Ever found yourself with two or more video files that you need to merge into one? Check out transcode, a package of command line utilities for processing video files. AVI files, for instance, are easily merged using the command avimerge.
I could obtain only the bittorrent file from the transcode website and compilation is not easy due to the requirement for several video dev libraries. On Ubuntu, a simple “sudo apt-get install transcode transcode-doc” does the trick.
