Nginx RTMP not recording - php

Question

I already setting up Nginx RTMP in ubuntu linux hosted by DigitalOcean. And currently running my laravel web application in localhost mode in my desktop. Everything seems work fine for the live streaming. I'm testing with my localhost JWPlayer and Open Broadcaster Software(OBS) for live streaming. It works. But whenever I need to record the streaming video to linux directory (/var/www), seems like nothing happen and no error at all after I hit stop streaming button in OBS.
I'm don't know how does the recording works, I try record manual and it has the link on it. I click start record, it comes out /var/rec/{mystream}.flv
This manual version of recording link embed in laravel website:
rtmp {
server {
listen 1935;
chunk_size 4096;
application live {
live on;
recorder rec1 {
record all manual;
record_suffix all.flv;
record_path /var/rec;
record_unique on;
}
}
}
}
Start Recording:
Start rec1
nginx config for http:
access_log logs/rtmp_access.log;
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
By the way
Plan B: I plan to store my recorded stream files to Amazon AWS s3. Anyone know how to do this with RTMP Nginx instead of using Wowza Amazon.

Answer 1

You can run inside shell script nginx conf. Check the permission first:
chown -R nobody:nogroup foldername
chmod -R 700 foldername
Shell script:
ffmpeg -v error -y -i "$1" -vcodec libx264 -acodec aac -f mp4 -movflags +faststart "/tmp/recordings/$2.mp4"
aws s3 cp "/tmp/recordings/$basname.mp4" "s3://bucketname/"
exec_record_done bash -c "/home/ubuntu/script/record.sh $path $basname";

Answer 2

You should check the permissions on the directory you're trying to record to (/var/rec in your case). Nginx, even though started up with sudo, spawns worker processes as user "nobody" by default. You can also try changing the user that the worker processes spawn as: https://serverfault.com/a/534512/102045

Answer 3

When i did this with my partner I would use
record_path /tmp/rec;
Then in the file I would set a crontab that permanently tries to send new files(videos) to his NextCloud FTP(In this case could be your amazon aws)

Answer 4

It seems like bhh1998 and akash jakhad answers are correct, although it seems that nowadays the nginx.conf file comes with nginx user as default, so instead of using nobody and nogroup, use only nginx instead. The command mentioned in previous answers would be like this:
chown -R nginx:nginx foldername
To be sure of the correct username, check your configuration file and see which user is being specified.

Answer 5

In addition to the user permission settings mentioned in other answers, I also had to change the path to end with a trailing slash i.e. /var/rec/ instead of /var/rec.
