Kaltura-CE 16.14 CentOS 7 no Live Stream

guillem_liarte · January 21, 2021, 4:13pm

I have an apparently working Kaltura CE installation. Uploading and playing videos works perfectly. Howeve, live streaming is not working as intended.

My system:

cat /etc/redhat-release

I have SELinux on permissive
There are firewalls but all ports are open and services enabled.

I have the default config shipped in /etc/nginx/nginx.conf

I followed different instructions to make create a stream and it seems happen correctly.
If follow this example:

github.com

kaltura/platform-install-packages/blob/Propus-16.15.0/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

I can create the stream entry perfectly and, aside from getting any content, everything else is there.

I get a Stream URL such as:

http://kaltura.xxxxxx.com/hlsme/test.m3u8

I can send a video like this:

ffmpeg -re -i Downloads/video.mp4 -c:v copy -c copy -f flv "http://kaltura.xxxxxx.com/hlsme/test.m3u8"

in the API log i see:

In KMC I can get to the preview:

http://kaltura.xxxxxx.com/index.php/extwidget/preview/partner_id/107/uiconf_id/23448178/entry_id/0_ml70up99/embed/auto?

However, this shows only:

" Currently not broadcasting, video will play once broadcasting starts "

I am at loss, as I do not see any obvious error.

I tried using "Kaltura Live Streaming " instead of Manual Live Stream URLs but with very similar effect.

I tried with both ffmpeg and OBS studio, with equal negative results.

Can someone help me troubleshoot this? Many thanks in advance.

We also followed this but with the same result:

The nginx is working correctly:

Hello @guillem_liarte

This is incorrect. The streaming needs to be done over RTMP, the content serving (using HLS) is done over HTTP[s]. See https://github.com/kaltura/platform-install-packages/blob/Propus-16.15.0/doc/nginx-rtmp-live-streaming.md#streaming

And the live entry type should be Manual Live Stream URLs, see https://github.com/kaltura/platform-install-packages/blob/Propus-16.15.0/doc/nginx-rtmp-live-streaming.md#creating-a-live-stream-entry

Cheers,

guillem_liarte · January 22, 2021, 1:48pm

Hello @jess thanks for the reply.

Yes, I tried something like this:
My Manual Live stream looks like this:

http://kaltura.xxxxxx.com/:88/hlsme/test.m3u8

And i try to feed it with that:

ffmpeg -re -i Downloads/video.mp4 -c copy -f flv "rtmp://kaltura.xxxxx.com/kLive/test"

I get the entries looking like this:

So everything seems to be in place, but no show

And yes the ffmpeg does not give error:

ffmpeg -re -i Downloads/video.mp4 -c copy -f flv "rtmp://kaltura.xxxxx.com/kLive/test"

Hello,

Should be:
http://kaltura.xxxxxx.com:88/hlsme/test.m3u8

guillem_liarte · January 22, 2021, 4:02pm

Correct. Apologies for the typo.

guillem_liarte · January 22, 2021, 6:54pm

So, Manual live entries work.

Thank you.

I understand that Kaltura Live is not OK to use in Kaltura CE? Only Manual streams are contemplated, correct?

jess · January 29, 2021, 9:10am

Hello @guillem_liarte,

That’s correct, for CE, you should always use “Manual Live Stream” entries.

guillem_liarte · January 29, 2021, 9:25am

Thanks you @jess most appreciated.

Let’s imagine we upgrade our CE installation to self hosted, but with comercial/support license. Would that feature become live then?

This is a very likely scenario. How would we proceed?

jess · January 29, 2021, 9:55am

Hello @guillem_liarte,

Please contact our sales team and they’ll be glad to explain the various offerings.

Cheers,
