yet another youtube (and more) down loader

% yaydl "https://www.youtube.com/watch?v=jNQXAC9IVRw"

How? What? Why?

% yaydl --help

Features

  • Can download videos.
  • Can optionally keep only the audio part of them.
  • Could convert the resulting file to something else (requires ffmpeg).
  • Comes as a single binary (once compiled) - take it everywhere on your thumbdrive, no Python cruft required.

Currently supported sites

  • YouTube.com
  • Vimeo.com
  • VOE.sx
  • WatchMDH.to (broken as of Oct 2021; you can help!)
  • VIVO.sx
  • Vidoza.net

There is an easy way to add more supported sites, see below for details.

Non-features

The list of features is deliberately kept short:

  • No output quality choice. yaydl assumes that you have a large hard drive and your internet connection is good enough, or else you would stream, not download.
  • No complex filters. This is a downloading tool.
  • No image file support. Videos only.

Missing features (patches are welcome)

  • yaydl currently ignores video meta data (except the title) unless they are a part of the video file.
  • Playlists are not supported yet.

How to contribute code

  1. Read and agree to the Code of ~~Conduct~~ Merit.
  2. Implicitly agree to the 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. :-)

If you do that well (and regularly) enough, I'll probably grant you commit access to the upstream Fossil repository.

Add support for new sites

  1. Implement definitions::SiteDefinition as handlers/<YourSite>.rs.
  2. Push the new handler to the inventory: inventory::submit! { &YourSiteHandler as &dyn SiteDefinition }
  3. Add the new module to handlers.rs.
  4. Optionally, add new requirements to Cargo.toml.
  5. Send me a patch, preferably with an example. (I cannot know all sites.)

Minimal example that does nothing

// handlers/noop.rs

use anyhow::Result;
use crate::definitions::SiteDefinition;

struct NoopExampleHandler;
impl SiteDefinition for NoopExampleHandler {
    fn can_handle_url<'a>(&'a self, url: &'a str) -> bool {
        // Return true here, if <url> can be covered by this handler.
        // Note that yaydl will skip all other handlers then.
        true
    }
    
    fn does_video_exist<'a>(&'a self, url: &'a str) -> Result<bool> {
    	// Return true here, if the video exists.
    	false
    }
    
    fn find_video_title<'a>(&'a self, url: &'a str) -> Result<String> {
        // Return the video title from <url> here.
        Ok("".to_string())
    }
    
    fn find_video_direct_url<'a>(&'a self, url: &'a str, onlyaudio: bool) -> Result<String> {
        // Return the direct download URL of the video (or its audio version) here.
        Ok("".to_string())
    }

    fn find_video_file_extension<'a>(&'a self, url: &'a str, onlyaudio: bool) -> Result<String> {
        // Return the designated file extension of the video (or audio) file here.
        Ok("mp4".to_string())
    }

    fn display_name<'a>(&'a self) -> String {
        // For cosmetics, this is the display name of this handler.
        "NoopExample"
    }
}
   
// Push the site definition to the list of known handlers:
inventory::submit! {
    &NoopExampleHandler as &dyn SiteDefinition
}

Fix some bugs or add new features

  1. Do so.
  2. Send me a patch.

Donations

Writing this software and keeping it available is eating some of the time which most people would spend with their friends. Naturally, I absolutely accept financial compensation.

Thank you.
