Open source video captioning on Linux

In a perfect world, all videos would have transcripts, and live videos would have captioning. It’s not just a requirement for people without hearing to be able to participate in pop culture and video chats, it’s a luxury for people with hearing who just prefer to read what’s been said. Not all software has captioning built-in though, and some that does relies on third-party cloud services to function. Live Captions is an application for the Linux desktop that provides instant, local, and open source captioning for video.

How to install and run youtube-dl from actual source code, so that you can apply patches as needed

If you use the program youtube-dl, you may have noticed that from time to time things stop working. Usually it’s because something changes on a site and youtube-dl needs to be patched to deal with it. But what sometimes happens is that someone will submit a patch and then the youtube-dl developers will ignore that patch for many months before they finally get around to merging it into the program. The speed at which the youtube-dl developers fix issues with sites can seem glacial at times.

What’s frustrating is that if you browse through the issues section of the youtube-dl support area using an appropriate search term, you may find the fix for your problem, and maybe it’s just been sitting there for quite some time. But, since youtube-dl is distributed as a compiled binary you may think you have no way to apply it. But that’s not really true – at its core, the entire program is simply a multitude of Python scripts, and it can be run without first being compiled. And if you use it that way, then you can apply patches as needed to any of the python modules, whether they are patches you have written or patches that you have found in the issues area, or elsewhere on the Internet.

So here is how you can install and use youtube-dl using actual source code.

Install and Use ffmpeg in Ubuntu & Other Linux [Full Guide]

ffmpeg is a CLI (command line based) utility for processing media files. It is a framework with a multitude of features and, because of it’s open source license, it is the base for many widespread apps such as VLC, YouTube, iTunes and many more. A number of Linux video editors use ffmpeg underneath the GUI.

What I love even more about ffmpeg is that it can be used on it’s own to accomplish many processing tasks in a very simple manner (with one or two commands). However, it’s a very powerful program that can be used in more complex ways and even replace an editing workflow.

In this ffmpeg tutorial, I’ll show you how to install ffmpeg and I’ll be covering it’s different uses. I’ll even get into some more complex features.
