Hi,
I am trying to run MediaRecorder code snippet from Develope's
documentation, on emulator at this time:
try {
MediaRecorder recorder = new
MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); - doesn't
work at all
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.setOutputFile("/sdcard/cap");
recorder.setVideoSize(176, 144);
recorder.setVideoFrameRate(10);
//recorder.setPreviewDisplay(surfaceHolder.getSurface());
//panelPreview.setVisibility(LinearLayout.VISIBLE);
recorder.prepare();
recorder.start();
}
catch (Exception e)
{
Log.d("!! EXCEPTION: ", e.getMessage());
}
i have the following errors on "recorder.prepare()" :
02-06 09:46:56.879: WARN/MediaProfiles(34): could not find media config xml file
02-06 09:46:57.599: ERROR/CameraInput(34): Unsupported

02-06 09:47:01.929: ERROR/MediaRecorder(282): prepare failed: -1
What is "media config xml " file - do i need special config file for
MediaRecorder ? docs don't mention it?
What is the meaning of "No surface is available for display" error message?
Thank you,
-V
