TIEMediaFoundationSourceReader.PushNotifyReceiver

Declaration

procedure PushNotifyReceiver(notifyReceiver: IIEMediaFoundationReaderNotifyReceiver);

Description

Adds a notify receiver. A notify receiver receives notifications like "start capturing", "new frame", "end of stream".

Applications can use this method to add an audio renderer before capture begins.

Note: TImageEnView is setup as receiver of TIEMediaFoundationSourceReader in order to deliver OnMediaFoundationNotify events.

Example

// Add the audio renderer
audioStreamindex := ImageEnView1.IO.MediaFoundationSourceReader.IndexOfFirstStream(mmf_AUDIO_STREAM);
ImageEnView1.IO.MediaFoundationSourceReader.PushNotifyReceiver( TIEMediaFoundationAudioRenderer.Create(audioStreamIndex) );
ImageEnView1.IO.MediaFoundationSourceReader.StartCapture();

// Remove the audio renderer
ImageEnView1.IO.MediaFoundationSourceReader.StopCapture();
ImageEnView1.IO.MediaFoundationSourceReader.PopNotifyReceiver();
