Function Documentation

VWResult VIDEO_startFramesToDisk (  VWHVideo  hVideo, char *  szOutputDirectory, long  lBufferSizeLimit = VW_UNLIMITED_BUFFER )

Starts the capture of video frames to disk. Frames are written as TIFFs. This version does not write frames to disk until VIDEO_stopFramesToDisk is executed. Unless lBufferSizeLimit is set to VW_UNLIMITED_BUFFER, frames will be discarded when the buffer limit is reached. Parameters: hVideo  Handle to video camera. szOutputDirectory  Directory to write frames. start-time for video capture. lBufferSizeLimit  Limit for capture buffer in bytes. Set to VW_UNLIMITED_BUFFER for unlimited buffer size. Returns: VWResult indicating success or failure. Note: The current implementation is not very efficient and recommended only for small captures.

VWResult VIDEO_stopFramesToDisk (  VWHVideo  hVideo, int *  pnFrames = NULL )

Stops the capture of frames to disk. Parameters: hVideo  Handle to video camera. [out]  pnFrames  Pointer returning the number of frames captured. Returns: VWResult indicating success or failure.
