MFT_MESSAGE_NOTIFY_BEGIN_STREAMING

MFT_MESSAGE_NOTIFY_BEGIN_STREAMING

Notifies a Media Foundation transform (MFT) that streaming is about to begin.

Message Parameter

None.

Remarks

To send this message, call IMFTransform::ProcessMessage.

The client is not required to send this message. If the client sends this message, it must do so after setting all of the media types on the MFT, and before calling ProcessInput. The MFT can respond by allocating buffers or other resources. If the client does not send this message, the MFT allocates resources on the first call to ProcessInput. Therefore, sending this message can reduce the initial latency when streaming begins.

Implementation

An MFT is not required to respond to this message.

Requirements

Minimum supported client

Windows Vista [desktop apps only]

Minimum supported server

Windows Server 2008 [desktop apps only]

Header

Mftransform.h
