yaydl 0.15.1: YouTube lost its proxy support in 0.13.0, it is back. Sorry! Also, as we download from Invidious anyway, Invidious is now an officially supported site. check-in: 02f7c03168 user: Cthulhux tags: release-0.15.1, trunk

For some video sites, `yaydl` needs to be able to parse a JavaScript on them. For this, it needs to be able to spawn a headless web browser. It requires Google Chrome, Microsoft Edge or Mozilla Firefox to be installed and running on your system.

1. Install and run [ChromeDriver](https://chromedriver.chromium.org) (if you use Chrome), the *typically* named [Microsoft Edge WebDriver](https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/) (if you use Edge) or [geckodriver](https://github.com/mozilla/geckodriver/releases) (if you use Firefox) for your platform.
2. Tell `yaydl` that you have a web driver running: `yaydl --webdriver <port> <video URL>`. (The drivers usually run on port 4444 or 9515, please consult their documentation if you are not sure.)
   *Hint:* If you need this feature regularly, you can also use the environment variable `YAYDL_WEBDRIVER_PORT` to set the port number for all further requests.
3. In theory, it should be possible to use more sites with `yaydl` now. :-)





# How to contribute code

1. Read and agree to the [Code of ~~Conduct~~ Merit](CODE_OF_CONDUCT.md).
2. Implicitly agree to the [LICENSE](LICENSE). Nobody reads those. I don't either.
3. Find out if anyone has filed a GitHub Issue or even sent a Pull Request yet. Act accordingly.
4. Send me a patch, either via e-mail (`yaydl at tuxproject dot de`), on the IRC or as a GitHub Pull Request. Note that GitHub only provides a mirror, so you'd double my work if you choose the latter. :-)

# How to set the default Invidious instance

For rather obvious reasons, including (but not limited to) the fact that Google tries to choke third-party clients, `yaydl` has been using Invidious as a wrapper since version 0.13.0. Now sometimes, the default instance hard-coded into `src/handlers/youtube.rs` *will* fail to work properly. You can use the environment variable `YAYDL_INVIDIOUS_INSTANCE` to change that: Just set it to the URI (including "https://") of [any other instance](https://docs.invidious.io/instances/).
