Answer 1

It is possible using the Android Camera2 API, but as indicated above most devices don't have hardware support. If you have a Nexus 5X, Nexus 6, or Nexus 6P it will work and you can test with this BothCameras app. I've implemented blitting to allow video recording as well (in addition to still pictures) using the hardware h264 encoder.
