website update

i have a video call website coded in javascript based on WebRTC model and it uses a scaledrone API .. it works fine ..i have another page for text chat it also uses WebRTC and scaledrone ,, it establishes a datachannel for the text chat ..the problem is i am unable to merge these two pages into one ..if i do that ..either the text chat or the video chat loses functionality. Therefore, I need a person who can merge it and both text chat and video call works on the same page. I also need to add several buttons (such as change camera and mic inputs). And optionally , if you can add a recording button ..that would be great (its optional). If not clear, don't worry , i will explain in more details later.
