IMFMediaEngineSrcElements interface (mfmediaengine.h)
Provides the Media Engine with a list of media resources.
Inheritance
The IMFMediaEngineSrcElements interface inherits from the IUnknown interface. IMFMediaEngineSrcElements also has these types of members:
Methods
The IMFMediaEngineSrcElements interface has these methods.
| IMFMediaEngineSrcElements::AddElement Adds a source element to the end of the list. |
| IMFMediaEngineSrcElements::GetLength Gets the number of source elements in the list. |
| IMFMediaEngineSrcElements::GetMedia Gets the intended media type of an element in the list. |
| IMFMediaEngineSrcElements::GetType Gets the MIME type of an element in the list. |

Remarks
The IMFMediaEngineSrcElements interface represents an ordered list of media resources.
This interface enables the application to provide the same audio/video content in several different encoding formats, such as H.264 and Windows Media Video. If a particular codec is not present on the user's computer, the Media Engine will try the next URL in the list. To use this interface, do the following:
- Create an implementation of this interface.
- Initialize your implementation with a list of URLs. Optionally, provide MIME types and media query strings for each URL.
- Call the IMFMediaEngine::SetSourceElements method.
