android - MediaRecorder.stop() stop failed: -1007

I am recording video with MediaRecorder. My code works fine on 2.3.3 but fails on 4.0.3.

The issue is following: the code mediaRecorder.stop() throws the RuntimeExeption

java.lang.RuntimeException: stop failed.
    at android.media.MediaRecorder.stop(Native Method)

with LogCat message

04-05 15:10:51.815: E/MediaRecorder(15709): stop failed: -1007

UPDATE

I've found, that MediaPlayer reports an error (via MediaPlayer.OnErrorListener) almost immediately after the start. Error code is 100 (media server died), extra -1007.

UPDATE 2 Code to prepare the MediaRecorder

            c = Camera.open();

    ...

    // Step 1: Unlock and set camera to MediaRecorder
    camera.unlock();
    mediaRecorder.setCamera(camera);

    // Step 2: Set sources
    mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
    mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

    // Step 3: Set a CamcorderProfile (requires API Level 8 or higher)
    CamcorderProfile profile = CamcorderProfile
            .get(CamcorderProfile.QUALITY_HIGH);

    // manual set up!

    mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);

    mediaRecorder.setVideoEncodingBitRate(profile.videoBitRate);
    mediaRecorder.setVideoFrameRate(profile.videoFrameRate);
    mediaRecorder.setVideoSize(profile.videoFrameWidth,
            profile.videoFrameHeight);

    mediaRecorder.setAudioChannels(profile.audioChannels);
    mediaRecorder.setAudioEncodingBitRate(profile.audioBitRate);
    mediaRecorder.setAudioSamplingRate(profile.audioSampleRate);

    mediaRecorder.setAudioEncoder(profile.audioCodec);
    //mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
    mediaRecorder.setVideoEncoder(profile.videoCodec);

    // mediaRecorder.setProfile(profile);

    // Step 4: Set output file
    mediaRecorder.setOutputFile("somefile.mp4");

    // Step 5: Set the preview output
    mediaRecorder.setPreviewDisplay(preview.getHolder().getSurface());

    // Step 6: Prepare configured MediaRecorder
    try {
        mediaRecorder.prepare();
    } catch ...
    { release mediaRecorder}

then I simplyCall mediaRecorder.start() please note, that I need video to be encoded into mp4 format. This code works on Samsng Galaxy GIO (android 2.3.3) and fails as described on Acer E305 (android 4.0.2)

Any ideas? Thanks.

Solved it at last. The issue was setting the preview size before setting the actual preview for the camera. The preview size MUST be equal to the selected video size.

CamcorderProfile profile = [get required profile];

Camera.Parameters parameters = mCamera.getParameters();
parameters.setPreviewSize(profile.videoFrameWidth,profile.videoFrameHeight);
mCamera.setParameters(parameters);

mCamera.setPreviewDisplay([surface holder]);
mCamera.startPreview();

...

//configure MediaRecorder and call MediaRecorder.start()
