VideoRoom V2 , How can i track when a publisher turns off his video ? about flutter_janus_client HOT 7 CLOSED

I am working on video room example optimization to illustrate all possible functionality with v2 api stay tuned

@Osamaegy Janus server emits unpublished events you can use that event to set null for that particular remoterender and update the ui accordingly

i have no good experience on video room but this is a Janus server event ....so if Janus does not receive video feed it will notify all the through server events ...within a time you specify in Janus config file (default is 1 second)

I have some question: how can I track, when some turns off his video/audio ?

@CoMatu janus server emit different event according to the state of webrtc of the device ... listen these event either by HTTP, websockets or MQTT (https://janus.conf.meetecho.com/docs/eventhandlers.html)
here is a good article from the main developers of the Janus webrtc server on events https://www.meetecho.com/blog/event-handlers-a-practical-example/

@kzawadi Thanks for the answer! Have yoy some expamles for mute/unmute microphone?

from flutter_janus_client.

Hello, @CoMatu ... muting and unmuting the mic is flutter side and you have to handle it I mean it's not Janus related or even webrtc related directly.... those are just media controllers ...The following is my ideal implementation... I have a button on flutter is has two states e.g mute and unmuting... when this button is used it creates an event that can be listened to by all devices on that audio session here am using a pubsub server (PubNub or google pubsub) as you can see up to this point no webrtc related stuff so far ... and so all devices on that conference call when they get a certain notification from that pubsub server they know what it means e.g the sender of this message we just got has muted his/her mic ... and other stuff like kicking a misbehaving user from the session... an admin can send a pubsub notification to all devices on that session and the client when getting the notification it executes a required function like leaving the session. another use case a user raises a hand ..what happens logically is they send a pubsub notification and an admin side gets a notification that a user has raised his/her hand and if an admin is okay letting you talk he will just click allow but logical again it's a pubsub notification transmitted with an allow notifications... So what about Janus Server ...Janus server automatically measures decibel levels and emit events according to the decibel level of the devices... events here are "talking" and "stop talking"... and you can adjust the level of the session when starting the client on creating a session/room or joining.
{"audio_level_average": <average value of audio level (127=muted, 0='too loud', default=25)>, "audiolevel_event" : <true|false (whether to emit event to other users or not)>,}

Thanks
