Save conference video to local in server

[LuThaiHoc]

Question

Hi,
I'm using Flexisip in SFU mode for video conferencing, and I need to access the media streams during a conference. My goal is to:
Decode the video streams.
Mix the decoded streams.
Save the mixed stream locally.
What is the best approach to achieve this? Are there any recommended methods, APIs, or examples for accessing and processing media streams in SFU mode with Flexisip?
Thank you in advance!
