This method overrides the frame size of a specified frame.

Syntax 

HRESULT OverrideFrameSize(
  long 
FrameNumber,
  long 
Size
);

Parameters

FrameNumber

[in] A long value that specifies the frame number. The first frame that the filter delivers is numbered zero.

Size

[in] A long value that specifies the maximum size of the specified frame, in bytes.

Return Value

Returns an HRESULT value. The following table shows some of the possible return values.

Value Description

S_OK

Success.

E_NOTIMPL

Not implemented.

Remarks

If the filter supports this method, the IAMVideoCompression::GetInfomethod will return the CompressionCaps_CanCrunch flag (see CompressionCaps) in the pCapabilitiesparameter. However, this flag can also indicate that the filter supports setting the bit rate, so it does not guarantee that the OverrideFrameSizemethod is supported.
