IAMMediaStream interface (amstream.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Note This interface is deprecated. New applications should not use it.
IAMMediaStream interface handles the internal connections between Microsoft DirectShow filters and filter graphs in applications that use multimedia streaming. This enables applications to automatically negotiate the transfer and conversion of data from the source to the application without having to write code to handle the connection, transfer of data, data conversion, and actual data rendering or file storage. This provides a uniform and predictable method of data access and control.
This interface isn't intended for implementation or use by application developers.
Inheritance
The IAMMediaStream interface inherits from IMediaStream. IAMMediaStream also has these types of members:
Methods
The IAMMediaStream interface has these methods.
| IAMMediaStream::Initialize Note This interface is deprecated. New applications should not use it. The Initialize method creates and initializes a new media stream with the specified stream type and purpose ID. |
| IAMMediaStream::JoinAMMultiMediaStream Note This interface is deprecated. New applications should not use it. The IAMMultiMediaStream::AddMediaStream method calls this method, which adds the specified media stream to the current multimedia stream. |
| IAMMediaStream::JoinFilter Note This interface is deprecated. New applications should not use it. The JoinFilter method connects a media stream to the Media Stream filter, which is used internally by the multimedia stream object. Applications should not call this method. |
| IAMMediaStream::JoinFilterGraph Note This interface is deprecated. New applications should not use it. The JoinFilterGraph method connects a media stream filter to a filter graph. |
| IAMMediaStream::SetState Note This interface is deprecated. New applications should not use it. The SetState method sets the filter state. |
