Detailed Description

innoHeim/Rsupport Screen Capture Codec decoder

Fourcc: ISCC, RSCC

Lossless codec, data stored in tiles, with optional deflate compression.

Header contains the number of tiles in a frame with the tile coordinates, and it can be deflated or not. Similarly, pixel data comes after the header and a variable size value, and it can be deflated or just raw.

Supports: PAL8, BGRA, BGR24, RGB555
