AVI Compressor Filter

The AVI Compressor filter enables Video Compression Manager (VCM) codecs to join a filter graph. Each codec appears as a separate instance of the filter. You cannot directly create this filter with CoCreateInstance. Instead, you must use the system device enumerator. For more information, see Using the System Device Enumerator.

The filter's input pin connects to filters that output uncompressed video data, such as video capture filters or the AVI Splitter Filter. The filter's output pin typically connects to a MUX filter, such as the AVI Mux Filter.

If the codec supports an old-style VFW configuration dialog box or About dialog box, an application can display it using the IAMVfwCompressDialogs interface.

Note  MPEG compressors are never implemented as VCM codecs, but only as native DirectShow filters.
