TwitchDownloader

Twitch VOD/Clip/Chat downloader and chat renderer I wrote.

THIS USES UNDOCUMENTED API ENDPOINTS, MAY BREAK EASILY. I'LL TRY AND UPDATE WHEN IT DOES.

Chat Render Example

What can it do?

Download Twitch VODs
Download Twitch Clips
Download chat for VODS and Clips, in either a JSON with all the information or a simple text file
Use a previously generated JSON chat file to render the chat with FFZ and BTTV support (including GIFS)

Things still to be done

Fix bugs that slipped by
More options for chat rendering

GUI

Video Demonstration

Linux? MacOS?

Sorry, the GUI version is only avaliable for Windows :(

CLI

The CLI is cross platform and performs the main functions of the program. It works on Windows and Linux, but has not been tested on MacOS.

Documentation here.

I've never really made a command line utility before so things may change in the future. If you're on Linux, make sure fontconfig and libfontconfig1 are installed (apt-get install fontconfig libfontconfig1).

For example, you could copy/paste this into a .bat file on Windows, to download a VOD, chat, and then render in a single go.

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

Linux – Getting started

Go to Releases and download the latest version for Linux.
Extract TwitchDownloaderCLI
Browse to where you extracted the file and give it executable rights in Terminal:

sudo chmod +x TwitchDownloaderCLI

You can now start using the donwloader, for example:

TwitchDownloaderCLI -m VideoDownload --id <vod-id-here> -o out.mp4

For Arch Linux, there's an AUR Package
