Data Privacy in Business : A Risk Leading to Major Opportunities

How can I improve the up-time of my coffee pot live stream ?
26 avril 2017, par tww0003Some Background on the Project :
Like most software developers I depend on coffee to keep me running, and so do my coworkers. I had an old iPhone sitting around, so I decided to pay homage to the first webcam and live stream my office coffee pot.
The stream has become popular within my company, so I want to make sure it will stay online with as little effort possible on my part. As of right now, it will occasionally go down, and I have to manually get it up and running again.
My Setup :
I have nginx set up on a digital ocean server (my nginx.conf is shown below), and downloaded an rtmp streaming app for my iPhone.
The phone is set to stream to
example.com/live/stream
and then I use an ffmpeg command to take that stream, strip the audio (the live stream is public and I don’t want coworkers to feel like they have to be careful about what they say), and then make it accessible atrtmp://example.com/live/coffee
andexample.com/hls/coffee.m3u8
.Since I’m not too familiar with ffmpeg, I had to google around and find the appropriate command to strip the coffee stream of the audio and I found this :
ffmpeg -i rtmp://localhost/live/stream -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv -an rtmp://localhost/live/coffee
Essentially all I know about this command is that the input stream comes from,
localhost/live/stream
, it strips the audio with-an
, and then it outputs tortmp://localhost/live/coffee
.I would assume that
ffmpeg -i rtmp://localhost/live/stream -an rtmp://localhost/live/coffee
would have the same effect, but the page I found the command on was dealing with ffmpeg, and nginx, so I figured the extra parameters were useful.What I’ve noticed with this command is that it will error out, taking the live stream down. I wrote a small bash script to rerun the command when it stops, but I don’t think this is the best solution.
Here is the bash script :
while true;
do
ffmpeg -i rtmp://localhost/live/stream -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv -an rtmp://localhost/live/coffee
echo 'Something went wrong. Retrying...'
sleep 1
doneI’m curious about 2 things :
- What is the best way to strip audio from an rtmp stream ?
- What is the proper configuration for nginx to ensure that my rtmp stream will stay up for as long as possible ?
Since I have close to 0 experience with nginx, ffmpeg, and rtmp streaming any help, or tips would be appreciated.
Here is my nginx.conf file :
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
allow 127.0.0.1;
}
location /stat.xsl {
root html;
}
location /hls {
root /tmp;
add_header Cache-Control no-cache;
}
location /dash {
root /tmp;
add_header Cache-Control no-cache;
add_header Access-Control-Allow-Origin *;
}
}
}
rtmp {
server {
listen 1935;
chunk_size 4000;
application live {
live on;
hls on;
hls_path /tmp/hls;
dash on;
dash_path /tmp/dash;
}
}
