FramesAvailable

Indicate number of frames available in memory buffer

Description

The FramesAvailable property indicates the total number of frames that are available

in the memory buffer. When you extract data, the object reduces the value of the

FramesAvailable property by the appropriate number of frames. You use the getdata

function to extract data and move it into the MATLAB workspace.

Note When you issue a start command, the video input object resets the value of the

FramesAvailable property to 0 (zero) and flushes the buffer.

To view the total number of frames that have been acquired since the last start

command, use the FramesAcquired property.
