Hello,
I have a problem with MediaRecorder. I want to record video. But fail
to prepare the MediaRecorder.
Here is the logs and source code. Is there anything wrong?
In the logs, [Failed to get camera(0x32e58) parameters].
I think that this is due to.
Why failed to get camera parameters?
Also, what should I do?
- Environment
-- Dev phone 1
-- OS 1.6
Thank you.
---- source code ----
private boolean initializeRecorder() {
Log.i(TAG, "initializeRecorder");
try {
releaseMediaRecorder();
mRecorder = new MediaRecorder();
mRecorder.setCamera(mCameraDevice);
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setMaxDuration(30000);
mRecorder.setOutputFile("/sdcard/sample.3gp");
mRecorder.setVideoFrameRate(10);
mRecorder.setVideoSize(176, 144);
mRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());
mRecorder.setMaxFileSize(50000000);
mRecorder.prepare(); // <-
occur exception
Log.i(TAG, "initializeRecorder prepared"); // <- not called
return true;
} catch (IllegalStateException e) {
releaseMediaRecorder();
e.printStackTrace();
} catch (IOException e) {
releaseMediaRecorder();
e.printStackTrace();
}
return false;
}
