我正在尝试使用带有摄像机配置文件480P的媒体记录器录制480X640视频，但在某些设备中，当我按下开始录制时，它会让我开始失败-19。
private void initRecorder() {
if(recorder!=null) return;
// to delete the previous mp4 file created
File deletefile=new File(outputFileName!=null?outputFileName:"abc.mp4");
if(deletefile.exists())
deletefile.delete();
//Create Folder
File folder = new File(Environment.getExternalStorageDirectory()+"/Chance");
if(!folder.exists() )
{
folder.mkdirs();
}
File outFile= new File(folder.toString(),System.currentTimeMillis()+".mp4");
outputFileName= outFile.toString();
System.out.println("Filename "+outputFileName);
if(outFile.exists())
outFile.delete();
try{
//camera.stopPreview();
camera.unlock();
recorder=new MediaRecorder();
recorder.setCamera(camera);
recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
if(typ==1)
{
//sequence should not be change
//Setting the quality of front camera
recorder.setProfile(CamcorderProfile.get(1,CamcorderProfile.QUALITY_480P));
CameraInfo cameraInfo = new CameraInfo();
Camera.getCameraInfo(CameraInfo.CAMERA_FACING_FRONT, cameraInfo);
//To rotate the camera by 630 i.e 90 by default + 270=630
int rot=270;
recorder.setOrientationHint(rot);
}else //video settings for back camera
{
recorder.setProfile(CamcorderProfile.get(0,CamcorderProfile.QUALITY_480P));
recorder.setOrientationHint(camera_orientation);
}
recorder.setMaxDuration(20000); //20 sec
recorder.setPreviewDisplay(holder.getSurface());
recorder.setOutputFile(outputFileName);
recorder.prepare();
Log.v(TAG,"MediaRecorder initilized");
}
catch(Exception e)

@Override

Toast.makeText(getApplicationContext(), "Unable to connect camera", Toast.LENGTH_SHORT).show();

答案 0 :(得分：2)
相机不支持480P那么我应该怎么做才能录制480 X 640
如果相机不支持480p进行视频录制，则无法以480p录制。记录其他一些 支持的分辨率。 QUALITY_LOW和QUALITY_HIGH是唯一可以保证得到支持的人。如果您不喜欢QUALITY_LOW结果，并且QUALITY_480P不可用，请记录QUALITY_HIGH。
