[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The SetOutputCompatibilityIndex method sets the AVI index format.

Syntax

HRESULT SetOutputCompatibilityIndex(
  [in] BOOL fOldIndex
);

Parameters

[in] fOldIndex

Specifies one of the following values:

Value	Description
TRUE	Create an AVI 1.0 index, as well as an AVI 2.0 index.
FALSE	Create an AVI 2.0 index, but not an AVI 1.0 index.

Return value

Returns S_OK if successful, or an error code otherwise.

Remarks

The AVI Mux filter always creates an AVI 2.0 index ('indx' format). If the value given in fOldIndex is TRUE, the AVI Mux also creates an AVI 1.0 index ('idx1' format), for backward compatibility with Video for Windows.

The AVI 2.0 index format allows for larger files, incremental growth of files, and minimized disk seeks.
