I use Ubuntu because it’s free, it’s installed on several computers in my office, and it’s easy to create a dual boot to run Windows and Ubuntu on the same computer. I spend most of my time on Windows workstations but created this tutorial using Ubuntu because Bash scripting is simpler and more powerful than Windows command-line programming. However, they get the job done and should be relatively simple, even for Bash newbies, to understand and implement. This is my way of saying that I know the scripts detailed herein aren’t the most elegant or highly optimized, particularly the script shown in Figure 5. The operative catchphrase for this tutorial is "Don’t let perfect be the enemy of the good," which, in various forms, has been attributed to Voltaire, Confucius, Shakespeare, and Mark Zuckerberg ("Done is better than perfect"). You can download all scripts shown in this article here. While this is beginner-level stuff, some familiarity with FFmpeg and Bento4 will be helpful, as will some experience with batch processing and working on the command line in Linux or Windows. You’ll learn how to run the scripts directly on folders of content and to set up a watch folder operation.
In this tutorial, you will learn how to write Bash scripts that run on Ubuntu and encode and package multiple files to HLS/DASH output using open-source tools FFmpeg and Bento4.
