This is a collection of working commandline examples to show how one could use FFMpeg and VLC for live transcoding of video streams. All examples have been tested on OSX 10.7.5 with FFMPeg 1.1.3 and VLC 2.0.5 in early 2013.

| Sid Meier's 10 Rules of Game Design | |
| 1. Choose a topic you have a passion for. Game Design is about creativity. | |
| 2. Do research after the game is done. Tap into the player’s brain. | |
| 3. Define your axioms, refine your axioms. Prototype, prototype, prototype; sit in all the chairs. | |
| 4. Double it or cut it in half. You are more wrong than you think. |
