Discord self-bot video

Fork: Discord-video-experiment

Caution

Using any kind of automation programs on your account can result in your account getting permanently banned by Discord. Use at your own risk

Features

• Playing video & audio in a voice channel (Go Live, or webcam video)

Implementation

What I implemented and what I did not.

Video codecs

• VP8 (once supported, removed for maintainability)
• VP9
• H.264
• H.265
• AV1

Packet types

• RTP (sending of realtime data)
• RTX (retransmission)

Connection types

• Regular Voice Connection
• Go Live

Encryption

• Transport Encryption
• End-to-end Encryption

Extras

• Figure out RTP header extensions (discord specific) (discord seems to use one-byte RTP header extension)

Extensions supported by Discord (taken from the webrtc sdp exchange)

Requirements

For full functionality, this library requires an FFmpeg build with libzmq enabled. Here is our recommendation:

• Windows & Linux: BtbN's FFmpeg Builds
• macOS (Intel): evermeet.cx
• macOS (Apple Silicon): Install from Homebrew

Usage

Install the package, alongside its peer-dependency discord.js-selfbot-v13:

npm install @dank074/discord-video-stream@latest
npm install discord.js-selfbot-v13@latest

Important

If you're using pnpm, you need to run pnpm approve-builds and approve node-datachannel, or else native dependencies will be missing and you'll get import errors

Create a new Streamer, and pass it a selfbot Client

import { Client } from "discord.js-selfbot-v13";
import { Streamer } from '@dank074/discord-video-stream';

const streamer = new Streamer(new Client());
await streamer.client.login('TOKEN HERE');

Make client join a voice channel

await streamer.joinVoice("GUILD ID HERE", "CHANNEL ID HERE");

Start sending media

import { prepareStream, playStream, Utils, Encoders } from "@dank074/discord-video-stream"
try {
    // NVENC is also available, change Encoders.software to Encoders.nvenc and
    // adapt the settings
    let encoder = Encoders.software({
        x264: {
            preset: "superfast"
        },
        x265: {
            preset: "superfast"
        }
    });
    const { command, output } = prepareStream("DIRECT VIDEO URL OR READABLE STREAM HERE", {
        encoder,

        // Specify either width or height for aspect ratio aware scaling
        // Specify both for stretched output
        height: 1080,

        // Force frame rate, or leave blank to use source frame rate
        frameRate: 30,
        bitrateVideo: 5000,
        bitrateVideoMax: 7500,
        videoCodec: Utils.normalizeVideoCodec("H264" /* or H265 */),
    });
    command.on("error", (err, stdout, stderr) => {
        // Handle ffmpeg errors here
    });

    await playStream(output, streamer, {
        type: "go-live" // use "camera" for camera stream
    });

    console.log("Finished playing video");
} catch (e) {
    console.log(e);
}

Performance tips

See this page for some tips on improving performance

Running example

examples/basic/src/config.json:

"token": "SELF TOKEN HERE",
"acceptedAuthors": ["USER_ID_HERE"],

1. Configure your config.json with your accepted authors ids, and your self token
2. Generate js files with npm run build
3. Start program with: npm run start
4. Join a voice channel
5. Start streaming with commands:

for go-live

$play-live <Direct video link>

or for cam

$play-cam <Direct video link>

for example:

$play-live http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4

FAQs

• Can I stream on existing voice connection (CAM) and in a go-live connection simultaneously?

Yes, just send the media packets over both connections. The voice gateway expects you to signal when a user turns on their camera, so make sure you signal using client.signalVideo(guildId, channelId, true) before you start sending cam media packets.

• Does this library work with bot tokens?

No, Discord blocks video from bots which is why this library uses a selfbot library as peer dependency. You must use a user token
