android mediarecorder error (MediaRecorder start failed :
When I try to make the camera recorder in my program I get this error:
E/MediaRecorder﹕ start failed: -19
code is
try {
final SurfaceView sv = (SurfaceView) findViewById(R.id.srvView);
MediaRecorder mrec = new MediaRecorder();
mrec.setCamera(camera);
mrec.setAudioSource(MediaRecorder.AudioSource.MIC);
mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mrec.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mrec.setVideoFrameRate(10);
mrec.setVideoSize(480, 320);
mrec.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mrec.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mrec.setPreviewDisplay(mSh.getSurface());
mrec.setOutputFile("/mnt/sdcard/pro/andsend.avi");
mrec.prepare();
mrec.start();
} catch(Exception e)
{
e.printStackTrace();
}
I try to change the sequence and change the set size, Frame Rate etc...
But, I can't find the problem.
What's the problem?
see my answer : android-mediarecorder-start-failed-19
error code -19 comes about when there is a problem with the size of the video as set by MediaRecorder#setVideoSize()
mrec.setOutputFile("/mnt/sdcard/pro/andsend.avi");
are you sure that this folder exist? Also edit this line to
mrec.setOutputFile(Environment.getExternalStorageDirectory() + "/pro/andsend.avi");
