An image processing stage that generates transitions between two input
Set this to control the input size of the image. Typically this is
called by the component itself when this port is tunnelled with an
appropriate output port. The image format must be YUV420 packed
planar. nSliceHeight must be nFrameHeight rounded up to
a multiple of 16. nStride must be nFrameWidth rounded
up to a multiple of 32. After one input port is enabled, both the
second input port and the output port must be set to the same input
|| Get this to show what the output size will be. Set to alter the number
of buffers to be used only.
|| Used to set and start the next transition effect. Setting this config
may fail if the component is either starting or finishing a transition
effect. The last input port to be enabled is used as the stop image.
|| Query / set the internal representation of transitions. This allows
fine-grained control of the exact effect, frame rates, and transition
|| Used to set up proprietary communication with the next component.

|| Query / set the image format used on this port. Currently all ports
only support the YUV420PackedPlanar uncompressed image format.
|| Used to configure the memory size for the internal buffer used to
allocate output frames. It will default to the size of the output
frame, with num_pages as 3. If this is set before either input
port is configured, it will pre-allocate the buffers used for input
images as well as the output pool, which gives better memory
allocation performance during slideshows.
