HandBrake
HandBrake is a free and open-source video transcoder, originally developed in 2003 by Eric Petit (aka "titer" from his SVN repository username) to make ripping a film from a DVD to a data storage device easier. Since then, it has undergone many changes and revisions.
HandBrake is available for Windows, OS X (Mac), and Ubuntu from its official web site, although it is possible to compile it for Debian, Linux Mint, Fedora, CentOS, or RHEL. HandBrake uses third-party libraries such as x264, FFmpeg, Libav, and FAAC, the last of which is slated for removal due to licensing issues.
History
Early versions
HandBrake was originally developed by Eric "titer" Petit in 2003 as software for the BeOS, before porting it to other systems. He continued to be the primary developer until April 2006, when the last official subversion was submitted. "titer" continued to be active on the HandBrake forum for a brief period after, until contact was lost. Since May–June 2006, no one in the HandBrake community was successful in contacting "titer" and no further code changes were officially made.
