The individual source buffers can be accessed using the array operator [].

Examples

This example shows how to access the active source buffers of the MediaSource connected to an already playing HTMLVideoElement.

// Video is an already playing video using a MediaSource srcObject
var video = document.querySelector('video');
var mediaSource = video.srcObject;
var sourceBufferList = mediaSource.activeSourceBuffers;
for (var i = 0; i < sourceBufferList.length; i++) {
  var sourceBuffer = sourceBufferList[i];
  // Do something with each SourceBuffer, such as call abort()
  sourceBuffer.abort();
}
