Video Recording

[pavelupward]

I made the service that launches the camera and record video in the background, but the video quality is very low, I assigned mMediaRecorder.setVideoSize (1920, 1080); but nothing has changed. If I add here this mMediaRecorder.setProfile line (CamcorderProfile.get (CamcorderProfile.QUALITY_HIGH)); then logs see such a warning System.err: at com.hidecamera.camera.RecorderService.startRecording (RecorderService.java:115) and the camera does not start, and if I delete this line, the camera starts and record video in a very poor quality

Hi pavelupward,
Have you tried with the autofocus of the camera's parameter?
Like this
` // get Camera parameters
Camera.Parameters params = mCamera.getParameters();

    List<String> focusModes = params.getSupportedFocusModes();
    if (focusModes.contains(Camera.Parameters.FOCUS_MODE_AUTO)) {
        // Autofocus mode is supported
        params.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO);
        mCamera.setParameters(params);
    }`

Otherwise on the touch event of the camera

getActivity().runOnUiThread(new Runnable() { @Override public void run() { mCamera.cancelAutoFocus(); mCamera.autoFocus(new Camera.AutoFocusCallback() { @Override public void onAutoFocus(boolean success, Camera camera) { Log.d(TAG, "FOCUS"); } }); } });

@pavelupward Can you please guide me how to record video with the current plugin and where to add the above code?

[erperejildo]

@pavelupward can you provide more info about video recording?

[hartherbert]

Is there anybody with a plugin version where it is possible to record a video ?

[westonganger]

@vipulsharma144 has submitted PR #587 which completes the work done from @icetec-solutions implementation. I would appreciate if anyone has any comments on that PR.

[westonganger]

Video recording functionality for Android has been implemented in master via #587
