+ <entry>Video composer (blender). An entity capable of video
+ composing must have at least two sink pads and one source
+ pad, and composes input video frames onto output video
+ frames. Composition can be performed using alpha blending,
+ color keying, raster operations (ROP), stitching or any other

+ <entry>Video pixel formatter. An entity capable of pixel formatting
+ must have at least one sink pad and one source pad. Read
+ pixel formatters read pixels from memory and perform a subset
+ of unpacking, cropping, color keying, alpha multiplication
+ and pixel encoding conversion. Write pixel formatters perform
+ a subset of dithering, pixel encoding conversion and packing
+ and write pixels to memory.

+ enconding conversion must have at least one sink pad and one
+ source pad, and convert the encoding of pixels received on
+ its sink pad(s) to a different encoding output on its source
+ pad(s). Pixel encoding conversion includes but isn't limited

+ <entry>Video look-up table. An entity capable of video lookup table
+ processing must have one sink pad and one source pad. It uses
+ the values of the pixels received on its sink pad to look up
+ entries in internal tables and output them on its source pad.
+ The lookup processing can be performed on all components
+ separately or combine them for multi-dimensional table
+ lookups.

+ at least one sink pad and one source pad, and scale the
+ video frame(s) received on its sink pad(s) to a different
+ resolution output on its source pad(s). The range of
+ supported scaling ratios is entity-specific and can differ
+ between the horizontal and vertical directions (in particular
+ scaling can be supported in one direction only). Binning and
+ skipping are considered as scaling.
