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

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

GeoTIFFs -> One Big GeoTIFF
View merge-geotiff.py
"""
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.
