I am trying to write video to socket (with ParcelFileDescriptor). But when calling mediaPlayer.start() method - an IllegalStateException occurs with this message - "E/MediaRecorder: start failed: -38".
Code for file descriptor (Socket is 100% properly connected by the time programm calls it):
public ParcelFileDescriptor getFileDescriptorToSocket() {
return ParcelFileDescriptor.fromSocket(socket);
}
Preparing media recorder:
private boolean prepareMediaRecorder() {
mediaRecorder = new MediaRecorder();
camera.unlock();
mediaRecorder.setCamera(camera);
// mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mediaRecorder.setPreviewDisplay(cameraSurface.getHolder().getSurface());
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mediaRecorder.setVideoSize(320, 240);
mediaRecorder.setVideoFrameRate(30);
//mediaRecorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_720P));
mediaRecorder.setOutputFile(MainActivity.socketClient.getFileDescriptorToSocket().getFileDescriptor());
try {
mediaRecorder.prepare();
} catch (IllegalStateException ise) {
// TODO Delete test code
Log.d(TAG, "Error during MediaRecorder preparing: " + ise.getMessage());
ise.printStackTrace();
releaseMediaRecorder();
return false;
} catch (IOException ioe) {
// TODO Delete test code
Log.d(TAG, "Error during MediaRecorder preparing: " + ioe.getMessage());
ioe.printStackTrace();
releaseMediaRecorder();
return false;
}
return true;
}
and call for start recording:
private void startRecording() {
if (!prepareMediaRecorder()) {
// TODO Delete test code
Log.d(TAG, "Error starting recording process");
finish();
} else {
new Thread(new Runnable() {
#Override
public void run() {
try {
mediaRecorder.start();
} catch (Exception e) {
// TODO Delete test code
Log.d(TAG, "Error in recording thread: " + e.getMessage());
e.printStackTrace();
}
}
}).start();
recordingStatus = true;
}
}
I should note that when i disable start recording method - camera works fine - i can properly see camera preview surface.
Hello i have create a small application in which i am recording audio. My problem is, in following code i can create a file in specific folder but when i am trying to play this audio file it says this media file is not supporting. plz help
public void startRecording() {
System.out.println("STart Recording");
if (recorder != null) {
recorder.release();
} else {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
recorder.setOutputFile(getFilePath());
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
recorder.release();
}
}
}
private void stopRecording() {
System.out.println("Stop Recording");
try {
if (null != recorder) {
recorder.stop();
recorder.reset();
recorder.release();
recorder = null;
}
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
private String getFilePath() {
File rsd = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC);
if (!rsd.isDirectory()) {
rsd.mkdir();
}
File dcim = new File(rsd + "/hello.mp3");
return dcim.getAbsolutePath();
}
Yup like Ralph House said in comment, you should save your file with .3gp extention. Change
File dcim = new File(rsd + "/hello.mp3");
To:
File dcim = new File(rsd + "/hello.3gp");
Following code is not allowing to record a video. This code is invoked through a button but the button freezes. I am trying to use the camcorder profile to record the video.
public void startRecording() {
mCamera.unlock();
mrec.setCamera(mCamera);
CamcorderProfile cpHigh = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
mrec.setProfile(cpHigh);
File dir = new File(SdCardPath + Directory);
if (!dir.exists()) {
if (dir.mkdir()) {
Log.v(STORAGE_SERVICE, "Created directory");
} else {
Log.v(STORAGE_SERVICE, "Failed to create Directory");
}
}
FullFilePath = SdCardPath + Directory + RecordFileName;
mrec.setOutputFile(FullFilePath);
mrec.setPreviewDisplay(surfaceHolder.getSurface());
try {
mrec.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mrec.start();
}
Always do you best to catch exceptions thrown:
public void startRecording() {
try {
mCamera.unlock();
catch (RuntimeException ex){
// looks like camera was locked in the first place, who is using it?
}
mrec.setCamera(mCamera);
///...the rest of your code.
}
I'm trying to create a video recorder on Android, and I've prepared my code which is supposed to be working - but I constantly get an error message start failed: -19.
Here's my code:
public boolean startRecording() {
try {
camera.unlock();
mediaRecorder = new MediaRecorder();
mediaRecorder.setOnErrorListener(new MediaRecorder.OnErrorListener() {
#Override
public void onError(MediaRecorder mr, int what, int extra) {
Log.i(TAG, "Error");
}
});
mediaRecorder.setCamera(camera);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
Log.i(TAG, "a");
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
Log.i(TAG, "b");
mediaRecorder.setMaxDuration(maxDurationInMs); // set to 20000
String uniqueOutFile = OUTPUT_FILE + System.currentTimeMillis() + ".3gp";
File outFile = new File(uniqueOutFile);
if (outFile.exists()) {
outFile.delete();
}
mediaRecorder.setOutputFile(uniqueOutFile);
mediaRecorder.setVideoFrameRate(videoFramesPerSecond); // set to 20
mediaRecorder.setVideoSize(sView.getWidth(), sView.getHeight());
Log.i(TAG, "c");
mediaRecorder.setPreviewDisplay(holder.getSurface());
mediaRecorder.setMaxFileSize(maxFileSizeInBytes); // set to 50000
mediaRecorder.prepare();
Log.i(TAG, "d");
mediaRecorder.start();
Log.i(TAG, "e");
return true;
} catch (IllegalStateException e) {
Log.i(TAG, "f");
Log.e(TAG, e.getMessage());
e.printStackTrace();
camera.lock();
return false;
} catch (IOException e) {
Log.i(TAG, "g");
Log.e(TAG, e.getMessage());
e.printStackTrace();
camera.lock();
return false;
} catch (RuntimeException e) {
Log.i(TAG, "h");
Log.e(TAG, e.getMessage());
camera.lock();
return false;
}
}
All the debug logs (from "a" through "d") are printed in log, so it seems that all the steps upto mediaRecorder.prepare() are properly done. Then it catches a RuntimeException with message start failed: -19. There is a similar question, but that doesn't solve my problem.
Is there any other reason to get such an error?
Just found out the bug, in this line:
mediaRecorder.setVideoSize(sView.getWidth(), sView.getHeight());
after commenting out this line, the code runs perfectly!
I solved my problem once i added this for video recording
/**
* Start video recording by cleaning the old camera preview
*/
private void startVideoRecorder() {
// THIS IS NEEDED BECAUSE THE GLASS CURRENTLY THROWS AN ERROR OF
// "MediaRecorder start failed: -19"
// THIS WONT BE NEEDED INCASE OF PHONE AND TABLET
// This causes crash in glass kitkat version so remove it
// try {
// mCamera.setPreviewDisplay(null);
// } catch (java.io.IOException ioe) {
// Log.d(TAG,
// "IOException nullifying preview display: "
// + ioe.getMessage());
// }
// mCamera.stopPreview();
// mCamera.unlock();
recorder = new MediaRecorder();
// Let's initRecorder so we can record again
initRecorder();
}
/**
* Initialize video recorder to record video
*/
private void initRecorder() {
try {
File dir = new File(folderPath);
if (!dir.exists()) {
dir.mkdirs();
}
mCamera.stopPreview();
mCamera.unlock();
videofile = new File(dir, fileName + ".mp4");
recorder.setCamera(mCamera);
// Step 2: Set sources
recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
recorder.setProfile(CamcorderProfile
.get(CamcorderProfile.QUALITY_HIGH));
// Step 4: Set output file
recorder.setOutputFile(videofile.getAbsolutePath());
// Step 5: Set the preview output
recorder.setPreviewDisplay(mPreview.getHolder().getSurface());
// Step 6: Prepare configured MediaRecorder
recorder.setMaxDuration(video_duration * 1000);
recorder.setOnInfoListener(new OnInfoListener() {
#Override
public void onInfo(MediaRecorder mr, int what, int extra) {
if (what == MediaRecorder.MEDIA_RECORDER_INFO_MAX_DURATION_REACHED) {
mCamera.stopPreview();
releaseMediaRecorder();

