Enable camera module

Edit your /boot/config.txt file and make sure the following lines look like this:

start_x=1             # essential
gpu_mem=128           # at least, or maybe more if you wish
disable_camera_led=1  # optional, if you don't want the led to glow

Load bcm2835-v4l2 module

Pre-Work

Make sure you backup any personal data such as photos before applying update.
Get the latest adb tool from the Android SDK Platform-Tools package.
Add adb to your PATH environment variable or, as the instructions below assume, change into the directory containing the executable.
Enable USB debugging for your device as described here.

On Machine

Change into the directory containing the adb executable.
Download the latest OTA image (appropriate for your device) from https://developers.google.com/android/ota into the adb directory.

FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

Let's start with some basics:

ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file

	targetPos = thisComp.layer("target").toComp([0,0]); // Compensating for the missing "targetPos" variable

	box = thisComp.layer("box");
	boxTopLeft = box.toComp([0,0]);
	boxBottomRight = box.toComp([box.width,box.height]);
	// this is erroneous on their part. "deltaX" and "xDistanceToEdge" does not exist yet, commented out.
	boxAnchor = box.toComp(box.anchorPoint);// xRatio = deltaX/xDistanceToEdge;

	deltaVec = sub(targetPos, boxAnchor)
	deltaX = deltaVec[0];
