/**
*
* Video encoder class.
*
* Usage:
*
* Create encoder object. Optionally
* set quality and key-frame frequency. Call Start().
* Call GetOutputSize() to identify maximum possible
* size of compressed frame. Allocate buffer of this size.
* Pass it as 'dest' in calls to EncodeFrame(). At the end
* call Stop(). Do not forget to delete the object.
*
* Some codec DLLs have be controlled by special codec-specific
* parameters. In Windows you can set them from codec configuration
* dialog, but since we are completely GUI-independent, we'll need
* an internal method to set them. Currently it is done by calling
* static func SetExtendedAttr(), which takes FOURCC of codec,
* name of parameter and its integer value. Complete list of
* supported attributes can be retrieved as GetCodecInfo().encoder_info.
* SetExtendedAttr() should be called before object creation,
* because values for these attributes are typically stored in
* registry and read by codec during object creation.
