This codec was developed by TechSmith and used in their screen capturing products.
Frame format
This codec operates on 16x8 macroblocks.
0 - frame type (1- coded, 0 - skip frame) 1 - luma quantiser? 2 - chroma quantiser? 3 - ??? [macroblock properties] [macroblock slices]
Macroblock properties:
4 bytes LE - chunk size rest - RLE-coded properties in bytes in form (val << 6) | (count)
Macroblock slices begin with slice size. If the first byte is odd, then it's the full size. Otherwise read whole 32-bit word and divide it by two in order to obtain real macroblock data size.
