Let’s focus on the easy part first: what we’ll be building in this tutorial. The end result will be a browser bookmarklet which can be used to convert YouTube videos to MP3s and download them. The basic interaction flow is that you click on the bookmarklet while on the page for a specific video, a new tab opens and displays a progress bar for the conversion, and then the download starts automatically as soon as it’s ready.
Building a Media Transcoder with Exodus, FFmpeg, and AWS Lambda When delivering media content over the internet, it’s important to keep in mind that factors like network bandwidth, screen resolution, and codec support will vary drastically between different devices and connections. Certain media encodings will be better suited for certain viewers, and transcoding source media to multiple formats is a must in order to ensure that you’re delivering the best possible experience to your users.
Exodus started with one simple goal in mind: to make it as easy as possible for a user to relocate working binaries from one Linux machine to another. For example, say that your laptop has a more recent version of gzip than what’s available though your server’s package manager, but that you really want to use a command-line flag that the older version doesn’t support. exodus gzip | ssh intoli.
The easiest way to install the latest Chrome version on RHEL, CentOS, and Amazon Linux versions 6.X and 7.X. # This installs Chrome on any RHEL/CentOS/Amazon Linux variant. curl https://intoli.com/install-google-chrome.sh | bash A Universal Installation Script for Google Chrome on Amazon Linux and CentOS 6 CentOS, Amazon Linux AMI, and Red Hat Enterprise Linux are three closely related GNU/Linux distributions which are all popular choices for server installations. They offer excellent performance and stability, but package availability can often be lacking.
A Bug on Linux? Why, I never! I’ve been using GNU/Linux for about fifteen years and, I’ve got to admit, it used to be pretty rough around the edges (to put it lightly). A lot can change over fifteen years though; most of the things that were once major problem areas haven’t required a second thought in years. Laptop suspension, WIFI, advanced function keys, sound, and pretty much everything else all typically “just work” these days, and this has been the case for quite a while.
It’s a common issue that scripts written and tested on GNU/Linux don’t run correctly on macOS–or vice versa–because of differences between the GNU and BSD versions of the core utils. Error messages can get drowned in the script output, making it far from obvious that something isn’t executing correctly. There are a couple of easy fixes to avoid problems like this, but they rely on some bash features that you may not be familiar with if you don’t do a ton of scripting.
