Dash.js: Setting Mute and Changing Volume in a Media Player
Dash.js is an open-source JavaScript library developed by the DASH Industry Forum for handling MPEG-DASH (Dynamic Adaptive Streaming over HTTP) adaptive bitrate streaming. This article will focus on how to set the mute property and change the volume of a media player using the dash.js library.
Initializing the Dash.js Player
To start using dash.js, you first need to initialize the MediaPlayer object, specifying the video element and the MPD URL. The MPD (Media Presentation Description) file contains the information about the available streams and their characteristics.
this.dsh = dashjs.MediaPlayer();
this.dsh.initialize(this.v, <your\_mpd\_url>, true);
Setting Mute Property
To mute the media player, you can set the muted property of the video element to true. However, if the playback is not allowed, the PLAYBACK_NOT_ALLOWED event will be triggered. In such cases, you can re-initialize the dash.js player with the muted property set to true.
this.dsh.on(dashjs.MediaPlayer.events.PLAYBACK\_NOT\_ALLOWED, () => {
this.dsh.initialize(this.v, <your\_mpd\_url>, this.v.muted = true);
});
Changing the Volume
To change the volume of the media player, you can use the volume property of the video element. The volume property accepts a value between 0.0 (silent) and 1.0 (maximum volume).
// Set the volume to 50%
this.v.volume = 0.5;
