Energy usage

Testing energy usage with Xcode 7 and iOS 9 beta...

See also blog post.

Notes

The download runs at maximum network speed, so energy usage is quite high initially. Once buffering completes, the energy (and CPU) usage settles down.

Theora is currently built without the armv7/neon assembly optimizations.

VPX is pre-built with the build-ios.sh script.

Run the demo app in Xcode, then click on the Energy Report from the debug/device info sidebar.
