Avifile Glue for mpeg2_movie started as a simple patch against heroinewarrior mpeg2_movie to utilize libavifile, however the project got out of hand and currently supports the Nuppelvideo file format for input and the MJPEGtools' mpeg2enc YUV4MPEG format for output. Originally, this project's intent was not to become a new package, but only to provide direct AVI to MPEG conversion for the GNU/Unix/Linux community until the core feature (linking against libaviplay) was integrated into the main encoder, but this goal has been abandoned. The project's current goad is to enable as many encoders as possible with the ability to read AVI, NUV, and QT.
