This project is a tool to automatically create compilation videos from Twitch clips for a specific game. It consists of a Golang backend that queries the Twitch API to find recent clips for a game, and the FFMPEG go package for video editing scripts that filters the clips and stitches together clips into a full video.
This project served as an opportunity to learn more about Golang development coming from a JavaScript background. I wanted to understand the differences in language syntax, built-in libraries, concurrency models, and overall structure of Golang apps.
My original Node.js application relied on the YouTube API and Remotion for video editing, which introduced more complexity than needed. By switching to FFMPEG in Golang, I was able to simplify the video processing portion dramatically.
Golang's goroutines and channels provide built-in concurrency primitives that enable efficient parallelism. This project gave me hands-on experience using these tools to speed up tasks like fetching clips concurrently from the Twitch API.
- Fetch recent clips for a game from Twitch API.
- Download clips locally.
- Add video filter with the broadcaster name in it.
- Compile and stitch clips into a full video.
- Output video in mp4 format.
- Golang (fmt, io, net/http, os, sync, time, encoding/json)
- FFMPEG-GO package (github.com/u2takey/ffmpeg-go)
- Twitch API (Token Auth and Helix Games)
I run the commmand:
go run ./src/Input the Parameters
Game name: Fortnite
Clip size: 20
Days before: 7Then the clips will start to download locally:
