自己录制视频失败
自己找了一份简单的录制视频的app程序，在自己的手机上是测试好用的，可以正常录制，但在E9这个平板电脑上不能录制，出现异常。现在的问题显示是在调用MediaRecorder这个类中prepare()这个方法时发生异常。下面将参录制视频的程序以及app运行以后的日志文件信息附上，希望知道的大神能给小弟解答下，谢谢！videoFile = new File(Environment
.getExternalStorageDirectory()
.getCanonicalFile() + "/testvideo.3gp");mRecorder = new MediaRecorder();
mRecorder.reset();mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);mRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mRecorder.setVideoSize(1280, 720);mRecorder.setVideoFrameRate(20);
mRecorder.setOutputFile(videoFile.getAbsolutePath());mRecorder.setPreviewDisplay(sView.getHolder().getSurface()); mRecorder.prepare();mRecorder.start();
