How to use VLC to watch m3u8 playlist at URL with custom HTTP referrer and user agent

Imagine this: it's Sunday afternoon at 1pm, and you want to watch some live content. But you don't have a TV subscription. So you do a little Googling, and eventually you find yourself on a sketchy website where you can watch the content you're looking for. But while the website has a video player, it's surrounded by advertisements, and probably a cryptominer too. You don't want this website eating your CPU for 2 hours while you're watching your favorite Sunday afternoon content.

Wouldn't it be nice if you could watch that video in VLC instead? Then you can close the sketchy website and still watch your content. It's like having your cake and taking a bite of it too!

Here's how you do it:

  1. Capture the m3u8 request in dev tools. Open the site (or just the iframe, if possible) in DevTools and click "play." Search the network tab for m3u8 and grab the first request.

  2. Run VLC with command line flags to set the User Agent and Referrer. From the request body, you need to copy the requested URL,

inherit environment variables from PID 1

You can inherit the environment variables from PID 1 by iterating over the list of null-terminated strings in /proc/1/environ, parsing the first characters up to the first = as the variable name, setting the remaining value as that variable, and exporting it.

The Code Snippet

This works with multiline environment variables, and environment variables with arbitrary values, like strings, including = or JSON blobs.

Paste this in your current terminal session to inherit the environment variables from PID 1:

"Spotify cannot play the current song" - So restart it! (restart spotify from mac command line)
#!/usr/bin/env bash
# I got sick of constantly getting the error from spotify that it cannot play
# the current song. It was really annoying to have to quit, open spotlight,
# Type "spot" and accidentally open spotlight system preferences, wait for spotify
# to open, etc...
# This script, on a mac, uses osascript to quit and relaunch spotify and press play
osascript -e 'tell application "Spotify" to quit'
