IAMVideoTransformComponent (Compact 2013)

3/26/2014

This interface is implemented by video transform filters that have rotation or scaling capabilities such as video decoders or color converters. The downstream filter uses this filter to control the scaling and rotation parameters of upstream filters.

Methods

In addition to the methods inherited from IUnknown this interface exposes the following methods.

Method	Description
IAMVideoTransformComponent::GetBufferParams	Returns the parameters of the buffer.
IAMVideoTransformComponent::GetRotationCaps	Returns the rotation capabilities of the stream.
IAMVideoTransformComponent::GetScalingCaps	Returns the scaling capabilities of the stream.
IAMVideoTransformComponent::GetScalingMode	Returns the mode that is used for scaling.
IAMVideoTransformComponent::GetScalingModeCaps	Returns the scaling mode capabilities of the stream.
IAMVideoTransformComponent::SetBufferParams	Sets the parameters of the buffer.
IAMVideoTransformComponent::SetScalingMode	Sets the mode that is used for scaling.

Requirements

Header	dshow.h
Library	Strmiids.lib
