Add framework support for camcorder zoom. The purpose of ICameraRecordingProxy and ICameraRecordingProxyListener is to allow applications using the camera during recording. Camera service allows only one client at a time. Since camcorder application needs to own the camera to do things like zoom, the media recorder cannot access the camera directly during recording. So ICameraRecordingProxy is a proxy of ICamera, which allows the media recorder to start/stop the recording and release recording frames. ICameraRecordingProxyListener is an interface that allows the recorder to receive video frames during recording. ICameraRecordingProxy startRecording() stopRecording() releaseRecordingFrame() ICameraRecordingProxyListener dataCallbackTimestamp() The camcorder app opens the camera and starts the preview. The app passes ICamera and ICameraRecordingProxy to the media recorder by MediaRecorder::setCamera(). The recorder uses ICamera to setup the camera in MediaRecorder::start(). After setup, the recorder disconnects from camera service. The recorder calls ICameraRecordingProxy::startRecording() and passes a ICameraRecordingProxyListener to the app. The app connects back to camera service and starts the recording. The app owns the camera and can do things like zoom. The media recorder receives the video frames from the listener and releases them by ICameraRecordingProxy::releaseRecordingFrame. The recorder calls ICameraRecordingProxy::stopRecording() to stop the recording. The call sequences are as follows: 1. The app: Camera.unlock(). 2. The app: MediaRecorder.setCamera(). 3. Start recording (1) The app: MediaRecorder.start(). (2) The recorder: ICamera.unlock() and ICamera.disconnect(). (3) The recorder: ICameraRecordingProxy.startRecording(). (4) The app: ICamera.reconnect(). (5) The app: ICamera.startRecording(). 4. During recording (1) The recorder: receive frames from ICameraRecordingProxyListener.dataCallbackTimestamp() (2) The recorder: release frames by ICameraRecordingProxy.releaseRecordingFrame(). 5. Stop recording (1) The app: MediaRecorder.stop() (2) The recorder: ICameraRecordingProxy.stopRecording(). (3) The app: ICamera.stopRecording(). bug:2644213 Change-Id: I15269397defc25cbbcae16abc071c8349c123122 2011-06-01 17:22:24 +08:00			`ICameraService.cpp \`

Add camera service support for SurfaceTexture. This change enables the use of a SurfaceTexture in place of a Surface as the destination of camera preview frames. Change-Id: Ic70d404c8fe261e9d5da6f1de93d6babb5b191cb 2010-12-20 11:51:31 -08:00			`libui \`
