Recording script not working for Xiaomia for android App

We are try to records the call form our app its working fine for all other device except Xiaomi Note 3 and other MI devices . is any ways or setting need to change for run properly this below recording code in Xiaomi type device
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(fname);
try {
recorder.prepare();
recorder.start();
recording=true;

MediaRecorder, start failed: -19

Has anyone managed to successfully record a video using MediaRecorder on Glass?
This is the code i am using in order to prepare the Recorder. I keep getting error -19.
recorder = new MediaRecorder();
recorder.setOutputFile(videoFile);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setVideoFrameRate(15);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
Thank you.
Update:
It seems to be a GDK bug. I have reported it and it got accepted. If you are having the same issue just star the bug report to stay informed:
https://code.google.com/p/google-glass-api/issues/detail?id=360

To start video capture on Glass it seems that you have to completely stop the video preview. If you are using a previewing camera, prior of doing anything with a MediaRecorder, just run:
try {
mCamera.setPreviewDisplay(null);
} catch (java.io.IOException ioe) {
Log.d(TAG, "IOException nullifying preview display: " + ioe.getMessage());
}
mCamera.stopPreview();
mCamera.unlock();
More info here: https://code.google.com/p/google-glass-api/issues/detail?id=360#c6

After much frustration and iteration, I'm pleased to report that it IS possible to use MediaRecorder on Glass XE12. The below code works for me on my Glass Version 1 running XE12:
mMediaRecorder = new MediaRecorder();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setPreviewDisplay(preview.getHolder().getSurface());
mCamera.unlock();
// Step 2: Set sources
mMediaRecorder.setOnErrorListener(new android.media.MediaRecorder.OnErrorListener() {
public void onError(MediaRecorder mediarecorder1, int k, int i1)
{
Log.e(TAG,String.format("Media Recorder error: k=%d, i1=%d", k, i1));
}
});
mMediaRecorder.setVideoSource(0);
mMediaRecorder.setAudioSource(0);
mMediaRecorder.setOutputFormat(2);
mMediaRecorder.setVideoEncoder(2);
mMediaRecorder.setVideoEncodingBitRate(0x4c4b40);
mMediaRecorder.setVideoFrameRate(30);
mMediaRecorder.setVideoSize(1280, 720);
mMediaRecorder.setAudioChannels(2);
mMediaRecorder.setAudioEncoder(3);
mMediaRecorder.setAudioEncodingBitRate(0x17700);
mMediaRecorder.setAudioSamplingRate(44100);
mMediaRecorder.setMaxDuration(0);
mMediaRecorder.setOutputFile(getOutputMediaFile(MEDIA_TYPE_VIDEO).toString());
mMediaRecorder.setMaxDuration(-1);
// Step 5: Set the preview output
// Step 6: Prepare configured MediaRecorder
try {
mMediaRecorder.prepare();
mMediaRecorder.start();
} catch (IllegalStateException e) {
Log.d(TAG, "IllegalStateException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
} catch (IOException e) {
Log.d(TAG, "IOException preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
} catch (Exception e) {
Log.d(TAG, "Unknown exception preparing MediaRecorder: " + e.getMessage());
releaseMediaRecorder();
return false;
}

When do you prepare the recorder, is it something that happens when you launch your application? If so, are you launching it with a voice trigger?
If both of those things are true, this might be an instance of the bug described here. Can you try the workaround in that thread (exponential backoff) and see if it works?

Error opening android camera for streaming video

I'm trying to write video stream from my Galaxy Tab to server.
according to this manual i should do something like this:
frontCamera = getFrontCamera();
if((socket!= null)&&(frontCamera!=null))
{
try {
frontCamera.setPreviewDisplay(cameraPreview.getHolder());
} catch (IOException e1) {
// TODO Auto-generated catch block
Log.e("","",e1);
}
frontCamera.startPreview();
recorder = new MediaRecorder();
frontCamera.unlock();
recorder.setCamera(frontCamera);
recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setProfile(CamcorderProfile.get( CamcorderProfile.QUALITY_HIGH));
pfd = ParcelFileDescriptor.fromSocket(socket);
recorder.setOutputFile(pfd.getFileDescriptor());
recorder.setPreviewDisplay(cameraPreview.getHolder().getSurface());
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
Log.e("","",e);
} catch (IOException e) {
// TODO Auto-generated catch block
Log.e("","",e);
}
but all fails on step recorder.start(); with strange error
02-01 19:03:39.265: E/MediaRecorder(11922): start failed: -19
what does that mean and what should I do to start recorder?
UPD:
Trouble happens because of my getFrontCamera method. when I replace it with camera.open() all works correct.
protected Camera getFrontCamera()
{
Camera.CameraInfo inf = new Camera.CameraInfo();
for(int i = 0; i< Camera.getNumberOfCameras(); i++)
{
Camera.getCameraInfo(i, inf);
if(inf.facing==Camera.CameraInfo.CAMERA_FACING_FRONT)
{
return Camera.open(i);
}
}
return null;
}
Upd2 - yes, explicit setting of format and encoders solved the trouble -
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
Maybe because of pre-build formats are for back camera... But strange anyway.

I don't see output format setup, so try adding to recorder set up:
recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);

Have a look
And though it is streaming video, so that set -
recorder.setOutputFormat(8);
recorder.setOutputFile(socketFd);
Have fun.

