[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 put_Interleaving method sets the audio preroll time and the frequency of interleaving for an AVI file.

Syntax

HRESULT put_Interleaving(
  [in] const REFERENCE_TIME *prtInterleave,
  [in] const REFERENCE_TIME *prtPreroll
);

Parameters

[in] prtInterleave

The approximate duration of each interleaved group of audio or video chunks, in 100-nanosecond units. The exact amount of interleaving is also affected by the interleave mode, which is specified by calling IConfigInterleaving::put_Mode.

[in] prtPreroll

The amount of audio data, in 100-nanosecond units, that is written to the file before the first video frame.

Return value

Returns an HRESULT value that depends on the implementation of the interface.

Remarks

An audio preroll of 750 milliseconds is recommended when authoring a file for distribution.

If you do not call this method, the default value for prtInterleave is 1000 milliseconds. The smaller the number, the larger the resulting file.
