IMFMediaSourceExtension interface (mfmediaengine.h)
Provides functionality for the Media Source Extension (MSE).
Inheritance
The IMFMediaSourceExtension interface inherits from the IUnknown interface. IMFMediaSourceExtension also has these types of members:
Methods
The IMFMediaSourceExtension interface has these methods.
| IMFMediaSourceExtension::AddSourceBuffer Adds a IMFSourceBuffer to the collection of buffers associated with the IMFMediaSourceExtension. |
| IMFMediaSourceExtension::GetActiveSourceBuffers Gets the source buffers that are actively supplying media data to the media source. |
| IMFMediaSourceExtension::GetDuration Gets the duration of the media source in 100-nanosecond units. |
| IMFMediaSourceExtension::GetReadyState Gets the ready state of the media source. |
| IMFMediaSourceExtension::GetSourceBuffer Gets the IMFSourceBuffer at the specified index in the collection of buffers. |
| IMFMediaSourceExtension::GetSourceBuffers Gets the collection of source buffers associated with this media source. |
| IMFMediaSourceExtension::IsTypeSupported Gets a value that indicates if the specified MIME type is supported by the media source. |
| IMFMediaSourceExtension::RemoveSourceBuffer Removes the specified source buffer from the collection of source buffers managed by the IMFMediaSourceExtension object. |
| IMFMediaSourceExtension::SetDuration Sets the duration of the media source in 100-nanosecond units. |
| IMFMediaSourceExtension::SetEndOfStream Indicate that the end of the media stream has been reached. |
Remarks
Media Source Extensions (MSE) is a World Wide Web Consortium (W3C) standard that extends the HTML5 media elements to enable dynamically changing the media stream without the use of plug-ins. The IMFMediaSourceExtension interface and the related Microsoft Win32 API implement MSE and are expected to only be called by web browsers implementing MSE.
The MSE media source keeps track of the ready state of the of the source as well as a list of IMFSourceBuffer objects which provide media data for the source.
