broadway_stream_example's Introduction

broadway_stream_example

Simple example to test Broadway with a video stream from ffmpeg

Why

I struggled many days before having a working h264 video stream working with Broadway. It is not necessary that another one loose more time doing the same thing, It is why I decieded to share my tests. The main difficulty comes from how to genrate and give the stream to Broadway.js.

How

The example's input is the PC's webcam. FFmpeg capturs the webcam's stream and forward it as a H264 stream to an HTTP server. The HTTP server put he stream in a websocket to feed the Broadway player. It works fo Chrome nd Firefox.

server <--http(8080)-- browser
and
ffmpeg --http(8081)--> relay <--websocket(8082)--> browser + broadway

There is also a version without websocket. It obviously works wores than the websocket version.

Installation

git clone https://github.com/olivier-montagner/broadway_stream_example.git`

npm install

ffmpeg is also needed. FFmpeg

Launch

In your console:

node wsrelay.js

In your browser:

http://localhost:8080/view-broadway.html

In another console (for windows):

ffmpeg -f dshow -i video="Integrated Webcam" -framerate 25 -video_size 640x480 -pix_fmt yuv420p -c:v libx264 -b:v 2000k -bufsize 1000k -vprofile baseline -tune zerolatency -f rawvideo http://localhost:8081`

video="Integrated Webcam" may depend on your hardware.
