OpenVidu for large number of conferences

How to implement?
1

Will it be possible to use OpenVidu for many-to-many conferences for about 1000+ concurrent conferences, with each conference having 5 - 10 participants? If so what kind of hardware infrastructure you suggest?

Thank you very much in advance.

Yes, you can use OpenVidu PRO for such scenario.

In a 4 CPU machine you can manage 7 sessions with 7 participants. Then, for 1000 concurrent conferences with 7 participants each you will need 143 machines with 4 CPUs (or 72 machines with 8 CPUs…, or 36 machines with 16 CPUs each…). Also, you will need a powerfull master node with 8 CPUs.

Thank you Micael for the prompt response.

Is there any maximum limit for the number of participants per session for video conferencing? In our proposed scenario there could be more participants per session, like 25 or 30.

Is it possible to setup OpenVidu PRO version in our own premises? I understand that OpenVidu PRO has a per usage cost. Is there a per usage cost even if it is installed in our own premises?

Thank you in advance.

You can have 25/30 participants on the same session, but depending on the topology, you will need 8 CPU machines to manage it.

OpenVidu PRO must to be installed on your premises or in any cloud provider.

Thank you Micael.
The video resolution suggested is 720p with a need to enhance to 1080p in certain situations, while on the call. Is it possible, or any suggestion to manage this situation?

Thank you in advance.

It is possible to select resolution with publisher starts publishing. You have to play a bit with native WebRTC objects, but it can be done.

Seems the OpenVidu consumes the CPU heavily. I think it is because of the media processing, especially mixing. If that assumption is correct, is there a way to selectively opt for media mixing from the client application?

Thanks in advance.

OpenVidu doesn’t do any mixing under the hood. The CPU consumption is high because media processing (decryption, depacketization, etc…)

Thank you. So is OpenVidu an SFU or MCU?

OpenVidu uses Kurento Media Server under the hood as an SFU.
