Gets and sets media types on an object, such as a media source or media sink.

Inheritance

The IMFMediaTypeHandler interface inherits from the IUnknown interface. IMFMediaTypeHandler also has these types of members:

Methods

The IMFMediaTypeHandler interface has these methods.


IMFMediaTypeHandler::GetCurrentMediaType Retrieves the current media type of the object.
IMFMediaTypeHandler::GetMajorType Gets the major media type of the object.
IMFMediaTypeHandler::GetMediaTypeByIndex Retrieves a media type from the object's list of supported media types.
IMFMediaTypeHandler::GetMediaTypeCount Retrieves the number of media types in the object's list of supported media types.
IMFMediaTypeHandler::IsMediaTypeSupported Queries whether the object supports a specified media type.
IMFMediaTypeHandler::SetCurrentMediaType Sets the object's media type.

Remarks

This interface is exposed by media-type handlers.

For media sources, get the media-type handler from the stream descriptor by calling IMFStreamDescriptor::GetMediaTypeHandler.
For media sinks, get the media-type handler by calling IMFStreamSink::GetMediaTypeHandler.

If you are implementing a custom media source or media sink, you can create a simple media-type handler by calling MFCreateSimpleTypeHandler, or you can provide your own implementation.
