);

Remarks
The handler for writing AVI files does not accept format changes. Besides setting the initial format for a stream, only changes in the palette of a video stream are allowed in an AVI file. The palette change must occur after any frames already written to the AVI file. Other handlers might impose different restrictions.
The argument pavi is a pointer to an IAVIStream interface.
