相机输入:不支持的参数
首先,请原谅它已经被问过或者可以通过谷歌轻松找到。我发布此内容是因为我的时间有限。这是录制音频和视频的代码。
stopPreview();
Log.d("streamer", "Start camera.....");
videoRecorder = new MediaRecorder();
videoRecorder.setPreviewDisplay(surfaceView.getHolder()
.getSurface());
videoRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
videoRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
videoRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
videoRecorder.setVideoSize(800, 600);
videoRecorder.setVideoFrameRate(30);
videoRecorder.setOutputFile(videoPipe.getOutput());
videoRecorder.prepare();
videoRecorder.start();
Log.d("streamer", "Start camera.....action.......");
Log.d("streamer", "Start mic.....");
audioRecorder = new MediaRecorder();
audioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
audioRecorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
audioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
audioRecorder.setOutputFile(audioPipe.getOutput());
audioRecorder.prepare();
audioRecorder.start();
Log.d("streamer", "Start mic.....action");
但是,当我运行它时,上面的代码在 logcat 上生成以下内容。
12-22 09:05:43.456: E/CameraInput(2407): Unsupported parameter(x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value)

12-22 09:05:43.464: E/MediaProfiles(2407): mCodec : 3
并且,显示预览的表面视图似乎被冻结了。它显示最后拍摄的图像帧。此外,视频和音频似乎没有录制。会出现什么问题呢?非常感谢任何帮助!
注意:
我正在运行 Android 2.2 的 Samsung Galaxy Tab 上尝试此操作。
注释以下两行似乎也不能解决问题
videoRecorder.setVideoSize(800, 600);
videoRecorder.setVideoFrameRate(30);
以下权限是在清单文件上设置的。
<uses-permission android:name="android.permission.CAMERA"></uses-permission>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
Firstly, please forgive it is already asked one or can be find easily with Google. I am posting this since I do have only limited time. Here is code to record audio and video.
stopPreview();
Log.d("streamer", "Start camera.....");
videoRecorder = new MediaRecorder();
videoRecorder.setPreviewDisplay(surfaceView.getHolder()
.getSurface());
videoRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
videoRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
videoRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
videoRecorder.setVideoSize(800, 600);
videoRecorder.setVideoFrameRate(30);
videoRecorder.setOutputFile(videoPipe.getOutput());
videoRecorder.prepare();
videoRecorder.start();
Log.d("streamer", "Start camera.....action.......");
Log.d("streamer", "Start mic.....");
audioRecorder = new MediaRecorder();
audioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
audioRecorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
audioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
audioRecorder.setOutputFile(audioPipe.getOutput());
audioRecorder.prepare();
audioRecorder.start();
Log.d("streamer", "Start mic.....action");
But, when I run it, the above code produces the following on logcat.
12-22 09:05:43.456: E/CameraInput(2407): Unsupported parameter(x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value)

And, the surface view showing preview seems to be freezed. It shows last taken frame of image. Also, the video & audio doesn't seems to be recording. What will be the problem? Any help is very much appreciated!
NOTE:
I am trying this on Samsung Galaxy Tab with Android 2.2.
Commenting the following two lines also doesn't seems to solve the problem
videoRecorder.setVideoSize(800, 600);
videoRecorder.setVideoFrameRate(30);
The following permissions are set on the manifest file.
<uses-permission android:name="android.permission.CAMERA"></uses-permission>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO"/>

如果您看到 MPEG-4 SP 的支持的媒体格式,您需要使用 3GP (
THREE_GPP
) 输出格式。所以你可以尝试
