RTMP / RTSP / HLS Streaming video

UPDATE: 20220906 – Started testing with steaming VR/360 also

RTMP stands for Realtime Messaging Protocol
RTSP stands for Realtime Streaming Protocol
HLS is a HTTP Live Streaming method

I needed a way to stream semi-realtime video to a website.
There are multiple use cases.

  • Streaming a boardgame online
  • Showing my desktop, while i was working on projects.
  • Watched (streamed) Curse of Oak Island with some friends while being in a Jitsi meeting at the same time together.

In all cases i used OBS to stream to the website.

Prepare the stream server:

Install nginx, with the rtmp module

wget http://nginx.org/download/nginx-1.9.7.tar.gz
wget https://github.com/arut/nginx-rtmp-module/archive/master.zip
tar -xvf nginx-1.9.7.tar.gz
unzip master.zip
cd nginx-1.9.7
./configure --add-module=../nginx-rtmp-module-master/
make && make install
mkdir -p /HLS/live/test # live is the stream name, test is the pass key
chown -R {nginx user} /HLS

create a config file

worker_processes  1;
error_log  logs/error.log debug;
events {
worker_connections  1024;
}
rtmp {
server {
listen 1935;
allow play all;

application live {
allow play all;
live on;
record all;
record_path /video_recordings;
record_unique on;
hls on;
hls_nested on;
hls_path /HLS/live;
hls_fragment 10s;

}

application vod {
play /video_recordings;
}

http {
include       mime.types;
default_type  application/octet-stream;

server {
listen 80;
server_name www.fash.nu;
add_header Access-Control-Allow-Origin *;

location /live {
types {
application/vnd.apple.mpegurl m3u8;
}
alias /HLS/live;
add_header Cache-Control no-cache;
}

location /mobile {
types {
application/vnd.apple.mpegurl m3u8;
}
alias /HLS/mobile;
add_header Cache-Control no-cache;
}

location / {
root   html;
index  index.html index.htm;
}
}

You need a webpage containing the embedded player

<!-- HTML -->
<video id='hls-example'  class="video-js vjs-default-skin" width="400" height="300" controls>
<source type="application/x-mpegURL" src="http://www.fash.nu:8080/live/test/index.m3u8">
</video>


<!-- JS code -->
<!-- If you'd like to support IE8 (for Video.js versions prior to v7) -->
<script src="https://vjs.zencdn.net/ie8/ie8-version/videojs-ie8.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/videojs-contrib-hls/5.14.1/videojs-contrib-hls.js"></script>
<script src="https://vjs.zencdn.net/7.2.3/video.js"></script>

<script>
var player = videojs('hls-example');
player.play();
</script>

Run the server part:

/usr/local/nginx/sbin/nginx -c /root/stream.conf

Now you can connect OBS to the streaming server

Open the webpage and enjoy!

2nd webcam showed card details. Also text boxes appeared who’s turn it was.

When attending the MCH2022 talk about streaming 360 video, i made a mental note to try this with my Vuze cam, using current setup and the one suggested in the talk : https://www.youtube.com/watch?v=460vo1O5pC4

Uboot Game

2019-06-08 I’ve bought myself Uboot the game.

It is one of my favourite board games.

Playing with a cardboard uboot is … okay. But when you have a 3D printer .. do i need to say more?

Parts printed

3D printed version assembled and completed in Jan 2021

All assembled and put Leds inside.

Led’s are controlled by a Arduino, Mqtt or a fysical button can be used.

Made a Crokinole game

Crokinole is played on a circular wooden board, with wooden circular disks as playing pieces.

Possible origin is Canada.

Players take turns shooting disks across the circular wooden board by flicking the disks with their fingers. Players try to land their disks in scoring regions on the board, with the highest scoring area the recessed hole in the very center of the board. Each round, each player/side alternately shoots a set number of disks (usually 12 or 8), shooting one disk each turn.

Players must position their disk on the start of each of their turns in their quadrant in front of them, touching the outer scoring ring boundary.

If there are no opponent’s disks on the board, they must aim for the center of the board.

If there is an opponent’s disk on the board, they must aim and hit an opponent’s piece first, either directly, or by a carrom shot.

The center recessed hole is worth 20 points, and disks are removed and scored at the end of the round if they land in the center hole.

Disks that are outside the outer scoring ring at the end of each shot, or are touching the outer scoring ring at the end of each shot, are removed from play for the round.
