yaydl

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

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 install

From the source code

Install Rust (e.g. with rustup), then:

using Fossil:

% fossil clone https://code.rosaelefanten.org/yaydl yaydl.fossil
% mkdir yaydl ; cd yaydl ; fossil open ../yaydl.fossil
% cargo build --release

using Git:

% git clone https://github.com/dertuxmalwieder/yaydl
% cd yaydl
% cargo build --release

From your package manager

Nobody has provided any packages for yaydl yet. You can help!

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

```rust // handlers/noop.rs

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

struct NoopExampleHandler; impl SiteDefinition for NoopExampleHandler { fn canhandleurl<'a>(&'a self, url: &'a str) -> bool { // Return true here, if 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.
