FFmpeg cheat sheet for 360 video

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

How to capture, stitch and publish a 360° timelapse

Consumer ready 360° cameras are becoming ever more accessible and many people are experimenting with a variety of 360° content. Out of the many cameras on the market the Ricoh Theta S is one of the most user-friendly, turn-key solutions with lots of built-in features. However, the camera's videos are limited 1920x960 resolution and the Theta+ app only lets you create a timelapse with up to 300 or 400 images. The workaround is to use interval shooting to capture as many images as you'd like at the 5376x2688 to full resolution and then stitch them together manually into an HD video. There are few GUI solutions (especially open-source/free) which let you do this with ease. Here's how you do it:

Linux on MacBook Pro Late 2016 and Mid 2017 (with Touchbar)

Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se
