Initially user (server) started with video ON in Jitsi meet desktop app… that time Video is ON.
—>This is expected behaviour and looks good.
Whenever a user (client) is joining the same meeting from jitsi meet SDK app, the video is ON for the client user and the video is OFF for the server user.
-----> It should keep the video ON for server user.
This is not something we maintain, so you may turn to the maintainer of that project. That uses a pretty old SDK so it is probably not compatible with the latest jitsi-meet. Not sure what deployment you are using, but if you are using meet.jit.si make sure you use it only for testing and when you will be releasing something host your own deployment or subscribe for jaas, so you do not violate the terms and conditions of meet.jit.si
