Nginx Live Stream Configuration

ZgreG · June 14, 2017, 2:45pm

Hello,

I install lastest Kaltura CE 12.17 on a CentOs-7.
Everything is working well exept the Nginx Live Stream mod.
I follow instructions of this post :

github.com

kaltura/platform-install-packages/blob/Lynx-12.17.0/doc/nginx-rtmp-live-streaming.md

# Live Streaming with Nginx and the RTMP module
Kaltura CE includes the kaltura-nginx package, which is compiled with the [Nginx RTMP module](https://github.com/arut/nginx-rtmp-module).

## Nginx RTMP Configuration
The paths to the configuration files for kaltura-nginx vary depending on rather you use the Deb or the RPM package.

For deb, the main file is here:
```
/opt/kaltura/nginx/conf/nginx.conf
```
For RHEL:
```
/etc/nginx/nginx.conf
```

```
rtmp {
    server {
      listen 1935; # Listen on standard RTMP port
      chunk_size 4000;

This file has been truncated. show original

Using Wirecast to send video on my server, the connection is ok but nothing happens on HTML5 Video Player even on the folder /var/tmp/hlsme/
I haven’t any server side error message.
Someone can help me to search where the problem could be ?

Thanks,
GreG

Hello @ZgreG,

I’ve never used Wirecast myself but if it can stream over RTMP, it should work.
As a starting point, I suggest you try with the ffmpeg command in the howto and see if files are created under /var/tmp/hlsme and whether errors are thrown to SRDOUT/STDERR, and also have a look at the Nginx error log.

Hello @jess,

Thanks for your reply.
I used the FFMPEG command and here are the results :

on local server : Connection to tcp://xxxx.fr:1935 failed (Connection refused), trying next address
on remote workstation : The stream is going right but when I stop it two error messages

> [flv @ 0x7fbf78817000] Failed to update header with correct duration.107.7kbits/s speed=   1x     
> [flv @ 0x7fbf78817000] Failed to update header with correct filesize.

In the two cases, nothing happens in the directory /var/tmp/hlsme.
I don’t have any Nginx error.
(Can you explain to me quickly what is SRDOUT/STDERR ?)

In the folder /var/tmp/, I created the forders hlsme with kaltura.apache owner.
I see that I have many strange folders :

drwxr-xr-x 2 kaltura apache 4096 Jun 16 11:38 hlsme
drwx------ 3 root    root   4096 Jun 14 12:58 systemd-private-2102f54c325d4cc9abd21af192b238b3-dovecot.service-gidGuK

It’s possible to be an autorisation problem ?

Thank you,
GreG

Hi @ZgreG,

Nothing can happen until your client is able to communicate with Nginx [running the RTMP module] over port 1935 TCP. From your output, it looks like it fails to do so.
On the server run:
# netstat -plnt|grep nginx
make sure Nginx does indeed listen on port 1935 [RTMP default]. If you selected a different port for RTMP during the configuration phase then of course, you need to change the ffmpeg command on the client side accordingly.

Assuming everything looks OK on the server side, from the client run:
# telnet $NGNIX_HOST 1935

Make sure you arrive at a prompt, like so:

Connected to $NGNIX_HOST.
Escape character is '^]'.

if you do not, then you must have FW rules that are blocking the communication and you should adjust them so your client is able to reach the Nginx server over the RTMP port.

ZgreG · June 16, 2017, 11:20am

@jess

On server side :
# netstat -plnt|grep nginx

tcp 0 0 0.0.0.0:1935 0.0.0.0:* LISTEN 899/nginx: master p
tcp 0 0 0.0.0.0:88 0.0.0.0:* LISTEN 899/nginx: master p

On client side :
# telnet $NGNIX_HOST 1935

Trying x.x.x.x...
Connected to $NGNIX_HOST.
Escape character is '^]'.

Everything seems ok about communication …
No ?

@jess

Can you explain me quickly what do mean :

If it can help me to resolve my problem …
Many thanks,
GreG

jess · June 16, 2017, 3:59pm

When outputting to the screen, there is STDOUT [Standard Output stream] and STDERR [Standard Error stream].
