using LiveCard as camera preview gives error

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create a LiveCard, with 
liveCard.setDirectRenderingEnabled(true);
liveCard.getSurfaceHolder().addCallback(callback);

2. set up camera recording as per the MediaRecorder tutorial
Camera camera = Camera.open();
// Google Glass workaround, see 
https://code.google.com/p/google-glass-api/issues/detail?id=360#c6
try {
    camera.setPreviewDisplay(null);
} catch (java.io.IOException ioe) {
    Log.d("OR", "IOException nullifying preview display: " + ioe.getMessage());
}
camera.stopPreview();
camera.unlock();
recorder = new MediaRecorder();
recorder.setCamera(camera);
recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
File f = new File(getBaseDir(), getStartTime() + VIDEO_EXTENSION);
recorder.setOutputFile(f.getAbsolutePath());

3. specify the live card as the preview surface:
recorder.setPreviewDisplay(liveCard.getSurfaceHolder().getSurface());

What is the expected output? What do you see instead?
the expected output is that the LiveCard would act as a camera preview surface.

instead, I get the following:

01-22 18:00:14.746: E/SurfaceTextureClient(4656): queueBuffer: error queuing 
buffer to SurfaceTexture, -22
01-22 18:00:14.746: E/SurfaceTextureClient(4656): queueBuffer (handle=0x975198)

What version of the product are you using? On what operating system?
XE12

Please provide any additional information below.

Hello,

Thanks for the report! Could you tell us when you actually start the recording? 
Are you doing this when you create/publish the LiveCard or on a 
DirectRenderingCallback's onSurfaceCreated callback?

For the former case, the SurfaceHolder might not have been created yet which 
would explain the failure.

Best,
Alain
