Galaxy, Nexus & fringe device support

Issue Recap: Nexus, Galaxy & Fringe Device Issues

Description: Camera errors and trouble determining facing or angle using Nexus handsets. Caused by its use of facing and rotation to form what would normally be a 0 or 1. Throws error code -38 when starting the MediaRecorder. This bug renders the app useless as stated in previous issues.

Reproducing: Using Haven and attempting to switch cameras when not actively previewing from the MonitorActivity would cause the Camera.open() call to return a null camera instance.

Buggy Workarounds: Avoid setting the audio source and format in MediaRecorderActivity. Alternatively, encode using h.263 instead of .264. Remove extraneous file separator from the videoFile path if necessary. This will give you a video file but the dependency used to play it back is old. You have to then export it to view, could be a data limit thing.

Conclusions: Setting the cameraFacing variable isn’t possible using a device that doesn’t provide a simple 0,1 camera configuration. Once lost, the app will crash when called a second time. For instance, when visiting MonitorView -> Settings -> Camera Sensitivity the parameters are attempting to be set on a null object after the Camera.open() call fails due to lack of a provided variable corresponding to the camera of the device.

• Causes video monitoring to crash when setting the audio output and encoder because media recorder is already active at that time from an outside process using the microphone
• Camera sensitivity in settings will crash if not accessed directly from the MonitorView
• Modification may help some devices and hurt others, further testing required.

e0ecdc6 fixes most all of this 👍 thank you! Issues above regarding video recording and bind handlers are mentioned eleewhere: #313, #295. Closing it up

Current mp4 encoding not working on nexus 4 & 5 causing no playback. BMP encoding seems to intensive for older devices.
