Grabber::setVideoNorm Method

This method sets the video of the currently active video capture device. A list of available video norms may be retrieved by calling Grabber::getAvailableVideoNorms.

Syntax:

bool setVideoNorm( const VideoNormItem& videonorm );
bool    setVideoNorm( const std::string& videonormstring );
bool    setVideoNorm( const std::wstring& videonormstring );

Parameter		Description


videonorm		Specifies the new video norm to be used by the current video capture device.
videonormstring		Specifies the name of the new video norm to be used by the current video capture device.

Return value:

true, if the video norm was set successfully, false otherwise.

Remarks:

After changing the video norm, the current video format will become invalid. A new video format has to be set with Grabber::setVideoFormat before Grabber::startLive may be called. A list of available video formats may be retrieved by calling Grabber::getAvailableVideoFormats.

Note that the active MemBufferCollection will become invalid after a call to this method and there is no MemBufferCollection set. You have to create a new collection with Grabber::newMemBufferCollection and make it the active one by calling Grabber::setActiveMemBufferCollection.
