Hi
i've same problem with camera video recording
below my source code:
private boolean mediaRecorderConfig()
{
try
{
mediaRecorder = new MediaRecorder();
mediaRecorder.setCamera(mCamera);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setMaxDuration(maxDurationInMs);
mediaRecorder.setOutputFile("/sdcard/
myvideo.mp4");
mediaRecorder.setVideoFrameRate(videoFramesPerSecond);
mediaRecorder.setVideoSize(mSurfaceView.getWidth(),
mSurfaceView.getHeight());
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());
mediaRecorder.setMaxFileSize(maxFileSizeInBytes);
mediaRecorder.prepare();
}
catch (IOException e)
{
Log.e(TAG,e.getMessage());
e.printStackTrace();
return false;
}
return true;
}
private boolean startRecording()
{
try
{
mCamera.unlock();
if(!mediaRecorderConfig())
return false;
mediaRecorder.start();
recording = true;
return true;
}
catch (IllegalStateException e)
{
Log.e(TAG,e.getMessage());
e.printStackTrace();
return false;
}
}
private void stopRecording()
{
if(mediaRecorder != null)
mediaRecorder.stop();
if(mCamera != null)
mCamera.lock();
recording = false;
}
i have my problem when I execute:
mediaRecorder.start(); or mediaRecorder.stop();
I receive this cat log:
