This is a simple LZW-based video codec with transparency pixels and delta frames. The LZW format according to [1] is the same as in GIF but without any additional data being present in the stream (it uses dynamic index size from 9 to 12 bits, code 256 means decoder reset and code 257 means end of stream).
Each frame consists of raw frame data compressed with LZW and with pixel value 0 used for transparent pixels (or unchanged pixels in delta frames).
