OpenVidu stores videos in the /srv/videos-current/ folder, exempla /srv/videos-current/sessionid/sessionid.mp4.
I wanted the path to be customized, that is, /srv/videos-current/123/sessionid.mp4, 123 would be a dynamic variable, for example being the first 3 digits of the sessionid.
Is this possible?
In production, it is mandatory to have OpenVidu installed at /opt/. Why?
Because we want to have a common directory for all users so troubleshooting can sometimes helps more people if the installation procedure is the same across environments.
So, no, it is not possible to add a random number at the recordings directory.
What you can do is to create a service which listens to OpenVidu webhooks, and move those recordings when they finish to the folder you want and serve it as you wish.
