IAMVideoCompression::get_WindowSize (Compact 2013)

3/26/2014

This method retrieves the number of frames over which the compressor will maintain the average data rate.

For example, assuming a data rate of 100K/sec and a frame rate of 10 frames per second, if the window size is 1, then every frame will be 10K or less. If the window size is 5, then every five consecutive frames will average 10K per frame, but individual frames may exceed this size.

The default window size is 1.

Syntax

HRESULT get_WindowSize(
  DWORDLONG* pWindowSize
);

Parameters

• pWindowSize
  [out] Pointer to a DWORDLONG variable that receives the window size, expressed as a number of frames.
