The Jitsi Web and JVB containers now (in build 5142) always
start by bulding their own default configuration
(`config.js` and `sip-communicator.properties`, respectively).
The fact that we were generating these files ourselves was no longer of use,
because our configuration was thrown away in favor of the one created
by the containers on startup.
With this commit, we're completely redoing things. We no longer
generate these configuration files. We try to pass the proper
environment variables, so that Jitsi services can generate the
configuration files themselves.
Besides that, we try to use the "custom configuration" mechanism
provided by Jitsi Web and Jitsi JVB (`custom-config.js` and
`custom-sip-communicator.properties`, respectively), so that
we and our users can inject additional configuration.
Some configuration options we had are gone now. Others are no longer
controllable via variables and need to be injected using
the `_config_extension` variables that we provide.
The validation logic that is part of the role should take care
to inform people about how to upgrade (if they're using some custom
configuration, which needs special care now). Most users should not
have to do anything special though.
You may want to limit the number of video feeds forwarded to each client, to save up resources on both server and clients. As clients’ bandwidth and CPU may not bear the load, use this setting to avoid lag and crashes.
This feature is found by default in other webconference applications such as Office 365 Teams (limit is set to 4).
Read how it works [here](https://github.com/jitsi/jitsi-videobridge/blob/master/doc/last-n.md) and performance evaluation on this [study](https://jitsi.org/wp-content/uploads/2016/12/nossdav2015lastn.pdf)
You may want to **suspend unused video layers** until they are requested again, to save up resources on both server and clients.
Read more on this feature [here](https://jitsi.org/blog/new-off-stage-layer-suppression-feature/)
For this add this line to your `inventory/host_vars/matrix.DOMAIN/vars.yml` configuration:
```yaml
matrix_jitsi_web_config_channelLastN: 4
```
You may wish to **disable audio levels** to avoid excessive refresh of the client-side page and decrease the CPU consumption involved.
To enable the variables that allow you to manage the video configuration you must add the following line to your `inventory/host_vars/matrix.DOMAIN/vars.yml` configuration:
```yaml
matrix_jitsi_web_config_constraints_enabled: true
```

You may want to limit the maximum video resolution, to save up resources on both server and clients.
For example, to set resolution to 480.
For this add this two lines to your `inventory/host_vars/matrix.DOMAIN/vars.yml` configuration:

# Custom configuration to be injected into `interface_config.js`, passed to Jitsi Web.
# This configuration gets appended to the final interface configuration that Jitsi Web uses.
#
# Note: not to be confused with `matrix_jitsi_web_custom_config_extension`.
#
# For interface configuration, the flow is like this:
# - the contents of `templates/web/interface_config.js.j2` is generated (based on various `matrix_jitsi_web_interface_config_*` variables you see in this file)
# - the contents of `matrix_jitsi_web_custom_interface_config_extension` is appended and can define new settings or override defaults.
