Applications can turn compression on and off by calling VDSetCompressionOnOff . Applications can obtain the digitizer's image description structure by calling the VDGetImageDescription function. Applications can set the digitizer's time base by calling the VDSetTimeBase function. All of the digitizing functions described in this section support only asynchronous digitization. That is, the video digitizer works independently to digitize each frame.
Applications are free to perform other work while the digitizer works on each frame.
The video digitizer component manages its own buffer pool for use with these functions. VDGetCompressionTypes For current documentation, see VDGetCompressionTypes .
