CMediaType.SetSampleSize method

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetSampleSize method specifies a fixed sample size, or specifies that samples have a variable size.

Syntax

void SetSampleSize(
   ULONG sz
);

Parameters

sz

Sample size, in bytes, or zero.

Return value

This method does not return a value.

Remarks

If value of sz is zero, the media type uses variable sample sizes. Otherwise, the sample size is fixed at sz bytes.
