Developing the User Interface
Designing the user interface is an integral part of develop react native video calling app. It determines the usability and overall user experience of your video calling application.
Designing the Call Screen Layout
The call screen layout should be intuitive and easy to navigate. Display the local video stream (user's own video) and remote video stream (other participant's video) prominently. Include controls for muting/unmuting audio, switching camera, ending the call, and accessing other features. Consider different layouts for one-on-one calls and group video conferences. The Call screen has to support different network conditions.
Implementing User Controls (e.g., Mute, Camera Switch)
Provide users with easy-to-use controls for managing their video and audio. Implement buttons or toggles for muting/unmuting audio, switching between front and rear cameras, and enabling/disabling video. Ensure that these controls are easily accessible during a call. The controls must be easy to use while also not interfering with the video stream.
Handling Incoming and Outgoing Calls
Implement a mechanism for handling incoming and outgoing calls. Display a notification or alert when a user receives an incoming call. Provide options to accept or decline the call. Show a call progress indicator during outgoing calls. The implementation should also handle network drops and error scenarios.
JavaScript: React Native code for displaying a remote video stream
