 The Media Source Extensions specification defines a set of classes which allows clients to implement their own loading, buffering, and variant switching behavior, as opposed to requiring the UA to handle same.

 MediaSource serves two purposes:

 * Creating SourceBuffer objects.
 * Associating those SourceBuffer objects with a HTMLMediaElement.
 
-Once created, clients can create query for container and codec support via `isTypeSupported(type)`, <doc:MediaSourceExtensions#SourceBuffer> objects via `addSourceBuffer(type)`, explicitly set the MediaSource's `duration`, and signal an end of the stream via `endOfStream(error)`.

 The MediaSource can be set directly as the HTMLMediaElement's `srcObject`. Alternatively, an [extension](https://github.com/WebKit/WebKit/blob/main/Source/WebCore/Modules/mediasource/DOMURL%2BMediaSource.idl) to DOMURL allows an ObjectURL to be created from a MediaSource object, and that ObjectURL can be set as the HTMLMediaElement's `src`.

 SourceBuffer accepts buffers of initialization segments and media segments, which are then parsed into media tracks and media samples. Those samples are cached within the SourceBuffer (inside its [SourceBufferPrivate](https://github.com/WebKit/WebKit/blob/main/Source/WebCore/platform/graphics/SourceBufferPrivate.h) object) 
-and enqueued into platform-specific decoders on demand. The primary storage mechanism for these samples is a <doc:MediaSourceExtensions#SampleMap>, which orders those samples both in terms of each sample's DecodeTime and PresentationTime. These two times can differ for codecs that support frame reordering, typically MPEG video codecs such as h.264 and HEVC.

 Clients append these segments via `appendBuffer()`, which sets an internal `updating` flag, fires the `"updatestart"` event, and subsequently fires the `"updateend"` event and clears the `updating` flag once parsing is complete. The results of the append are visible by querying the `buffered` property, or by querying the `audioTracks`, `videoTracks`, and `textTracks` TrackList objects.

 When the GPU Process is enabled, the MediaSourcePrivate in the WebContent process is typically a [MediaSourcePrivateRemote](https://github.com/WebKit/WebKit/blob/main/Source/WebKit/WebProcess/GPU/media/MediaSourcePrivateRemote.cpp), which will pass commands and properties across the WebContent/GPU process boundary.
 
 For Apple ports, the MediaSourcePrivate is typically a [MediaSourcePrivateAVFObjC](https://github.com/WebKit/WebKit/blob/main/Source/WebCore/platform/graphics/avfoundation/objc/MediaSourcePrivateAVFObjC.h).
 
 For GStreamer-based ports, the MediaSourcePrivate is typically a [MediaSourcePrivateGStreamer](https://github.com/WebKit/WebKit/blob/main/Source/WebCore/platform/graphics/gstreamer/mse/MediaSourcePrivateGStreamer.h).
