I want to use the same plugin handle to watch different streams. But when I **stop** , then **watch(mtpointId)**, and **start()**, the stream does not play.

I observed that when I **stop**  
`{event: {janus: event, session_id: 6076152537598841, transaction: e0142190-a972-42c5-ba5b-c9a1137b702f, sender: 5451666764555511, plugindata: {plugin: janus.plugin.streaming, data: {streaming: event, result: {status: stopping}}}}, jsep: null}`

`{event: {janus: hangup, session_id: 6076152537598841, sender: 5451666764555511, reason: Close PC}, jsep: null}`

Is it okay to get **hangup** after stopping? But after getting **hangup**. I cannot use the handle to watch any other stream.

I tried **pause()**, but I did not get **hangup**. And when I reopen the stream I can play the stream just fine.

So, as I explained above, I did not get it to work. But I realized that I can only `watch` → `start` using the same handle once. After that, I should switch the mount points. That is for `RTP mount points only`, which was my case.

Closed.

You can definitely watch different mountpoints from the same handle, if you close the previous PeerConnection: try the stock demo, which does exactly that when you stop a mountpoint and then select a different one. To re-use the same PeerConnection, you can use the “switch” request too, but that only works if the mountpoints have the same codecs and media order.

Thank you for replying.

Yes, I read that I can play unlimited mount points concurrently using the same handle, which works while doing a `switch`.

But when I stop, watch,

wait for preparing  
`{streaming: event, result: {status: preparing}}`

and then start  
`{streaming: event, result: {status: starting}}`

I never get the `started` response.

This mostly happens when user A is watching a mount point and user B destroys the mount point. Now, user A cannot watch another mount point.

Check the Admin API for user A’s handle after the mountpoint is destroyed. The WebRTC PeerConnection should be closed: if it isn’t, maybe you’re trying to subscribe to something new and it doesn’t work because you still have something active.
