Detailed Description

TechSmith Camtasia decoder.

Fourcc: TSCC

Codec is very simple: it codes picture (picture difference, really) with algorithm almost identical to Windows RLE8, only without padding and with greater pixel sizes, then this coded picture is packed with ZLib

Supports: BGR8,BGR555,BGR24 - only BGR8 and BGR555 tested
