Hi,
Can mediasoup consume RTSP stream? If I have an URL like rtsp://username:password@address/to/abc.sdp?camera=1 , how to consume this using mediasoup v3.
No, mediasoup only supports WebRTC and plain RTP (optionally with SRTP).
You can pull that with external tool like FFmpeg or GStreamer and then send as RTP to mediasoup.
