카메라가 setVideoSize()를 지원하지 않습니다.

Question

동영상을 녹화하고 재생하려고합니다.

동영상 녹화를 시작할 때 많은 기기가 폭주하는 것을 보았습니다.

logcat에서 문제가 비디오의 크기라는 것을 깨달았습니다.

카메라보기가 작고, 몇 픽셀 정도가 문제입니까?

수정해야 할 사항은 무엇입니까? 방법?

     mMediaRecorder = new MediaRecorder();

Answer 1

CamcorderProfile.get(int) 기본 (후면) 카메라의 프로파일을 반환합니다. mCamera가 전면 카메라 인 경우 적절한 카메라 ID와 함께 CamcorderProfile.get(int, int)을 사용해야합니다.

Answer 2

/** Camera 객체의 인스턴스를 안전하게 가져 오는 방법입니다. */

public Camera getCameraInstance() { 
    Camera c = null; 
    try { 
     c = Camera.open(Camera.getNumberOfCameras() - 1); 
    } catch (Exception e) { 
     e.printStackTrace(); 
     onError(); 
    } 
    return c; 
}
