E2EE recording post process

[Sarbajit Bhattacharjee]

Hello Lorenzo,

How do i post process recordings after implementing E2EE? 

[ERR] [postprocessing/janus-pp-rec.c:main:1266] End-to-end encrypted media recording, can't process...

[Lorenzo Miniero]

You can't, obviously. If the stream you record is end-to-end encrypted, it means the server wasn't means to access to the media.

Then what can be the work around for this? Because as per our requirement, conference needs to be recorded and end to end encrypted

These two requirement cannot be met at the same time. If you want recording, it's one of the participants that needs to record the event: if anything else beyond participants can record the session, then it's not end-to-end encrypted, by definition.

If i want a participant to record all the streams, then can i follow below steps?

1. From a server side application, one participant joins as a subscriber in the same videoroom

2. Save each participant's audio+video in specific folder

3. After recording stop, merge video with ffmpeg
