Blank Video while recording

OpenVidu v2 Issues developing apps
1

Hi Micael,

We are facing an issue in the Openvidu.

Actually As per the openvidu Docs we have to open the mentioned below Ports.

  • 40000 - 57000 TCP+UDP: used by Kurento Media Server to establish media connections.
  • 57001 - 65535 TCP+UDP: used by TURN server to establish relayed media connections.
    But our Company is providing only below mentioned ports and we have enabled only the ports in yml file
  • 40000 - 40010 TCP: used by Kurento Media Server to establish media connections.
  • 57001 - 57011 TCP: used by TURN server to establish relayed media connections.

Using these ports only our application is running .1000 of users are recording at same time most of the videos getting blank. I want to know because of the ports the video is getting blank or some other issue is there?
Incase port is the issue can you help me ,how to restrict other users who are not using the above mentioned Ports.

We are facing this issue in production, Please do the needful as soon as possible .

Dear Pablo,

We are facing the blank video issue and we need to restrict the ports. We need your help to configure the ports .We are facing a Major issue in Production.Kindly please give me a reply as soon as Possible.

Kind Regards,
Jagadeesan

Seeing the error returned by openvidu-server, I am not really sure this is a problem related to opened ports. This message Timeout of 10000 milliseconds waiting from response to request is a symptom of the Media Server being overloaded. Are you monitoring the CPU load of the Media Node?

6

We had monitired CPU it is within 12-15% .But we dont have UDP ports available only 3478 tcp/udp ports are available.We are using CE Version 2.23.0 still we are facing the blank video.Kindly please helpe for this issue @pabloFuente

8

We are having some difficulty comprehending your current deployment setup.

Could you please provide us with information regarding the specific ports that are currently open on your system? And what files did you modified for that purpose?
Can you share your .env (protect your secrets) and docker-compose.yml files?

Additionally, we’re interested in pinpointing when the issue of blank recordings began to occur. Could you clarify if these blank recordings started appearing before or after you modified your opened ports?

PS: We made the topic public

In our organisation we have restriction of port ,so we cant enable the UDP ports.I had attached the .env and docker file .Kindly Please check @cruizba @pabloFuente

Ok.

As it is right now, the only thing that is not working are recordings? Please confirm this.

If that’s the case, can you enable: OPENVIDU_RECORDING_DEBUG=true ?

This will generate some useful logs in your recording folder so we can check what is happening in the recording container.
