Looking at the SDP theres no immediately obvious reason why it wouldnt be working on windows.
Both have the m=video tag with the same protocols, both are sendRecv.
The issue could be outside the scope of this package

Thank you for your reply.
This error is showing only on windows platform when starting a video call.

[ERROR:flutter/shell/common/shell.cc(1065)] The 'FlutterWebRTC/peerConnectionEvent673288A4-17BE-4C71-B37D-317209D238F9' channel sent a message from native to Flutter on a non-platform thread. Platform channel messages must be sent on the platform thread. Failure to do so may result in data loss or crashes, and must be fixed in the plugin or application code creating that channel.
