推流yasea遇到问题，即调转摄像头算法

在build文件删掉ndk
把minsdk改为16

调转摄像头SrsView方法中
修改
public void setPreviewOrientation(int orientation) {
mPreviewOrientation = orientation;
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(mCamId, info);
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
mPreviewRotation = info.orientation % 360;
mPreviewRotation = (360 - mPreviewRotation) % 360; // compensate the mirror
} else {
mPreviewRotation = (info.orientation + 360) % 360;
}
} else if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
mPreviewRotation = (info.orientation + 90) % 360;
mPreviewRotation = (360 - mPreviewRotation) % 360; // compensate the mirror
} else {
mPreviewRotation = (info.orientation + 270) % 360;
}
}
}
