following. Remember that all items in the playlist must have the same streaming protocol.
{
"src": {
"mp4": [
"https://your-mp4-url-1.mp4"
]
},
"contentMetadata": {
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
},
"adTagUrl": "https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml"
}
You can also use a combination of streaming protocols, like DASH + MP4 fallback. In this case all items in the playlist must have the same combination of streaming protocols.
{
"src": {
"dash": "https://your-dash-url-1.mpd",
"mp4": [
"https://your-mp4-url-1.mp4"
]
},
"contentMetadata": {
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
},
"adTagUrl": "https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml"
}
Client-side ad waterfalling with playlist items:
{
"src": {
"hls": "https://your-hls-url-1.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
},
"adTagUrl": "https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml",
"adTagWaterfall": [
"https://www.radiantmediaplayer.com/vast/tags/inline-linear-1.xml?cb=__random-number__",
"https://www.radiantmediaplayer.com/vast/tags/inline-linear-2.xml?url=__page-url__"
]
}
WebVTT closed captions through the ccFiles setting:
{
"src": {
"hls": "https://your-hls-url-1.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
},
"ccFiles": [
[
"en",

]
]
}
Alternatively to passing playlist data as a JSON file you can pass those data through the
playlistData setting as an array of objects. Each item of the array is an object representing a playlist item. The structure of this object follows the same pattern as the one described in the JSON file section above. Example:
const playlistData = [{
src: {
hls: "https://your-hls-url-1.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 1",
"description": "Description for playlist item 1",
"id": "1111111111",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
},
adTagUrl: "https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml"
}, {
src: {
hls: "https://your-hls-url-2.m3u8"
},
"contentMetadata": {
"title": "Playlist Item 2",
"description": "Description for playlist item 2",
"id": "2222222222",
"thumbnail": "https://www.radiantmediaplayer.com/media/playlist/poster/item-2-thumbnail.jpg",
"poster": [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-2.jpg"
]
},
adTagUrl: "https://www.radiantmediaplayer.com/vast/tags/inline-linear-skippable.xml"
}];
...
const settings = {
licenseKey: 'your-license-key',
playlistUpNextAutoplay: true,
playlistEndedLoop: false,
playlistData: playlistData
};
playlistLoc: String
This set the location to the JSON file that hold information about the playlist. It can either be a fully qualified URL or a local/absolute path. Note that the playlist JSON file is loaded with XMLHttpRequest and thus it must be delivered with
proper CORS setting for cross-site requests. Default: ''.
playlistData: Array
This setting sets the initial playlist data based on an JavaScript array of objects. Default: []. If both playlistLoc and playlistData are set
playlistData will prevail. See above for an example. Default: [].
playlistCallback: Function
This setting allows for a custom callback (Promise) to be run during the playlist mechanism after a new playlist item has been requested (including the first item) but before it actually starts loading playlist data for that item. The playlist
item loading process will only resume when the Promise from the custom callback resolves or rejects. This allows for use-cases that require the playlist item loading process to pause, like header bidding for video ads, to be handled in a playlist
scenario. Default:
null. Usage example:
const adTags = [
'https://www.radiantmediaplayer.com/vast/tags/inline-linear-1.xml',
'https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml',
'https://www.radiantmediaplayer.com/vast/tags/inline-linear-skippable.xml',
'https://www.radiantmediaplayer.com/vast/tags/non-linear.xml'
];
let adIndex = 0;
const playlistCallback = () => {
return new Promise((resolve, reject) => {
// run something async
setTimeout(() => {
if (adIndex === 4) {
adIndex = 0;
}
rmp.loadAds(adTags[adIndex]);
adIndex++;
resolve();
}, 1000);
});
};
const settings = {
licenseKey: 'your-license-key',
width: 640,
height: 360,
ads: true,
// pass async playlist callback
playlistCallback: playlistCallback,
playlistLoc: 'https://www.radiantmediaplayer.com/media/playlist/playlist-no-ad.json'
};
const rmp = new RadiantMP('rmp');
rmp.init(settings);
playlistUpNextAutoplay: Boolean
By default when a playlist item ends the next playlist item is automatically played. Default: true. Setting this setting to false will cause the player to not autoplay the next item.
playlistEndedLoop: Boolean
By default when the last item of the playlist ends the player stops and remains on the last item. When playlistEndedLoop is set to true and the last item of the playlist ends the player will automatically start loading and displaying
the first item in the playlist (e.g. playlist loop). Default: false. When
playlistEndedLoop is set to true playlistUpNextAutoplay must also be set to true to have effect.
