Capturing AVIs
The functions of the uc480_tools.dll enable you to save images captured with the DCx camera as
sequences to an AVI file. In order to reduce the file size, the single frames are stored in the AVI
container using an adjustable JPEG compression. It is possible to extract single frames from the
AVI file.
AVI Capture Workflow
isavi_InitAVI()
Initialises the DCx camera AVI interface.
isavi_ExitAVI()
Terminates and closes the DCx camera AVI interface.
isavi_OpenAVI()
Opens an AVI file for capturing.
isavi_CloseAVI()
Closes an AVI file.
isavi_GetAVIFileName()
Returns the name of the current AVI file.
The following settings should also be done prior to starting the recording.
isavi_SetFrameRate()
Sets the frame rate of the AVI video.
isavi_SetImageQuality()
Sets the compression level / image quality of the AVI
video.
isavi_SetImageSize()

Once the AVI file has been created, captured images are placed in a buffer. Then, the images are
compressed and added to the AVI file which is stored on the hard disk. These operations are not
performed in the same thread as the capturing process. If you capture more images while a
compression or write operation is in progress, the new images will be discarded.
