Convert mp4 to mp3 + calling command line programs from Processing
Hi! I was asked how to get the audio out of a video file, so I shared this little program:
It also serves as an example of calling any command line program. There's thousands of command line programs to do all kinds of audio, video and image manipulation. It's like a massive Processing library :) A bit geeky, but powerful.
Some media related command line tools:
- SoX − Audio manipulation. http://sox.sourceforge.net/sox.html
- ImageMagick® - Transform and compose images. http://imagemagick.org
- Gifsicle - Create GIF animations. https://www.lcdf.org/gifsicle/
- FFmpeg - Manipulate video and audio. http://ffmpeg.org/
What other tools should be in this list?

Potrace is a good raster to vector tool that I have used in Processing: http://potrace.sourceforge.net/
Thanks @Potrace! That can be very useful for vectorizing user hand made drawings :)
Thank for the useful tips. For easier conversion, this program is also helpful:http://www.videoconverterfactory.com/tips/shn-converter.html It can deal with kinds of video/audio formats and convert them reciprocally。
@HottFallen ok, but we were talking about command line programs that you can integrate with Processing. There's thousands of programs with a GUI to convert media files, but you can't run them from Processing nor are they cross-platform.
