This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

The SourceBufferList interface represents a simple container list for multiple SourceBuffer objects.

The source buffer list containing the SourceBuffers 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() for example.