The below code is used to display the playlist example at top of this page:
Take note of the additional div elements required to display the playlist UI.
<script src="https://cdn.radiantmediatechs.com/rmp/9.10.0/js/rmp.min.js"></script> <!-- Here is our specific markup for playlist --> <div class="rmp-playlist-container"> <div class="rmp-playlist-player-wrapper"> <div id="rmp"></div> </div> </div> <script> const settings = { licenseKey: 'your-license-key', // if you want ads to show uncomment this next setting (ad data for each playlist item can be passed in JSON file) // ads: true, // our playlist settings playlistUpNextAutoplay: true, playlistEndedLoop: false, playlistLoc: 'https://www.radiantmediaplayer.com/media/playlist/playlist.json' }; const rmp = new RadiantMP('rmp'); rmp.init(settings); </script>
playlistitem

isPlaylist()
rmp.isPlaylist();
This method returns a boolean stating if the player is used with a playlist layout.
getCurrentPlaylistItemIndex()
rmp.getCurrentPlaylistItemIndex();
This getter returns a Number representing the index of the current playlist item being displayed. Index starts at 0.
getPlaylistItem(index)
rmp.getPlaylistItem(index);
This getter returns an Object representing the playlist item at index index. If no index value input is provided, then the current playlist item is returned. Example:
{
adTagUrl: "https://www.radiantmediaplayer.com/vast/tags/inline-linear.xml",
src: {
hls : "https://your-hls-url.m3u8"
},
contentMetadata: {
title: "Playlist Item 1",
description: "Description for playlist item 1",
"id": "1111111111",
thumbnail: "https://www.radiantmediaplayer.com/media/playlist/poster/item-1-thumbnail.jpg",
poster: [
"https://www.radiantmediaplayer.com/media/playlist/poster/item-1.jpg"
]
}
}
setPlaylistItem(index) asynchronous
rmp.setPlaylistItem(1);
This method sets the current playlist item being displayed.
index input parameter should be a number representing the desired playlist item to be displayed. srcchanged or
error event will fire when this method has completed (see setSrc
API docs for more information).
getPlaylistData()
rmp.getPlaylistData();
This method returns an ordered Array of Object where each Object represents a playlist item.
setPlaylistData(playlistLoc|playlistData) asynchronous
rmp.setPlaylistData('https://www.radiantmediaplayer.com/media/playlist/playlist.json');
rmp.setPlaylistData(playlistData);
This method allows to dynamically update the playlist player with a new set of data. You can either pass a URI to new JSON file (see playlistLoc setting) or a new array of object (see
playlistData setting). srcchanged or
error event will fire when this method has completed (see setSrc
API docs for more information).
setPlaylistItemCallback(Function)
rmp.setPlaylistItemCallback(customCallback);
This method sets dynamically the playlistCallback setting. This setting allows for a custom callback (Promise) to be run during the playlist mechanism after a new playlist item has been requested (including the first item) but before
it actually starts loading playlist data for that item. The playlist item loading process will only resume when the Promise from the custom callback resolves or rejects. This allows for use-cases that requires the playlist item loading process
to pause, like header bidding for video ads, to be handled in a playlist scenario.
resetPlaylistItemCallback()
rmp.resetPlaylistItemCallback();
This method resets the playlistCallback setting to
null therefore allowing the playlist loading process to run without interruption.
The playlist UI uses media queries to adjust itself based on viewport dimensions. It is meant to be a central element within a web page. Review the playlist.less Less CSS file from within the self-hosted package for further sizing information and customisation.
You can use 360 video content with our playlist layout but all items within the playlist have to be 360 video
Each time a new item starts in the playlist layout, a player start is counted (PLATFORM Edition).
Each time a new item starts in the playlist layout, a playerstart event is sent to Google Analytics, but it will use as label the contentTitle of the new item. This allows to identify when a specific playlist item is started. Other events, like adimpression or enterfullscreen, will also be sent to Google Analytics when a new media item starts in the playlist layout, but with the updated label as well.
