|
*Boooo!* A simple streaming server with authentication and open-source technologies.
|
|
|
|
This project was developped at [Cr@ns](https://crans.org/) to stream events.
|
|
|
|
Features:
|
|
|
|
- WebRTC playback with a lightweight web interface.
|
|
- SRT stream input, supported by FFMpeg, OBS and Gstreamer.
|
|
- Low-latency streaming, sub-second with web player.
|
|
- Authentification of incoming stream using LDAP server.
|
|
|
|
## Installation on Debian/Ubuntu
|
|
|
|
You need at least libsrt 1.4.1. On Ubuntu 20.04 or Debian Buster, you may manually install [libsrt1-openssl](http://ftp.fr.debian.org/debian/pool/main/s/srt/libsrt1-openssl_1.4.1-5+b1_amd64.deb) then [libsrt-openssl-dev](http://ftp.fr.debian.org/debian/pool/main/s/srt/libsrt-openssl-dev_1.4.1-5+b1_amd64.deb).
|
|
|
|
You may clone this repository, then `go run main.go` for debugging, or `go get gitlab.crans.org/nounous/ghostream`.
|
|
|
|
## Installation with Docker
|
|
|
|
An example is given in [docs/docker-compose.yml](docs/docker-compose.yml).
|
|
It uses Traefik reverse proxy.
|
|
|
|
You can also launch the Docker image using,
|
|
|
|
```
|
|
docker build . -t ghostream
|
|
docker run -it --rm -p 2112:2112 -p 9710:9710/udp -p 8080:8080 -p 10000-10005:10000-10005/udp ghostream
|
|
```
|
|
|
|
## Streaming
|
|
|
|
As stated by OBS wiki, when streaming you should adapt the latency to `2.5 * (the round-trip time with server, in μs)`.
|
|
|
|
### With OBS
|
|
|
|
As OBS uses FFMpeg, you need to have FFMpeg compiled with SRT support. To check if SR is available, run `ffmpeg -protocols | grep srt`.
|
|
On Windows and MacOS, OBS comes with his own FFMpeg that will work.
|
|
|
|
In OBS, go to "Settings" -> "Stream" and change "Service" to "Custom..." and "Server" to `srt://127.0.0.1:9710`.
|
|
|
|
### With GStreamer
|
|
|
|
To stream X11 screen,
|
|
|
|
```bash
|
|
gst-launch-1.0 ximagesrc startx=0 show-pointer=true use-damage=0 \
|
|
! videoconvert \
|
|
! x264enc bitrate=32000 tune=zerolatency speed-preset=veryfast byte-stream=true threads=1 key-int-max=15 intra-refresh=true ! video/x-h264, profile=baseline, framerate=30/1 \
|
|
! mpegtsmux \
|
|
! srtserversink uri=srt://127.0.0.1:9710/ latency=1000000
|
|
```
