How to increase video quality/Resolution in OpenTok RTC(Real Time Communication)

2k views Asked by At

I am using OpenTok iOS SDK (Multi Party Call Demo). How can I increase video quality? I am having high speed internet connection during video call but video quality is not so good as it should be.

Any help will be appreciable.

On the iOS publisher side, the OpenTokRTC avoids that complexity as it is a demo app - but you can see:

  1. Where OpenTokRTC creates OTPublisher:
  2. In a different sample app, an example custom OTPublisher that uses a custom VideoCapture.
  3. Where the custom VideoCapture sets the resolution.

Combining these, you should be able to re-factor OpenTokRTC to use a custom OTPublisher where you can specify the resolution.

On the JS desktop publisher side, this is where OpenTokRTC creates the webcam publisher. Here is the JS documentation for setting webcam resolution.
