Setting resolution for recording

OpenVidu v2 Issues with deployment
1

How can I set the resolution of the recording without effecting the resolution while streaming?
I have used recordingMode as ALWAYS.

You can use a different resoulition if you’re using COMPOSED recording in the resolution body parameter of the recoding API call /api/recordings/start: https://docs.openvidu.io/en/stable/reference-docs/REST-API/#post-apirecordingsstart

If you’re using Node or Java Client this section would be usefull too to check: https://docs.openvidu.io/en/2.15.0/advanced-features/recording/#2-configure-your-sessions-to-be-recorded

Hi Cruizba,
I am following https://docs.openvidu.io/en/2.15.0/deployment/deploying-on-premises/ and https://docs.openvidu.io/en/2.15.0/developing/
Is there any way I can set recording resolution in openvidu-call-back or openvidu-call-front application?

I have used recordingMode as ALWAYS.

Ok so if I understand you correctly what you did is to modify openvidu-call-back to start sessions with recordingMode: ALWAYS

In this case it is not possible to set resolution. But you can do this:
In your openvidu-call-back endpoint where the sessions are created:

  1. Create a session with recordingMode: ALWAYS
  2. Check if the session is recording: https://docs.openvidu.io/en/2.15.0/reference-docs/REST-API/#get-apirecordingsltrecording_idgt
  3. If it is not recording, start the recording with custom properties: https://docs.openvidu.io/en/2.15.0/reference-docs/REST-API/#post-apirecordingsstart. If it is recording, do nothing.

Recordings will be stopped automatically when no user is streaming in 120 seconds.

TLDR: This is not implemented. You need to manage your recordings in your openvidu-call-back with some logic that “autostart” recordings with http requests instead of let OpenVidu manage recordings.

You’re always free to do a “Request for enhacement” and we can consider implement this: https://openvidu.discourse.group/c/request-for-feature/11

Hi,

I do not want to keep a check of session has started or not, whenever call starts recording must start.
Where can I trigger the recording manual recording?
Can you let me know the file and function where I can put the REST api request to always start recording?

6

With custom resolution, it is not possible right now. The recodingMode: ALWAYS don’t accept custom properties.

7

With recodingMode: MANUAL, how can I trigger the video when session is initiated? which fucntion I can put my REST api to start the recording?
If I call the recording api in createSession function inside OpenviduService file. it gives me 406 error.
In callController.ts also same issue.

That’s because no users has joined to the session, it is stated here: OpenVidu Docs

Use OpenVidu Webhooks to listen to events in your server:
- Webhook: OpenVidu Docs
- Events: OpenVidu Docs

If you listen to participantjoined you can check by the sessionId if the recording is active and if not, start it.

Thanks a million.
Will try to achieve this.

Suggesting you to mention this in docs page
