In this tutorial we will serve video stored in Jetstream’s object store (like Amazon S3) as HTTP live streaming to a user’ browser. This makes it difficult for the user to save the whole video as it is served in chunks.
Load a test video on object store
Login to Horizon
Go to Project > Object store
Create a container, for example
videostream, make it public
Upload a test video, for example:
Wait 5 minutes then test you can access the video from your machine and note the base url.
Deploy the VM
Login to Atmosphere and launch the newest Ubuntu 20.04 image
The streaming server will ask for the SSL certificates on setup.
So, install certbot with:
sudo apt install certbot
and get certificates:
certbot certonly --standalone -d js-xxx-yyy.jetstream-cloud.org
Install the streaming server
Kaltura maintains packages for Ubuntu, so it is easy to install it following https://github.com/kaltura/nginx-vod-module#debianubuntu-deb-package
For the configuration interactive prompts (I might have set them out of order here):
- Use port 80 instead of 88 (unless you plan to have another NGINX instance on port 80)
- Use port 443 instead of 8443
- For the mode choose “Remote”, we will load from object store
- For the remote url set the base url of the object store (before
/swift) and the port
- Say “No” when it asks if you use the Kaltura media service
- For SSL certificate set
- For SSL key set
By default it sets the streaming from HTTP instead of HTTPS,
If anything goes wrong in the configuration, check the error log at:
and reset it:
sudo apt purge kaltura-nginx rm -fr /opt/kaltura sudo apt install kaltura-nginx
Test the streaming
First try to access the stream directly from your browser, browsers don’t know how to display a HLS stream, but if you get to download a file named “index.m3u8” that is a good sign:
In the URL,
videostream is the name of the bucket (container), then the filename,
index.m3u8 tells the server
that we want to stream that into HLS format.
If you get an error message instead, check the Kaltura NGINX logs.
Finally we can test it into a player, for example VideoJS, go to https://videojs-http-streaming.netlify.app/ and paste the URL of your stream.
