IMFCaptureRecordSink interface (mfcaptureengine.h)
Controls the recording sink. The recording sink creates compressed audio/video files or compressed audio/video streams.
Inheritance
The IMFCaptureRecordSink interface inherits from IMFCaptureSink. IMFCaptureRecordSink also has these types of members:
Methods
The IMFCaptureRecordSink interface has these methods.
| IMFCaptureRecordSink::GetRotation Gets the rotation that is currently being applied to the recorded video stream. |
| IMFCaptureRecordSink::SetCustomSink Sets a custom media sink for recording. |
| IMFCaptureRecordSink::SetOutputByteStream Specifies a byte stream that will receive the data for the recording. |
| IMFCaptureRecordSink::SetOutputFileName Specifies the name of the output file for the recording. |
| IMFCaptureRecordSink::SetRotation Rotates the recorded video stream. |
| IMFCaptureRecordSink::SetSampleCallback Sets a callback to receive the recording data for one stream. |
Remarks
The recording sink can deliver samples to one of the following destinations:
- Byte stream.
- Output file.
- Application-provided callback interface.
If the destination is a byte stream or an output file, the application specifies a container type, such as MP4 or ASF. The capture engine then multiplexes the audio and video to produce the format defined by the container type. If the destination is a callback interface, however, the capture engine does not multiplex or otherwise interleave the samples. The callback option gives you the most control over the recorded output, but requires more work by the application.
To start the recording, call IMFCaptureEngine::StartRecord.
