SourceBufferList interface represents a simple container list for multiple SourceBuffer 对象。

The source buffer list containing the SourceBuffer s appended to a particular MediaSource can be retrieved using the MediaSource.sourceBuffers property. The individual source buffers can be accessed using array operator (i.e. [] ) or functions such as forEach() 例如。

  <div id="interfaceDiagram" style="display: inline-block; position: relative; width: 100%; padding-bottom: 11.666666666666666%; vertical-align: middle; overflow: hidden;"><svg style="display: inline-block; position: absolute; top: 0; left: 0;" viewbox="-50 0 600 70" preserveAspectRatio="xMinYMin meet"><a xlink:href="../API/EventTarget.html" target="_top"><rect x="1" y="1" width="110" height="50" fill="#fff" stroke="#D4DDE4" stroke-width="2px" /><text  x="56" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">EventTarget</text></a><polyline points="111,25  121,20  121,30  111,25" stroke="#D4DDE4" fill="none"/><line x1="121" y1="25" x2="151" y2="25" stroke="#D4DDE4"/><a xlink:href="../API/SourceBufferList" target="_top"><rect x="151" y="1" width="160" height="50" fill="#F4F7F8" stroke="#D4DDE4" stroke-width="2px" /><text  x="231" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">SourceBufferList</text></a></svg></div>
