Removes the package, 'packagename' in the example ,from your system. '-R' is the actual removal option, 'n' is for removing backup configuration files saved by pacman, and 's' is for removing the dependencies of the given package which are not required by other packages. pacman does not remove configuration files, etc. created by the package.

Revert a Digital Cinema Package back to a ProRes file, to (kind of) verify if the DCP creation wen't well Show Sample Output
0ffmpeg -i VIDEODCP.mxf -i AUDIODCP.mxf -vcodec h264 -acodec aac reverse-prores.mov -
This command KIND OF play a Digital Cinema Package files through VLC using FFMPEG realtime encoding. For a smooth playback you'll need a REALLY powerful computer, possibly a rig with two or more processors (really!) Otherwise, it may be better to just convert the DCP to ProRes and playing it afterwards.

The Piano Phase piece, by Steve Reich is a minimalist composition which is played on two pianos played at slightly different tempos, a task that's very difficult to accomplish by human players. The auditive effects produced by the cell displacement produce beautiful patterns. See https://en.wikipedia.org/wiki/Piano_Phase . My rendered version: https://ydor.org/SteveReich/piano_phase.mp3 Requires sox to be installed on the system. There are multiple videos on youtube showing different approaches and experiences to this interpretation. There is also a synthesized version. Even if Bash can behave as a powerful pianist, a simple threaded version leaves full room to several time glitches and even negative displacements, the same issues that human pianists experience when playing the piece. The older the computer, the better the chaos added to the result due to the CPU load. Apparently that's the reason Steve Reich composes pieces such as this. Without further ado, please give a warm welcome to the Bash minimalist player on synthesized two-threaded pianos. Please turn off your cellphones.
