Hello

I am concerned by this same problem: : [detecting consumer closed/ track ended](https://mediasoup.discourse.group/t/detecting-consumer-closed-track-ended/592)

The “User Logged Out” system cannot be made by displaying it to both the sender and the recipient.

Do you know where to place this code JavaScript:

```auto
consumer.on("transportclose", async () => {
	console.warn("consumer.close() by transportclose");
	this.emit("@consumerDisconnected", { nickname: "test is disconnected" });
});

```

For the transmitter, it is placed here:

```auto
 async sendVideo(track) {
    console.warn("room.sendVideo()");
    const videoProducer = await this.sendTransport.produce({
      track
    });
    videoProducer.on("trackended", async () => {
      console.warn("producer.close() by trackended");
      await this._closeProducer(videoProducer);
    });
    return videoProducer;
  }

```

But I don’t know where to place the transportclose,

do you have an idea ?

The thread that you are addressing points to a generic WebRTC problem, so even though there is an event on mediasoup-client for trackended it does not get fired because of browser implementation.

You can do this out of band, and inform consumers about when a transport / producer ends on the server using an external mechanism like WebSocket.

But if you’re still thinking of doing it in band. Your best bet is still:

```auto
consumer.on(“trackended”, fn())

```
