Ever since the Chromecast came out, we've been wondering when an official screen mirroring feature would show up. Rather than wait, Koush is already working on that with the Mirror beta app. The functionality is limited right now, and of course, is still only accessible to those in the beta program. You might want to check it out, because Koush has pushed a new version with preliminary support for Chromecast mirroring.
Since the dawn of time, owners of Tegra devices have wanted a way to natively capture video of what's happening on their screen. Unfortunately, none of the existing apps (including Screencast) were able to accomplish this goal – until now.
Say hello to the [somewhat] recently-released SCR Screen Recorder, an app that not only promises to capture screencasts of Tegra devices, but delivers on that promise beautifully. To put the app to the test, I not only gave it a run on my Nexus 7, but broke the Galaxy Tab 10.1 out of the vault to ensure Tegra 2 compatibility.
