Google recently started rolling out an updated version of its video calling app Duo. A teardown of the Duo APK conducted by Android Police reveals that the company has started testing the H.265 codec for video compression.
The H.265 codec is significantly better than the H.264 codec currently used by the app. It is a "widely supported standard on modern chipsets and delivers extremely good compression compared to H.264." The new codec is expected to greatly improve the video calling performance on the app, especially on slow and unreliable internet connections.
