DiskLogger

AVI File
A MATLAB AVI file object specifies the name and other characteristics of an AVI file.
For example, you can use AVI file object properties to specify the codec used for data
compression and the desired quality of the output. For complete information about the
AVI file object and its properties, see the avifile documentation.
Note Do not use the variable returned by the avifile function to perform any operation
on an AVI file object while it is being used by a video input object for data logging. For
example, do not change any of the AVI file object properties, add frames, or close the
object. Your changes could conflict with the video input object.
When the video input object finishes logging data to disk, the AVI file object remains
open. The video input object does not open or close an AVI file object used for logging.
The video input object, however, does update the Width, Height, and TotalFrames
fields in the AVI file object to reflect the current acquisition settings.
After Logging and Running are off, it is possible that the DiskLogger might still be
writing data to disk. When the DiskLogger finishes writing data to disk, the value of
the DiskLoggerFrameCount property should equal the value of the FramesAcquired
property. Do not close or modify the DiskLogger until this condition is met.
Note: The peekdata function does not return any data while running if in disk logging
mode.
