Improvements

Improved Video Quality

Video Stream Quality has improved through efficient Video Resolution Transition while down-scaling & up-scaling. Intermittent Video Freeze Issue has been overcome.

Effective Handling of ABWD

In order to the provide best user experience within the available bandwidth, system will try to optimize the picture resolution, frame rate and the number of streams that can to be shown to the end user.The SDK will provide event notifications when there are changes in link bandwidth conditions affecting the quality of the call so that developers may show these information to end user if desired.

Smooth reduction of the number of Video Streams, and moving to Audio Only Stream from Audio+Video Stream when Video Communication no longer feasible because of low bandwidth condition.

Stabililty

Crash Fixes and Process Optimization provides greater Stability of EnableeX v1.5 than its predecessors.
