Word of caution: its a hack Add this to the intent intent.putExtra(“android.intent.extras.CAMERA_FACING”, 1); This solution isn’t sustainable, its using a testing code of the Camera app. For more info look at the “getCameraFacingIntentExtras” static method in Util class of the AOSP Camera project. Update: Looks like that it was disabled in L
Check out https://simpl.info/getusermedia/sources/ that shows how you can select sources using MediaStreamTrack.getSources(gotSources); You can then select the source and pass it in as optional into getUserMedia var constraints = { audio: { optional: [{sourceId: audioSource}] }, video: { optional: [{sourceId: videoSource}] } }; navigator.getUserMedia(constraints, successCallback, errorCallback); It is now fully available in Stable Chrome and … Read more
Android 3.0 Honeycomb added Device API support. Google I/O 2011 presentation shows an example on slide 30: <input type=”file” accept=”image/*;capture=camera”> It also points to a test site that not surprisingly does not do much on my Froyo phone. Anybody with a tablet tried it and can tell us what it does and does not do? … Read more
The picture is always taken in the orientation the camera is built into the device. To get your image rotated correctly you’ll have to read the orientation information that is stored into the picture (EXIF meta data). There it is stored how the device was oriented, when the image was taken. Here is some code … Read more
please see below answer. Custom_CameraActivity.java public class Custom_CameraActivity extends Activity { private Camera mCamera; private CameraPreview mCameraPreview; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mCamera = getCameraInstance(); mCameraPreview = new CameraPreview(this, mCamera); FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview); preview.addView(mCameraPreview); Button captureButton = (Button) findViewById(R.id.button_capture); captureButton.setOnClickListener(new View.OnClickListener() … Read more
I also faced same issue in Samsung devices, later I implemented ExifInterface and solved successfully. In any mode images will be shot it will always store in portrait mode only, and while fetching too returning in portrait mode. below of code I used to achieve my goal, I implemented within back camera, not sure about … Read more
My problem was much simpler 🙂 All I had to do is cancel previously called autofocus. Basically the correct order of actions is this: protected void focusOnTouch(MotionEvent event) { if (camera != null) { camera.cancelAutoFocus(); Rect focusRect = calculateTapArea(event.getX(), event.getY(), 1f); Rect meteringRect = calculateTapArea(event.getX(), event.getY(), 1.5f); Parameters parameters = camera.getParameters(); parameters.setFocusMode(Parameters.FOCUS_MODE_AUTO); parameters.setFocusAreas(Lists.newArrayList(new Camera.Area(focusRect, 1000))); … Read more
Although the documentation suggests that you can set which format the image data should arrive from the camera in, in practice you often have a choice of one: NV21, a YUV format. For lots of information on this format see http://www.fourcc.org/yuv.php#NV21 and for information on the theory behind converting it to RGB see http://www.fourcc.org/fccyvrgb.php. There … Read more
MSM_CAM_IOCTL_GET_PICTURE is a kernel call which runs the function static int msm_get_pic(struct msm_sync *sync, void __user *arg) I downloaded the kernel source for your device from the HTCdev and found the function defined in drivers/media/video/msm/msm_camera-7×30.c Could check what are the kernel messages when you take a picture? adb shell su -c “dmesg”
I think this function is not passing the correct endpoint int status = connection.bulkTransfer(endpoint, getEvent, getEvent.length, TIMEOUT); which is coming from UsbInterface intf = device.getInterface(0); UsbEndpoint endpoint = intf.getEndpoint(0); maybe the USB interface is not correct. Please check if index 0 parameter is correct.
