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

| MS5541 Pressure Sensor calwords readout | |
| This program will read your MS5441 or compatible pressure sensor every 5 seconds and show you the calibration words, the calibration factors, | |
| the raw values and the compensated values of temperature and pressure. | |
| Once you read out the calibration factors you can define them in the header of any sketch you write for the sensor. | |
| Pins: | |
| MS5541 sensor attached to pins 10 - 13: | |
| MOSI: pin 11 |

| Likely not useful to anyone else, but just putting it out there. | |
| This script will take a directory of GeoTIFFs and merge them together without issues. | |
| This script simply decompresses the files, runs nearblack to remove pseudo-black borders caused by compression, and then uses gdalwarp to stitch the files together. | |
| The script is designed to use the minimal amount of disk space possible -- it cleans up each file after decompression and continually merges with a master image. | |
