- The MVC2 (Motion Video Compressor 2) compression algorithm is implemented
- as one of the codecs in the Compression Library (CL). Its scheme
- identifier is CCCCLLLL____MMMMVVVVCCCC2222____SSSSOOOOFFFFTTTTWWWWAAAARRRREEEE, and is accessible through the standard CL
- API. For an overview of the basic library calls and parameters, see
- CLintro(3dm).
-
- Compression involves a simple block coding heuristic based on various
- perceptual criteria. The amount of compression is guided by setting the
- following parameters. In each case, a higher threshold results in more
- compression.
-
- CCCCLLLL____MMMMVVVVCCCC2222____LLLLUUUUMMMMAAAA____TTTTHHHHRRRREEEESSSSHHHHOOOOLLLLDDDD
- Type: CL_RANGE_VALUE
- The threshold used to determine which blocks are encoded as constant
- values. Range is 0 to 255.
-
- CCCCLLLL____MMMMVVVVCCCC2222____CCCCHHHHRRRROOOOMMMMAAAA____TTTTHHHHRRRREEEESSSSHHHHOOOOLLLLDDDD
- Type: CL_RANGE_VALUE
- The threshold used to determine which blocks are encoded with
- luminance only, or with chroma as well. Range is 0 to 255.
-
- CCCCLLLL____MMMMVVVVCCCC2222____EEEEDDDDGGGGEEEE____TTTTHHHHRRRREEEESSSSHHHHOOOOLLLLDDDD
- Type: CL_RANGE_VALUE
- The threshold used to determine which blocks are encoded as high
- activity regions. This value should be at least as large as
- CL_MVC2_LUMA_THRESHOLD. Range is 0 to 255.
-
- Decompression may be adjusted with the following parameter.
-
- CCCCLLLL____MMMMVVVVCCCC2222____BBBBLLLLEEEENNNNDDDDIIIINNNNGGGG
- Type: CL_ENUM_VALUE
- This value may be CL_MVC2_BLENDING_OFF or CL_MVC2_BLENDING_ON.
- If blending is enabled, edges of tiles will be smoothed on
- decompression so that blocking artifacts are reduced.
