IAMVideoCompression::OverrideFrameSize

The OverrideFrameSize method overrides the frame size of a specified frame.

Syntax

  HRESULT OverrideFrameSize(
  long FrameNumber,
  long Size
);

Parameters

FrameNumber

[in] Specifies the frame number. The first frame that the filter delivers is numbered zero.

Size

[in] Specifies the maximum size of the specified frame, in bytes.

Return Values

Returns an HRESULT value. Possible values include the following.

Return code Description
S_OK Success.
E_NOTIMPL Not implemented.

Remarks

If the filter supports this method, the IAMVideoCompression::GetInfo method will return the CompressionCaps_CanCrunch flag in the pCapabilities parameter. However, this flag can also indicate that the filter supports setting the bit rate, so it does not guarantee that the OverrideFrameSize method is supported.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
