Recreate codec and display on rotation changed

On some devices, we can reuse the same codec and display, but on some
others (e.g. Nexus 5X with Android 7.1.2), it crashes on codec.stop()
with an IllegalStateException.

Therefore, always recreate the codec and display, so that it works on
all devices.
