rmp-vast is a lightweight open-source client-side JavaScript solution to load, parse and display VAST resources. It is maintained by Radiant Media Player team and is offered as an alternative to the Google IMA SDK. The main purpose of rmp-vast is to offer a VAST 3 compliant solution to display video ads in web-based mobile applications for iOS and Android (WebView, Ionic, PhoneGap, Cordova ...) as the Google HTML5 IMA SDK is not officially compatible with those environments. rmp-vast can also be used in environments like desktop or mobile browsers.
rmp-vast supports the following VAST 3 features:
VAST 2 resources are also compatible with rmp-vast.
Additional supported features include a mobile friendly UI and autoplay support (muted autoplay on mobiles).
The following VAST/player features are currently not supported with rmp-vast: VMAP, Audio ads in HTML audio player, VAST4. Radiant Media Player supports those features through the Google IMA SDK.
Browsers:
Specifically we support the latest stable release for each browser.
WebViews:
It is fairly possible that rmp-vast would work in other environments but they are not officially supported.
When serving ads from Google Ads network (DFP, ADX, AdSense for Video) you must use the IMA HTML5 SDK with our player.
ADX & AdSense for Video ads will not render with our VAST parser rmp-vast. DFP ads may render with rmp-vast but we cannot guarentee full support. The choice of VAST parser
is made through the adParser player setting.
rmp-vast uses JavaScript XMLHttpRequests to load VAST tags. Hence proper CORS configuration is required on your ad-server in order for rmp-vast to be able to retrieve VAST tags. Refer to this Google documentation for more information.
Player settings for using rmp-vast are very similar to using Google IMA SDK. The only difference resides in specifying the VAST parser which you want to use through the
adParser setting.
Here is a complete example:
<!-- Include Radiant Media Player JavaScript file in your <body> or <head> --> <script src="https://cdn.radiantmediatechs.com/rmp/5.5.5/js/rmp-vast.min.js"></script> <!-- Player container element --> <div id="rmpPlayer"></div> <script> // Streaming source - HLS in this example var src = { hls: 'https://your-hls-url.m3u8' }; // Player settings var settings = { licenseKey: 'your-license-key', src: src, width: 640, height: 360, ads: true, // We tell the player to use rmp-vast to load and parse VAST resources adParser: 'rmp-vast', // We pass our adTag here - the player will attempt to load it upon startup adTagUrl: 'https://your-ad-tag-url', poster: 'https://your-poster-url.jpg' }; var elementID = 'rmpPlayer'; var rmp = new RadiantMP(elementID); rmp.init(settings); </script>
<!-- Player container element --> <div id="rmpPlayer"></div> <!-- Set up async player configuration options --> <script> // Streaming source - HLS in this example var src = { hls: 'https://your-hls-url.m3u8' }; // Player settings var settings = { licenseKey: 'your-license-key', src: src, width: 640, height: 360, ads: true, // We tell the player to use rmp-vast to load and parse VAST resources adParser: 'rmp-vast', // We pass our adTag here - the player will attempt to load it upon startup adTagUrl: 'https://your-ad-tag-url', poster: 'https://your-poster-url.jpg', // Here we pass the ID of the player container so that the core library may automatically initialize player when it finishes loading asyncElementID: 'rmpPlayer' }; // We push the player settings to a global rmpAsyncPlayers variable if (typeof window.rmpAsyncPlayers === 'undefined') { window.rmpAsyncPlayers = []; } window.rmpAsyncPlayers.push(settings); </script> <script async src="https://cdn.radiantmediatechs.com/rmp/5.5.5/js/rmp-vast.min.js"></script>
ads: Boolean
Activate or not ads within the player. Default: false.
adTagUrl: String
Specifies the ad tag url that is requested by the player from the ad server. Default: ''.
We recommend using fully qualified URLs for the
adTagUrl setting
adParser: String
Specifies which VAST parser the player should use. Possible values are 'rmp-vast' and 'ima'. Default: 'ima'.
adLoadVastTimeout: Number
Represents the Ajax timeout in milliseconds for each VAST request (or VAST wrapper). When timeout is reached without a valid server response the VAST loading process is aborted. Default: 5000.
adLoadMediaTimeout: Number
Timeout (in milliseconds) when loading a creative media file (after a successful VAST response). If loading takes longer than this timeout, the ad playback is cancelled and content resumes. Default: 8000 which represents a 8 seconds timeout.
adAjaxWithCredentials: Boolean
AJAX request to load VAST tag from ad server should or should not be made with credentials. Default: false.
adMaxNumRedirects: Number
Specifies the maximum number of redirects before the subsequent redirects will be denied, and the ad load aborted. The number of redirects directly affects latency and thus user experience. This applies to all VAST wrapper ads. Default: 4.
adShowMarkers: String
Adds markers on timeline for on-demand streams indicating to viewers when ad-breaks are scheduled. Works for VMAP tags and our ad-scheduler. Default: true.
adPauseOnClick: Boolean
When set to true this setting will cause to pause the playing linear ad (or content for a non-linear ad) when the ad is interacted with. Default: true. On some devices the browser may still decide to pause a video asset when a new window opens.
adCountDown: Boolean
A countdown to be displayed within the player control bar. It shows the remaining time for the video ads. Default: false.
adTagReloadOnEnded: Boolean
When set to true this setting will cause the player to attempt to reload the initial adTag (or VMAP/ad-schedule) when a user requests content to be played after having ended. This setting is compatible with the adTagWaterfall setting
and outstream ads. Default: true.
See our documentation about player labels here.
var labels = {
ads: {
controlBarCustomMessage: 'Ad',
skipMessage: 'Skip ad',
skipWaitingMessage: 'Skip ad in',
textForClickUIOnMobile: 'Learn more'
}
};
labels.ads.skipMessage: the skip message to show on player when a skippable ad is detected and the ad is in a state where it can be skipped. Default: 'Skip ad'
labels.ads.skipWaitingMessage: the skip message to show on player when a skippable ad is detected and the ad is in a state where it cannot be skipped. Default: 'Skip ad in'. This will be completed by the number of seconds remaining
before the ad state changes to a state where it can be skipped.
labels.ads.textForClickUIOnMobile: on mobile devices the click-through URL for a linear ad is provided in a box located at the top right corner of the player. This setting set the text for this box. Default: 'Learn more'.
As when using the Google IMA SDK, autoplay of pre-roll linear video ads on desktop and muted autoplay on mobile devices are supported. Refer to our documentation about autoplay support for more information.
Since Radiant Media Player 4.5.1 we support ad scheduling with rmp-vast through our ad scheduler.
VAST redirect / VAST Wrapper have always been supported with rmp-vast since it was made publicly available. Since Radiant Media Player 4.5.2 we also support ad waterfalling through the
adTagWaterfall setting with rmp-vast. See our
ad waterfalling documentation for more information.
See the companion ads documentation for more information on how to retrieve companion ads information with rmp-vast.
