You don't need to do msg_apply_changes() after each sdpops change, unless you want that preview change to be visible for next operations. For example, you can call the function to remove a codec twice, once for g711 and once for g729 without msg_apply_change() and all should be fine. However, if you want to remove video media stream and then call rtpengine/rtpproxy, then the msg_apply_changes() would be required in order for rtp relay application not to see the video stream.
