Inputs/Outputs
Compatibility

AVI session in

Reference to the AVI file output from the Create AVI File (DirectShow) node or the Open AVI File (DirectShow) node.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error

If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

AVI session out

AVI session out is the reference to the AVI file.

frame data

Cluster containing information about the AVI.

width

Image width.

height

Image height.

frames per second

AVI frames per second.

codec

Codec used to create the AVI file.

has data?

Data associated with each image in the AVI file.

number of frames

Number of frames contained in the AVI file.

image type

Type of image used in the AVI file.

Name	Value	Description
Grayscale (U8)	0	The image is grayscale U8.
Grayscale (I16)	1	The image is grayscale I16.
Grayscale (SGL)	2	The image is grayscale SGL.
Complex (CSG)	3	The image is Complex CSG.
RGB (U32)	4	The image is RGB U32.
HSL (U32)	5	The image is HSL U32.
RGB (U64)	6	The image is RGB U64.
Grayscale (U16)	7	The image is grayscale U16.

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

error in does not contain an error	error in contains an error

If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.
