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
