unsigned short movieWidth, unsigned short movieHeight,
unsigned movieFPS, Boolean packetLossCompensate)

// Ignore subsessions without a data source:
FramedSource* subsessionSource = subsession->readSource();

// If "subsession's" SDP description specified screen dimension
// or frame rate parameters, then use these.

}
AVISubsessionIOState* ioState

}
// Begin by writing an AVI header:
addFileHeader_AVI();
