请问如何添加背景音乐呢？
ffmpeg能添加自己编译出来的库来支持x86吗

以下是我调整比例的代码，发现需要调用两次才能重置视频预览。
请大佬指点一下。感谢！
bz_camera2_view.setPreviewTargetSize(480, 480);
ViewGroup.LayoutParams params = bz_camera2_view.getLayoutParams();
params.height = ScreenUtils.getWidthPixels(RecordActivity.this);
bz_camera2_view.setLayoutParams(params);
bz_camera2_view.startPreview();

横屏下手动调用 switchCamera2ID( ) 后预览旋转了90度, 设置旋转90度 也只是预览角度正常，两侧空白的，录制结果还是旋转了90度，该怎么调整呢，Camera 实例貌似也没有api 接口获取

bz_camera_view.switchCamera2ID(getCameraId());
bz_camera_view.setRotation(90f);

请问不是视频的音频文件可以添加背景音乐吗？？
