我有Android 4.0的平板電腦acer a500。setrecVideoSize上的媒體記錄器凍結應用程序
我可以（：176×144目標大小）：錄製視頻
_recorder = new MediaRecorder();
camera.unlock();
_recorder.setCamera(camera);
_recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
_recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
_recorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
_recorder.setOutputFile(outputPath);
_recorder.setPreviewDisplay(surface);
_recorder.prepare();
但我想錄制視頻的改變大小。
旁邊有支持的尺寸：
front

集_recorder.setVideoSize（640，480）_recorder.setOutputFormat後有問題。視頻開始寫入（我看到文件3 kb）和應用程序凍結。我嘗試不同的尺寸。但只能使用兩個：176x144和352x288。
在凍結我看長堆棧：http://bit.ly/Oa5O0D
請幫幫我，怎麼知道的解決方案。
