    And what is that means? Please, tell us how this could be helpful for android users?

    @Chrizt:

    This page measures the CPU usage of two software libraries used to decode a piece of video. This information is important for Android software developers because then we can pick the most optimized algorithm to deliver a faster, smoother program for the user. For users, however, this information is probably not too useful 😛
