# EZLive: Self-hosted Serverless Livestream
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](https://github.com/Haivision/srt)
- FFMpeg (libavformat, libavutil, libavcodec)
- AWS C++ SDK (libaws-cpp-sdk-core, libaws-cpp-sdk-s3)
Build:
make
# 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:
```
./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`.
# WARNING
The Docker build was done on my laptop. While I promise I have no malicious intent, this does not guarantee that my build environment is secure, so is the build target. If you truly care about your privacy and security, please make sure to build from source yourself.
# Docker Usage
Download the docker image tarball in [release](https://github.com/mistivia/ezlive/releases).
Load the docker image:
cat ezlive-docker-image.tar.gz | gzip -d | sudo docker load
Create a directory `conf`:
mkdir conf
Create a config file `conf/config`, the config file is nearly the same as the config above. But for docker, the `listening_addr` should be `0.0.0.0`:
listening_addr=0.0.0.0
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
Start docker container:
sudo docker run -it --rm \
-v ./conf:/etc/ezlive/ \
-p 127.0.0.1:61935:61935/udp \
localhost/ezlive
