It is not free software, but you can download it without charge here: http://developer.lizardtech.com/ . To enable file creation capability you need encoding SDK (ESDK). You should contact [http://www.lizardtech.com LizardTech] to obtain it. The DSDK is distributed in binary form and if you are using GCC, please, ensure that you have the same compiler as was used for DSDK compilation. It is C++ library, so you may get incompatibilities in C++ name mangling among different GCC versions (2.95.x and 3.x).