Intent intent = new Intent();
intent.putExtra(CuxtomIntent.FILE_PATH,
videofile.getPath());
intent.putExtra(CuxtomIntent.FILE_TYPE, FILE_TYPE.VIDEO);

recorder.prepare();
recorder.start();

For detailed guide refer to this Open Source Cuxtom Cam
the problem is in your setVideoSize() code .
and why this code error ...
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()
run this code , and see whitch screen that your camera in your device can support :
final List<Camera.Size> mSupportedVideoSizes = getSupportedVideoSizes(mCamera);
for (Camera.Size str : mSupportedVideoSizes)
Log.e(TAG, "mSupportedVideoSizes "+str.width + ":" + str.height + " ... "
+ ((float) str.width / str.height));
and method is :
public List<Size> getSupportedVideoSizes(Camera camera) {
if (camera.getParameters().getSupportedVideoSizes() != null) {
return camera.getParameters().getSupportedVideoSizes();
} else {
// Video sizes may be null, which indicates that all the supported
// preview sizes are supported for video recording.
return camera.getParameters().getSupportedPreviewSizes();
}
}
I had that problem with some specific phones, I've found out that I couldn't set camcoder profile sizes in some of them. But when that worked for the problematic androids it stopped working on the previous working devices.
So in the end my implemented logic was something like:
Set width/height
Try to start the merdia recorder
In case of exception, try again without setting width/height
Kind of a trash logic, but that worked.
I've setup a github project with that implementation, try it out: https://github.com/rafaelsilverio/MediaRecorder
I also encountered this problem and annotated the following two ways, because the hardware does not support the two configurations.
MediaRecorder .setVideoSize（）
MediaRecorder .setVideoFrameRate（）
In my app i have audio section where i have one recordBtn that will record audio and one playRecordedAudioBtn that will play just recorded audio and i have one more playTrackBtn that will play track(musical audio).
when i click recordBtn and playTrackBtn, recorded audio must have what i have recorded and track song both but it is not recorded what i want and gives message in logcat
11-16 04:40:24.060: WARN/AudioFlinger(90): RecordThread: buffer overflow
my recorded audio code is below:
new Thread(recordingThread).start(); // called thread from onCreate

#Override
public void run() {

Toast.LENGTH_SHORT).show();
} else {

recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setAudioEncodingBitRate(16);
recorder.setAudioSamplingRate(44100);
recorder.setOutputFile(songTakePath);
try {
recorder.prepare();
} catch (Exception e) {
e.printStackTrace();
}
recorder.start();
}}
please provide any guidance and some code snippet.
thanks..
