Properties

Type Name Description
long OutputBufferCount Gets or sets the number of output buffers used by the Color Space Converter filter.The default value of this property is equal to the number of processors in the system. If you change this value, you must use a value that is greater than or equal to 1.The converter uses multithreading to speed up the conversion, using one thread per processor. Each thread uses one output buffer. This default behavior can cause problems when you process video buffers using the LEAD Video Callback Filter. If that happens, reduce the value of this property to 1.
