解决方法

    recorder.SetCamera (_camera);

    recorder.SetAudioSource (AudioSource.Mic);    
    recorder.SetVideoSource (VideoSource.Camera); 

    recorder.SetoutputFormat (OutputFormat.Default);

    recorder.SetAudioEncoder (AudioEncoder.Default);
    recorder.SetVideoEncoder (VideoEncoder.Default);

    //CamcorderProfile p = CamcorderProfile.Get(0,CamcorderQuality.High);
    //recorder.SetProfile(p);

    recorder.SetoutputFile (path);       

    recorder.SetPreviewdisplay(video.Holder.Surface);