All I meant is you should look for errors outputted to your screen when running all mentioned commands.

Please paste the full ffmpeg command you used when trying to stream and all the output you got.

ZgreG · June 16, 2017, 4:20pm

@jess

Ok, thanks

Here the full ffmpeg command :

$ ffmpeg -re -i /Users/Greg/Documents/www-dev/Kimsufi-GreG/Sources/PAP-test/tests/PAP-test.mp4 -c copy -f flv “rtmp://vodyou.fr:1935/kLive/Test”

jess · June 16, 2017, 4:28pm

@ZgreG,

Your command and output seem fine.
Although I am very confused about this:

Why does it work correctly from the outside and not from the server itself? does the server have a different IP for this hostname in /etc/hosts or something?

At any rate, while streaming, you’re suppose to see files added to
/var/tmp/hlsme:

Test-0.ts
Test.m3u8

and so on…
If you do not, what permissions are set on the /var/tmp/hlsme dir?
Also, what’s in the logs under /opt/kaltura/log/nginx?

jess · June 16, 2017, 4:29pm

It shouldn’t include ‘.m3u8’.
Your previous command was fine. See my last reply,
Also, you seem to alternate between upper and lower case, please make sure to be consistent. On a UNIX FS ‘TesT’, ‘test’ and ‘Test’ are not the same thing.

ZgreG · June 16, 2017, 4:44pm

@jess

Ok, some news …
On the server, I try this command :

ffmpeg -re -i /var/local/PAP-test.mp4 -c copy -f flv “rtmp://5.135.188.49:1935/kLive/test”

The encoding process good without any error message :

Edit /etc/nginx/nginx.conf so that:

error_log  /opt/kaltura/log/kaltura_nginx_errors.log;

becomes:

error_log  /opt/kaltura/log/kaltura_nginx_errors.log debug;

Then restart the Nginx daemon with:
# service kaltura-nginx restart
Try to stream again and look at what’s outputted to /opt/kaltura/log/kaltura_nginx_errors.log

Ok I’ve some results now in kaltura_nginx_errors.log

And yet, you’re saying that WHILE STREAMING there is nothing under /var/tmp/hlsme/? After the ffmpeg command is done the files will be cleared so I want to make sure you are checking this while actively streaming and not afterwards.

ZgreG · June 16, 2017, 5:35pm

@jess
Yes I’ve just checked with my client stream.

jess · June 16, 2017, 5:37pm

I’m not sure what you mean by “I checked with client stream”…
What I want you to do is run the ffmpeg command and then SSH to the server and run:
# ls -al /var/tmp/hlsme

ZgreG · June 16, 2017, 5:42pm

I launch the stream with my client and checked on the server folder.

So I found the files …
They are in :

/var/tmp/systemd-private-#KEY#-kaltura-nginx.service-WH2Hue/tmp/hlsme

And I confirm that at the end, the files are deleted.

jess · June 16, 2017, 5:44pm

I don’t understand what /var/tmp/systemd-private-#KEY#-kaltura-nginx.service-WH2Hue/tmp/hlsme is…
The Nginx config has:

hls_path /var/tmp/hlsme/;

in /etc/nginx/nginx.conf
When streaming, do you or do you not see the m3u8 and the ts files there?
Did you change the configuration to place the files in a different path? if so, why? if not, what’s under /var/tmp/hlsme when you stream?

ZgreG · June 16, 2017, 5:48pm

No, I didn’t change the path in nginx.conf

# RTMP configuration
rtmp {
    server {
	listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        # This application is to accept incoming stream
        application kLive {
                live on; # Allows live input from above
                dash on;
                dash_path /var/tmp/dashme;

                hls on; # Enable HTTP Live Streaming
                hls_cleanup on;
                hls_sync 100ms;
                hls_fragment 2s;

                hls_path /var/tmp/hlsme/;


        }
    }
}

I see the m3u8 file and all TS files, during streaming, in the folder :
/var/tmp/systemd-private-#KEY#-kaltura-nginx.service-WH2Hue/tmp/hlsme

I don’t know why !!!
