About The Project

Object: Exporter Object
Name: Video Exporter
Input: Native Image Connector named „IMAGE_RGBa8“
Output:

Container	AVI
Codec	MJPG

Properties:

Property Name	Type	Default	Description
Allow Encoding	bool	true	true: allow encoding false: stop encoding
Frames per second	uint32_t	25	FPS of the exporting video; every incoming packet is one frame
Output Filename	std::string	„Output“	Name of the exporting video
Output Directory	std::string	„C:\“	Loaction to the output directory
Use Numeration as suffix	bool	true	true: Add counter to the end of the filename false: Use only „Output Filename“ property as name
Timeout[ms]	uint32_t	2000	Maximum number of milliseconds between incoming packages. If the delay is greater the export ends.

By default after creation when data packets first come in over a connection they will be exported. After the export of a video is finished the property Allow Encoding has to be manually set to true to start another video export or a new connection has to be established.

Video export ends automatically if the delay between two packets is greater than the value of proptery Timeout[ms] or the connection to the input connector is severed.

When property Use Numeration as suffix is true the exported video on default settings is C:\Output001.avi. If it is false the video is C:\Output.avi.

Note If no file can be generated e.g. due to missing permissions at the target location there will be no warning. The only indication is that the counter gets incremented for every incoming package that could not be written and then the first working export after will start at a higher number than 001.

Usage

Right-click in the node graph editor of the configuration manager and choose Exporter Objects -> Video Exporter as seen below.

By clicking on the Video Exporter MO the output directory and output filename can be edited in the property list.
