Hello @vipin_mishra,

It should work with the replaceTrack function, I do it like this (adapt the code to your needs):

OV.getUserMedia({
   audioSource: false,
   videoSource: undefined,
   resolution: '1280x720', // HERE WILL BE YOUR NEW RESOLUTION
   frameRate: 30 // HERE WILL BE YOUR NEW FRAMERATE
})
.then(mediaStream => {
    var videoTrack = mediaStream.getVideoTracks()[0];
    publisher.replaceTrack(videoTrack).then(function() {
        console.log('New track is being published');
    }).catch(function(error) {
        console.error('Error replacing track');
    });
});

Cheers,
Mihail
