GitHub - mistivia/ezlive: self-hosted serverless livestream using s3

EZLive is a minimal self-hosted livestream solution built on top of S3-compatible object storage.

It runs a local SRT server, receive live video, turns it into HLS segments (.m3u8 + .ts) and serves them as static files through any S3-compatible object storage. No dedicated streaming server is required — everything runs serverlessly. Then you can easily setup a HTML5 HLS player to watch the stream.

Build

Install dependencies:

• SRT
• FFMpeg (libavformat, libavutil, libavcodec)
• AWS C++ SDK (libaws-cpp-sdk-core, libaws-cpp-sdk-s3)

Build:

Usage

Setup a S3-compatible object storage bucket, for example, Cloudflare R2, AWS S3, Minio, DigitalOcean, etc.

Then create a config file config:

listening_addr=127.0.0.1
listening_port=61935
bucket=YOUR_BUCKET_NAME
endpoint=https://your-s3.com
s3_path=ezlive/
access_key=YOUR_S3_ACCESS_KEY
secret_key=YOUR_S3_SECRET_KEY
region=auto
key=your_live_key

In the dashboard of your object storage provider, enable public read, and add the domain name of your web HLS player to CORS setting. If you don't know how to setup a web HLS player, just add https://mistivia.github.io.

For AWS S3, Edit bucket setting, set "Permissions" -> "Bucket Policy" to:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicReadOnly",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::YOUR_BUCKET/*"
        }
    ]
}

Then set "Permissions" -> "Cross-origin resource sharing (CORS)" to:

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "GET"
        ],
        "AllowedOrigins": [
            "https://your.hls.player.com"
        ],
        "ExposeHeaders": []
    }
]

Start EZLive:

Open OBS, streaming to srt://127.0.0.1:61935, with streaming key. The streaming format must be H.264 + AAC.

Then use a HLS player to load https://YOUR_BUCKET_NAME.your-s3.com/ezlive/stream.m3u8 to watch the stream.

If you don't know how to setup a HLS player, then make sure you have added https://mistivia.github.io in your object storage's CORS setting, then open https://mistivia.github.io/ezlive#https://YOUR_BUCKET_NAME.your-s3.com/ezlive/stream.m3u8.
