android mediarecorder错误(MediaRecorder启动失败:-19) [英] android mediarecorder error (MediaRecorder start failed : -19)

问题描述

当我尝试在程序中制作摄像机时，出现此错误:

E/MediaRecorder:启动失败:-19

代码为

try {
    final SurfaceView sv = (SurfaceView) findViewById(R.id.srvView);
    MediaRecorder mrec = new MediaRecorder();
    mrec.setCamera(camera);

    mrec.setAudioSource(MediaRecorder.AudioSource.MIC);
    mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    mrec.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    mrec.setVideoFrameRate(10);
    mrec.setVideoSize(480, 320);
    mrec.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    mrec.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);

    mrec.setPreviewDisplay(mSh.getSurface());
    mrec.setOutputFile("/mnt/sdcard/pro/andsend.avi");
    mrec.prepare();
    mrec.start();
} catch(Exception e)
{
    e.printStackTrace();
}

我尝试更改顺序并更改设置大小，帧频等...

但是，我找不到问题.

出什么问题了?

解决方案

请参阅我的答案:

I try to change the sequence and change the set size, Frame Rate etc...

But, I can't find the problem.

What's the problem?

解决方案

see my answer : android-mediarecorder-start-failed-19

error code -19 comes about when there is a problem with the size of the video as set by MediaRecorder#setVideoSize()
