There are really two bugs here:
1) the screen goes black
2) you should not be able to switch cameras while recording in progress

Comments from a previous private bug suggest we are using the API incorrectly:
nexus 4 have the same error message while in front camera and doing video/photo mode switching.

E/CameraClient( 1129): native_window_api_connect failed: No such device
(-19)

If you enable log around native_window_api_connect and
native_window_api_disconnect in
frameworks/av/services/camera/libcameraservice/api1/CameraClient.cpp,
you will see it's connect more than twice before disconnect is called.
And on the document, it's said that you need to disconnect before re-
connect.

quote from system/core/include/system/window.h:
/*
 * native_window_api_connect(..., int api)
 * connects an API to this window. only one API can be connected at a time.
 * Returns -EINVAL if for some reason the window cannot be connected, which
 * can happen if it's connected to some other API.
 */
