录制视频时出现音频问题
我可以录制视频，但没有获得该视频的音频。 谁能帮我同时录制视频和音频。 我的代码如下：
mr = new MediaRecorder();
mr.setAudioSource(MediaRecorder.AudioSource.MIC);
mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mr.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
mr.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mr.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mPreview = new Preview(RecordVideo.this,mr);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
当我放置audioSource和audioEncoder时，它出现运行时错误： 日志猫详细信息是：
05-07 10:17:01.175: ERROR/MediaRecorder(22990): setAudioEncoder called in an invalid state(2)
05-07 10:17:01.175: ERROR/AndroidRuntime(22990): at android.media.MediaRecorder.setAudioEncoder(Native Method)
当我从代码中删除这些audioSource和audioEncoder时，它对于没有音频的视频工作正常。 我还需要音频和视频 提前致谢：
I am able to record video but I am not getting audio for that video.
Can any one help me to record video&audio at same time.
my code is as follows:
mr = new MediaRecorder();
mr.setAudioSource(MediaRecorder.AudioSource.MIC);
mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mr.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
mr.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mr.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
mPreview = new Preview(RecordVideo.this,mr);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
when I put audioSource and audioEncoder its getting runtime error:
log cat details are:
05-07 10:17:01.175: ERROR/MediaRecorder(22990): setAudioEncoder called in an invalid state(2)
05-07 10:17:01.175: ERROR/AndroidRuntime(22990): at android.media.MediaRecorder.setAudioEncoder(Native Method)
when I remove those audioSource and audioEncoder from code its working fine for video without audio.
I need to have audio also with video
thanks in advance:

您应该在
setOutputFormat()之后调用setAudioEncoder()。You should call
setAudioEncoder()aftersetOutputFormat().
