rustube

A complete (WIP), and easy to use YouTube downloader.

Note: 0.3.5 is a temporary fix to adapt to changes in the YouTube api (#38). Unfortunately this fix does not work for age restricted videos. We are working on a fix for that in #39.

Roadmap

• download normal videos
• download age restricted videos (no longer works since 0.3.5 due to a change in the YouTube API)
• asynchronous API
• blocking API
• full video info deserialization
• feature based opt-in deserialization of video info
• CLI
• testing suite
• benchmarks
• Python bindings
• C / C++ bindings

Usage

rustube provides an extremely easy to use API. If you just want to download a video and don't care about any intermediate steps and any video information, this is all you need:

#[tokio::main]
async fn main() {
    let url = "https://www.youtube.com/watch?v=Edx9D2yaOGs&ab_channel=CollegeHumor";
    println!("downloaded video to {:?}", rustube::download_best_quality(&url).await.unwrap());
}

Of course, rustube has a lot more capabilities than just downloading videos. It also aims at deserializing the complete video information provided by YouTube (this is still WIP). So finding out the view count of a video is as simple as:

use rustube::{Id, VideoFetcher};

let id = Id::from_raw("https://www.youtube.com/watch?v=Edx9D2yaOGs&ab_channel=CollegeHumor").unwrap();
let descrambler = VideoFetcher::from_id(id.into_owned())
        .unwrap()
        .fetch()
        .await
        .unwrap();

let view_count = descrambler.video_details().view_count;
let title = descrambler.video_title();
println!("The video `{}` was viewed {} times.", title, view_count);

For more examples, an overview of the blocking API have a look at the API documentation.

CLI

rustube comes with a CLI, rustube-cli, so you can download your favorite YouTube videos without having to write a single line of code.

To install it, simply run

cargo install rustube-cli

After you successfully installed rustube-cli, you have access to the command rustube

A simple CLI for the rustube YouTube-downloader library.
For documentation and more information about rustube or the rustube-cli checkout
`https://github.com/DzenanJupic/rustube`.

For help with certain subcommands run `rustube <SUBCOMMAND> --help`.

USAGE:
    rustube <SUBCOMMAND>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    check       Checks if a video can be downloaded and fetches information about it
                This command is similar to fetch, in the way that it also fetches information
                about a video, but, other then fetch, will also decrypt all stream URLs.
                Therefore you can use the returned URLs for downloading the video. This of
                course means that the video has to be downloadable.
                By default this command will check for any streams that contain a video and an
                audio track. To specify other behavior, like checking for a stream with a
                particular quality, have a look at the subcommand help.
    download    Downloads a YouTube video
                By default, the Stream with the best quality and both a video, and an audio
                track will be downloaded. To specify other download behavior, have a look the
                the subcommand help.
    fetch       Fetches information about a YouTube video
                Fetching information does not require the video to actually be downloadable. So
                this also works when a video is, i.e., an offline stream. The downside is that
                you often don't have access to the stream URLs. Some videos come with pre-
                decrypted urls, in which case you can also use these to download the video, but
                if the video url is encrypted there's no way for you to download the video using
                only the returned information. To get decrypted URLs, have a look at `check`.
                For most use cases it's recommended to use `check` instead, since it gives you
                both more control and more information.
    help        Prints this message or the help of the given subcommand(s)
