Who can help me ??? It's my code

private boolean prepareVideoRecorder() {

            mediaRecorder = new MediaRecorder();

            if (Build.VERSION.SDK_INT < 14)
                    camera.unlock();
            mediaRecorder.setCamera(camera);
            mediaRecorder.setPreviewDisplay(preView.getHolder().getSurface());
            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
            mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

            mediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_LOW));
            mediaRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).getAbsolutePath());
            mediaRecorder.setPreviewDisplay(preView.getHolder().getSurface());
            try
                {
                    mediaRecorder.prepare();
                } catch (IOException e)
                {
                    e.printStackTrace();
                    releaseMediaRecorder();
                    return false;
                }

                {
                    mediaRecorder.stop();
                    releaseMediaRecorder();
                    if (Build.VERSION.SDK_INT < 14)
                        camera.lock();
                    button.setText("Capture");
                    isRecording = false;
                } else if (prepareVideoRecorder())
                {

I was also having the same issue and looked at all of those answers too =(. Tried a million things... and different ways of setting up MediaRecorder.

I just got it working and it was because I wasn't calling ->

android.hardware.Camera.unlock()

Read capturing videos section at top: https://developer.android.com/guide/topics/media/camera.html

I notice you are calling unlock as well but only for version lower than 14? Perhaps it needs to be called for all versions?

Sorry didnt read your new error that wasn't start failed -19 but to do with the surface. Ignore my answer if it is unrelated! I was searching for start failed error - 19 – Dave Thomas Aug 12 '16 at 23:44

Wow. I searched for hours with no solution working but this one actually worked! It kept failing on my Google Pixel (API 25). I found this solution surprising because it's supposed to be automatically handled. Thank you! – Pkmmte Dec 02 '16 at 03:14

From the research I have done, error code -19 comes about when there is a problem with the size of the video as set by MediaRecorder#setVideoSize()

Hi. How did you solve problem? How can we know which video size is supported? – TOP Sep 23 '15 at 08:13
