GUI

Windows WPF

See the full WPF documentation here.

Functionality

The Windows WPF GUI implements all of the main functions of the program along with some extra quality of life functions:

Queue up multiple download/render jobs to run simultaneously
Create a list of download jobs from a list of vod/clip links
Search for and download multiple VODs/clips from any streamer without leaving the app

Multi-language Support

The Windows WPF GUI is available in multiple languages thanks to community translations. See the Localization section of the WPF README for more details.

Theming

The Windows WPF GUI comes bundled with both light and dark themes, along with an option to update live according the current Windows theme. It also supports user created themes! See the Theming section of the WPF README for more details.

Linux?

Check twitch-downloader-gui on github or on the AUR for a Linux GUI wrapper for the CLI.

MacOS?

No GUI is available for MacOS yet :(

CLI

See the full CLI documentation here.

The CLI is cross-platform and implements the main functions of the program. It works on Windows, Linux, and MacOS^*.

^{*Only Intel Macs have been tested}

With the CLI, it is possible to automate video processing using external scripts. For example, you could copy-paste the following code into a .bat file on Windows to download a VOD and its chat, and then render the chat, all from a single input.

@echo off
set /p vodid="Enter VOD ID: "
TwitchDownloaderCLI.exe videodownload --id %vodid% --ffmpeg-path "ffmpeg.exe" -o %vodid%.mp4
TwitchDownloaderCLI.exe chatdownload --id %vodid% -o %vodid%_chat.json -E
TwitchDownloaderCLI.exe chatrender -i %vodid%_chat.json -h 1080 -w 422 --framerate 30 --update-rate 0 --font-size 18 -o %vodid%_chat.mp4

Windows - Getting started

Go to Releases and download the latest version for Windows or build from source.
Extract TwitchDownloaderCLI.exe.
Browse to where you extracted the file in the terminal.
If you do not have ffmpeg, you can install it via Chocolatey package manager, or you can get it as a standalone file from ffmpeg.org or by using TwitchDownloaderCLI:

TwitchDownloaderCLI.exe ffmpeg --download

You can now start using the downloader, for example:

TwitchDownloaderCLI.exe videodownload --id <vod-id-here> -o out.mp4

Linux – Getting started

Some distros, like Linux Alpine, lack fonts for some languages (Arabic, Persian, Thai, etc.) If this is the case for you, install additional fonts families such as Noto or check your distro's wiki page on fonts as it may have an install command for this specific scenario, such as the Linux Alpine font page.
Ensure both fontconfig and libfontconfig1 are installed. apt-get install fontconfig libfontconfig1 on Ubuntu.
Go to Releases and download the latest binary for Linux, grab the AUR Package for Arch Linux, or build from source.
Extract TwitchDownloaderCLI.
Browse to where you extracted the file and give it executable rights in the terminal:

sudo chmod +x TwitchDownloaderCLI

a) If you do not have ffmpeg, you should install it via your distro package manager, however you can also get it as a standalone file from ffmpeg.org or by using TwitchDownloaderCLI:

./TwitchDownloaderCLI ffmpeg --download

b) If downloaded as a standalone file, you must also give it executable rights with:

sudo chmod +x ffmpeg

You can now start using the downloader, for example:

./TwitchDownloaderCLI videodownload --id <vod-id-here> -o out.mp4

MacOS – Getting started

Go to Releases and download the latest binary for MacOS or build from source.
Extract TwitchDownloaderCLI.
Browse to where you extracted the file and give it executable rights in the terminal:

chmod +x TwitchDownloaderCLI

a) If you do not have ffmpeg, you can install it via Homebrew package manager, or you can get it as a standalone file from ffmpeg.org or by using TwitchDownloaderCLI:

./TwitchDownloaderCLI ffmpeg --download

b) If downloaded as a standalone file, you must also give it executable rights with:

chmod +x ffmpeg

You can now start using the downloader, for example:

./TwitchDownloaderCLI videodownload --id <vod-id-here> -o out.mp4
