Convos v4.08 is
fresh from the bakery, and this time we are proud to announce video support!
If you are just testing out Convos, you won’t see any button to start the video
chat. The reason for this is that the underlying technology require a
secure connection, a STUN server
and optionally a TURN server.
WebRTC will (probably) not function properly if you connect to Convos without a
secure connection. SSL certificates can either be bought or set up for free with
Let’s Encrypt. If you expose Convos directly on the
internet you can specify the certificates from the command line:
./script/convos daemon --listen "https://*:8443?cert=./server.crt&key=./server.key"
Keep in mind that the STUN and TURN server also require secure connections.
The absolute minimum to enable video support is a
STUN server. This server is needed for
clients to exchange basic information for how to reach each other.
To start Convos with a given STUN server, you need to specify the
CONVOS_STUN environment variable. Example:
CONVOS_STUN=stun://stun.services.mozilla.com:3478 ./script/convos daemon
A TURN server might be needed some cases where the network between the two
clients is “complicated”. The two clients will in that case send the video and
audio streams to the TURN server, instead of using peer-to-peer connections.
To start Convos with a given TURN server, you need to specify the
CONVOS_TURN environment variable. Example:
There are (to my knowledge) no free alternatives for this, so you have to set
up your own server for this. The Coturn
server also supports TURN, so you only need one external server to get a
video connection for all cases.
Once you have started Convos with the
CONVOS_STUN environment variable, you
can go to any conversation and there should be a video camera symbol on the
right side of the conversation name.
Clicking on the video button will notify the other user(s) in the conversation
that you are ready to video chat. Any other user can then join and you will
then see and hear each other.
The signalling protocol use IRC to send the WebRTC signals. The
is however specific for Convos, so you can only video chat with other people
who have the same Convos version as yourself.
There are several reasons why video support is currently marked as
We hope to stabilize video support in Convos
v5.00. It might sound like
that that is way into the future, but in reality Convos will jump from 4.xx to
5.00 once video support seems to work properly.
