ZeStream - An adaptive video streaming server

What is adaptive video streaming?

Ever wonder how Youtube/Netflix/Tiktok changes the resolution of the video, you are watching depending on your network speed?

You want to implement the similar feature in your own product, without any hassle?

ZeStream is the backend service which you can self-deploy, and use its API to process the video and store it on a storage bucket like AWS S3/Google Cloud/Azure....

Architecture

Implementation

1. User calls API to prcoess the video.
2. The API controller queues the event in a message queue (Kafka) and calls the given webhook.
3. A ZeStream worker polls the event from queue which contains file url
4. Worker fetches the file to local disk
5. Another worker starts a FFmpeg thread to process the video
6. Output is stored in local disk
7. After FFmpeg finishes processing, another worker pushes the files to cloud storage
8. CDN is connected to storage for fetching the files.

Dev Setup

1. Install Golang v1.19 from Go.dev
2. Fork this repo, and clone the forked repo
3. cd zestream-server
4. go get .
5. go run main.go
