| CDAI Mechanism#2 – “Player Prebuffering” Feature |
Can be leveraged for quick stream transitions. Suitable for preroll, and midroll insertions. No limitations with respect to content type – can transition between DASH and HLS. detach()- Supported UVE version 0.9 and above.

Example use of detach and buffering: Code Block |
---|
| var player = new AAMPMediaPlayer();
player.load( “http://test.com/content.m3u8” ); // begin streaming main content
…
var adPlayer = new AAMPMediaPlayer(); // create background player
adPlayer.load( “http://test.com/ad.m3u8”, false ); // preroll
…
player.detach(); // stop playback of active player
adPlayer.play(); // activate background player (fast transition)
player.stop(); // release remaining resources for initial player instance |

| Inband Closed Caption Management |
To use inband closed captions, first register an event listener to discover decoder handle: Code Block |
---|
| player.addEventListener("decoderAvailable", decoderHandleAvailable); |
Along with corresponding event handler to publish the decoder handle to CC subsystem as follows: Code Block |
---|
| function decoderHandleAvailable(event) {
console.log("decoderHandleAvailable " + event.decoderHandle);
XREReceiver.onEvent("onDecoderAvailable", { decoderHandle: event.decoderHandle });
} |
Toggle CC display on or off at runtime: Code Block |
---|
| XREReceiver.onEvent("onClosedCaptions", { enable: true });
XREReceiver.onEvent("onClosedCaptions", { enable: false }); |
Set CC track at runtime: Code Block |
---|
| XREReceiver.onEvent("onClosedCaptions", { setTrack: trackID }); |
Set CC style options at runtime: Code Block |
---|
| XREReceiver.onEvent("onClosedCaptions", { setOptions: defaultCCOptions}); |
defaultCCOptions is a JSON object of various style options and its values. When closing stream, detach decoder handle: Code Block |
---|
| XREReceiver.onEvent("onDecoderAvailable", { decoderHandle: null }); |
Environments without the XREReceiver JS object may exist in future. Applications may use alternate CC rendering methods to avoid dependency on XREReceiver object. To use, turn on nativeCCRendering init configuration value to true as follows: Code Block |
---|
| player.initConfig( { nativeCCRendering: true } ); |
Toggle CC display on or off at runtime: Code Block |
---|
| player.setClosedCaptionStatus(true);
player.setClosedCaptionStatus(false); |
Get/Set CC track at runtime: Code Block |
---|
| player.getTextTrack();
player.setTextTrack(trackIndex); |
Get/Set CC style options at runtime: Code Block |
---|
| player.getTextStyleOptions();
player.setTextStyleOptions(options); |
options in a JSON formatted string of style options and its values.
