Check 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.

1. Limited support to a whitelist of sites, for example YouTube, Netflix, and other popular streaming sites. The whitelist was removed when Media Source Extensions was enabled by default in Firefox 42.
2. From version 25 until version 42 (exclusive): this feature is behind the media.mediasource.enabled preference. To change preferences in Firefox, visit about:config.
3. Only works on Windows 8+.