I've a hack here, extending media recorder class and removing super.setVideoFrameRate(rate) solves the problem for me.

If you still want to use CamcorderProfile.QUALITY_HIGH with the front camera, you can use the following:
CamcorderProfile camcorderProfile = CamcorderProfile.get(currentCameraId, CamcorderProfile.QUALITY_HIGH);
recorder.setProfile(camcorderProfile);
where int currentCameraId is Camera.CameraInfo.CAMERA_FACING_BACK or ...FRONT
So the profile is indeed dependent on the camera (for high-end phones it appears to work fine without the distinction, since they all support 1080p by now, but low-end phones may crash otherwise)

android: record audio with MediaPlayer on emulator

I am trying to record audio from the microphone on the Android emulator with this code:
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(Environment.getExternalStorageDirectory() + "/test/test.3gp");
try {
recorder.prepare();
}
catch (IOException io) {
Log.v(LOG_TAG, "Could not prepare the audio " + io.getMessage());
}
recorder.start();
For stopping the audio, this is the code:
recorder.stop();
recorder.reset();
recorder.release();
The recording process works fine but the resulting audio that is distorted. When I record an audio for 60 seconds duration and play it, it's duration is being shown as 120 seconds. The measurement is not exact but the this is just to give you an idea.
Only the AMR_NB encoder is working on my emulator. I have tried different output formats but the result is always the same.
Is it a limitation of the emulator or am I doing something wrong here?
Edit 1:
I have tried the AudioRecord class too and the result is the same dragging audio.
Thanks.

I have been working for the same and found the solution, Try using the following code:
private void startRecording()
{
this.recorder = new MediaRecorder();
this.recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
this.recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
this.recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
MediaRecorder.getAudioSourceMax();
this.recorder.setOutputFile(this.getFilename());
this.recorder.setOnErrorListener(this.errorListener);
this.recorder.setOnInfoListener(this.infoListener);
try
{
this.recorder.prepare();
this.recorder.start();
} catch (final IllegalStateException e)
{
e.printStackTrace();
} catch (final IOException e)
{
e.printStackTrace();
}
}
This is working perfactly. Hope it helps you :)

Video quality in android?

I am using the media recorder class for recording video, I initialize the recorder with following properties,
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
But the quality of video is not as same as video I shoot over native android camera, my video recorded using media recorder is of poor quality as compared to the native one, how can I improve the video quality.
If any one knows me help me out.Thanks

Finally I found the code to record high quality video in android 2.1 by setting videEncodingBitRate , AudioEncodingBitRate, AudioSamplingRate ...etc. Using this method you can set the properties for video whatever you want to provide high quality video.
For setting high quality and low quality parameter refer this page,
http://www.andgps.com/20110410/camcorderprofile-predefined-camcorder-profile-settings-for-camcorder-applications
The code i used with base version android 2.1 to produce high quality video is shown below,
recorder = new MediaRecorder();
Method[] methods = recorder.getClass().getMethods();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setVideoFrameRate(24);
recorder.setVideoSize(720, 480);
for (Method method: methods){
try{
if (method.getName().equals("setAudioChannels")){
method.invoke(recorder, String.format("audio-param-number-of-channels=%d", 1));
}
else if(method.getName().equals("setAudioEncodingBitRate")){
method.invoke(recorder,12200);
}
else if(method.getName().equals("setVideoEncodingBitRate")){
method.invoke(recorder, 3000000);
}
else if(method.getName().equals("setAudioSamplingRate")){
method.invoke(recorder,8000);
}
else if(method.getName().equals("setVideoFrameRate")){
method.invoke(recorder,24);
}
}catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
`

use the following settings for Video Recordings:-
private void cameraSettings()
{
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setVideoSize(width, height);
mediaRecorder.setVideoFrameRate(videoFramePerSecond);
}
use videoFramePerSecond = 30 and width = 1280 and height= 720..
This setting you can do by your own as per your requirment.

try this
mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
mrec.setPreviewDisplay(surfaceHolder.getSurface());

Try adding this line
recorder.setVideoSize(640,480);
Or check out the screen resolutions supported by your device and set the best one accordingly.

To enhance the video quality, you should consider setting the video size on your mediaRecorder instance to the max resolution of your device.
This snippet will do the job
WindowManager wm = (WindowManager) getBaseContext().getSystemService(Context.WINDOW_SERVICE);
Point size = new Point();
wm.getDefaultDisplay().getRealSize(size);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);
mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mMediaRecorder.setOutputFile(file.toString());
mMediaRecorder.setVideoEncodingBitRate(10000000);
mMediaRecorder.setVideoFrameRate(30);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.HEVC);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
mMediaRecorder.setVideoSize(size.y, size.x);
int rotation =getWindowManager().getDefaultDisplay().getRotation();
switch (mSensorOrientation) {
case SENSOR_ORIENTATION_DEFAULT_DEGREES:
mMediaRecorder.setOrientationHint(DEFAULT_ORIENTATIONS.get(rotation));
break;
case SENSOR_ORIENTATION_INVERSE_DEGREES:
mMediaRecorder.setOrientationHint(INVERSE_ORIENTATIONS.get(rotation));
break;
}
mMediaRecorder.prepare();
