I am working on video recording app in which i want to display preview and when user click on record button it start recording and when user click stop button it stop recording.

I got camera preview and recording back camera is working fine.

But when I flip camera to front camera and when I start recording it occurs error like this:

FATAL EXCEPTION: main java.lang.RuntimeException: start failed. 
        at android.media.MediaRecorder.start(Native Method) at 
        com.opkix.app.fragments.CameraFragment.startRecording(
                                             CameraFragment.java:104)

Here's my code for recording video code:

private boolean prepareMediaRecorder() {
    // set the orientation here to enable portrait recording.

    mediaRecorder = new MediaRecorder();

    mCamera.unlock();

    mediaRecorder.setCamera(mCamera);

    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    mediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));


    mediaRecorder.setOutputFile(StorageUtils.getOutputMediaFilePath());
    mediaRecorder.setMaxDuration(120000); // Set max duration 60 sec.
    mediaRecorder.setMaxFileSize(100000000); // Set max file size 50Mb

    mediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
    try {
        mediaRecorder.prepare();
    } catch (IllegalStateException e) {
        releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        releaseMediaRecorder();
        return false;
    }
    return true;

}

Can anyone please suggest solution?

  • Take a look at [this](http://stackoverflow.com/q/10496969/1553851) and [this](http://stackoverflow.com/q/11249642/1553851). – shmosel Jan 10 '17 at 03:44
  • also use some other method in your app.which is helpful on Video recording according to your App..[e.g. release camera & media recorder].because without use of that method Recording will crash your App. – Sagar Aghara Jan 10 '17 at 03:59
  • @shmosel Hello, I already tried those solutions but those are for both back and front camera, but I'm facing only for front camera. could you please suggest me better solution? – Ioan Moldovan Jan 10 '17 at 09:36

now, i am also working on Video Recording App.Please one time Run your Code in some another device's.also i am sharing my Code with you.in which some of code is my App related code.remove that if you don't need that.

My Code : 

private boolean prepareVideoRecorder() {
    mRecorder = new MediaRecorder();

    // Both are required for Portrait Video
    mCamera.setDisplayOrientation(90);
    if (mCameraId == CAMERA_FACING_FRONT) {
        mRecorder.setOrientationHint(270);
    } else {
        mRecorder.setOrientationHint(90);
    }

    // Step 1: Unlock and set camera to MediaRecorder
    mCamera.unlock();
    mRecorder.setCamera(mCamera);

    // Step 2: Set sources
    mRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
    mRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);

    // Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
    mRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_480P));

    // Step 4: Set output file
    final File folder;
    if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        folder = new File(Environment.getExternalStorageDirectory() + "/CameraApp/Videos");
    } else {
        folder = new File(Environment.getExternalStorageDirectory() + "/CameraApp/Videos");
    }

    boolean success = true;
    File videoFile;
    if (!folder.exists()) {
        success = folder.mkdirs();
    }
    if (success) {
        videoFile = new File(folder.getAbsolutePath() + File.separator + getFileNameCustomFormat() + " " + ".mp4");

        SavedVideoPath = getFileNameCustomFormat() + " " + ".mp4";
        Log.e("Video Path - ", SavedVideoPath);
    } else {
        Toast.makeText(getBaseContext(), "Video Not saved", Toast.LENGTH_SHORT).show();
        return true;
    }
    mRecorder.setOutputFile(String.valueOf(videoFile));

    // mRecorder.setVideoSize(mPreviewWidth, mPreviewHeight);

    // Step 5: Set the preview output
    mRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());

    // Step 6: Prepare configured MediaRecorder
    try {
        mRecorder.prepare();
    } catch (IllegalStateException e) {
        Toast.makeText(getApplicationContext(), "prepareVideoRecorder() Exception: " + e.getMessage(), Toast.LENGTH_LONG).show();
        releaseMediaRecorder();
        return false;
    } catch (IOException e) {
        Toast.makeText(getApplicationContext(), "prepareVideoRecorder() Exception: " + e.getMessage(), Toast.LENGTH_LONG).show();
        releaseMediaRecorder();
        return false;
    }
    return true;
}

And let me know what happen.? after trying my code. Hope this will Helps :
