◆ Movie2GetUseMetadata()

long Movie2GetUseMetadata	(	MOVIE2RECORDER	Handle,
		BOOL &	Use
	)

Query whether meta data are currently being written.

The Movie2RegisterMetaDataCallback has to be registered with which the MetaData can be written to the AVI file.

Meta data are (ANSI-) strings with up to 64k characters, one per image being recorded. For example, the MetaData can be used to save the corresponding timestamp as a string for every recorded frame within the AVI container.
To read out the MetaData you can implement the CVB Notify Interface (INotify) of the Driver.dll in your own application. If you prefer the Grabber OCX you can use the ImageNotificationString Event. As examples the VCMovie2PlayerExample and the CSMovie2PlayerExample are included in Movie2.

Note: Some media players or AVI Editors may get confused by the presence of a text stream in the AVI container. When an AVI Editor does not support the text stream the MetaData is lost after editing the AVI file. For Example VirtualDub with DirectStreamCopy writes only the text of the first frame to all other frames.
Our Movie Interactive 2 is the only application we know which can handle text streams as MetaData. So if you want to recompress your recorded movie and don't want to lose the MetaData use Movie Interactive 2.

Parameters

[in]	Handle	Handle of recorder object on which to query.
[out]	Use	`TRUE` if metadata are to be written, `FALSE` otherwise.

Returns: 0 : OK
< 0: an error occurred

Returns: 0 : OK

Win64

Examples:: Delphi - Delphi Movie2 Example
Visual C++ - VC Movie2 Example

◆ Movie2PreStartRecording()

long Movie2PreStartRecording ( MOVIE2RECORDER Handle )

Prepare the start of AVI recording.

This method may be called any time prior to Movie2StartRecording to speed up the initialization process and allow the recorder to react to the "start" signal more promptly. If it has not been called prior to Movie2StartRecording, Movie2StartRecording will call Movie2PreStartRecording to do the necessary initializations.

Parameters

[in] Handle Handle of recorder object for which to prepare recording start.

Returns: 0 : OK

◆ Movie2SetFrameRate()

long Movie2SetFrameRate	(	MOVIE2RECORDER	Handle,
		double	FramesPerSecond
	)

Set the frame rate with which the recoding engine should record the video signal.

Note: This is usually just an information inside the resulting video file. If you specify a frame rate of 25 here, but your signal was recoded at 30 fps then playback will happen with 25 frames per second - which is visibly slower than real time.
So this frame rate property has no connection to the rate at which the video signal was acquired, and it is the responsibility of the programmer writing a Movie2 application to set the frame rate to a value that reasonably represents the frame rate of his acquisition device (if unsure, consult the manuals of your acquisition device(s) for details about the frame rate or contact the vendor.

Parameters

[in]	Handle	Handle of recorder object for which to set the value.
[in]	FramesPerSecond	Frame rate to be set.

		Movie2_SyncMode	Mode
	)

Set the synchronization mode to be used by the Movie2 recording engine.

Note: When not working in Event driven mode (Movie2AddFrame), then the Movie2_SyncMode tells when the client should be informed about the arrival of a new image: Movie2_SyncAfterCopy means that the ImageSnapped events will fire after the copy Movie2_SyncBeforeCopy mean that they will fire before the copy.

Parameters

◆ Movie2SetTargetFileName()

long Movie2SetTargetFileName	(	MOVIE2RECORDER	Handle,
		const char *	szFileName
	)

Set the name of the file into which the AVI sequence is to be recorded.

Attention: If the target file exists it will be overwritten.

Parameters

[in]	Handle	Handle of recorder object.
[in]	szFileName	Name of the AVI file to be generated.

Returns: 0 : OK
< 0: an error occurred

◆ Movie2SetTargetFileNameW()

long Movie2SetTargetFileNameW	(	MOVIE2RECORDER	Handle,
		const wchar_t *	szFileName
	)

Set the name of the file into which the AVI sequence is to be recorded.

Attention: If the target file exists it will be overwritten.

Parameters

[in]	Handle	Handle of recorder object.
[in]	szFileName	Name of the AVI file to be generated.

◆ Movie2SetUseMetadata()

long Movie2SetUseMetadata	(	MOVIE2RECORDER	Handle,
		BOOL	Use
	)

Specify whether or not meta data should be recorded while writing an AVI file.

Note: Note that not all engines may support meta data and others may support meta data depending on the recording mode only. The callback has to be registered with Movie2RegisterMetaDataCallback with which the MetaData can be written to the AVI file.

Meta data are (ANSI-) strings with up to 64k characters, one per image being recorded. For example, the MetaData can be used to save the corresponding timestamp as a string for every recorded frame within the AVI container.
To read out the MetaData you can implement the CVB Notify Interface (INotify) of the Driver.dll in your own application. If you prefer the Grabber OCX you can use the ImageNotificationString Event. As examples the VCMovie2PlayerExample and the CSMovie2PlayerExample are included in Movie2.

Note: Some media players may get confused by the presence of a text stream in the AVI container. When an AVI Editor does not support the text stream the MetaData is lost after editing the AVI file. For Example VirtualDub with DirectStreamCopy writes only the text of the first frame to all other frames.

Parameters

[in]	Handle	Handle of recorder object on which to set.
[in]	Use	`TRUE` if metadata are to be written, `FALSE` otherwise.

Returns: 0 : OK
< 0: an error occurred

◆ Movie2ShowCodecPropertyPage()

long Movie2ShowCodecPropertyPage	(	MOVIE2RECORDER	Handle,
		HWND	hwndOwner
	)

If possible, display the property page(s) of the currently selected video compression codec (the one set by the last call to Movie2SetCompressorIndex).

Note: To display the property page is not possible while the recorder is recording.

Parameters

[in]	Handle	Handle of recorder object.
[in]	hwndOwner	Handle of parent form.

Returns: 0 : OK

◆ Movie2StartRecording()

long Movie2StartRecording ( MOVIE2RECORDER Handle )

Start continuous recording of AVI data into a file according to the settings made before this method has been called.

If you want to speed up the Movie2StartRecording you can use Movie2PreStartRecording to initialize the recording.

Parameters

[in] Handle Handle of recorder object for which to start recording.

Returns: 0 : OK
