# Video server

### Generating certificates

##### To generate SSL certificates you must:
1. Go to `/server/ssl`
2. Execute `openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem`

### Development

##### To start in development mode you must:
1. Install the dependencies `npm install`.

2. Go to the linx-devops project and run the `create_certificate_for_domain.sh` script from `private-system-trusted-cert`, it expects an ip/domain as the first argument.
   ex: `sh create_certificate_for_domain.sh 192.168.1.199`
   (Use your private IP-address)

3. You need to update the Video Server in the provisioning to point to your private IP. ex: https://192.168.1.199:3000

4. The generated files must be moved to server/ssl and renamed as follows:
- device.key -> key.pem
- nginx-selfsigned.crt -> cert.pem

5. Go to https://dev.linx.safemobile.com/dispatcher/resources/help/LINXHelp.html#safemobile-certificate-import and import the certificate for your system type

6. The ANNOUNCED IP in .env must be configured to use the same private IP used in generating the certificate.

7. Run the `npm start:dev` command to start the server in dev mode.
   (Any change will trigger a refresh of the server)

### Production

##### To start in production mode you must:
1. Install the dependencies `npm install`.
2. Run the `npm start:prod` command to start the server in production mode.
(To connect to the terminal, use `pm2 log video-server`)


### Web client

- The server will start by default on port 3000, and the ssl certificates will have to be configured
- The web client can be accessed using the /sfu path
ex: https://HOST/sfu/?assetId=1&&accountId=1&producer=true&dest_asset_id=75&assetName=Adi
assetId = asset id of the unit on which you are doing the test
accountId = account id of the unit on which you are doing the test
producer = it will always be true because you are the producer
(it's possible to put false, but then you have to have another client with producer true)
assetName = asset name of the unit on which you are doing the test
dest_asset_id= the addressee with whom the call is made
- To make a call using this client, you need a microphone and permission to use it
- For any changes related to the client, the command `npm run watch' will have to be used to generate the bundle.js used by the web client
