EasyBMPtoAVI is a cross-platform (Linux, Windows, OSX, Solaris..), easy-to-use application to convert a series of BMP images of any bit depth to an AVI movie file. EasyBMPtoAVI supports both command-line and interactive use, and a GUI version is planned.
you need to download the EasyBMP project first. Then copy *.h and *.cpp into the sources of this project before typing make. Then it's a dreeeeeam!
