format11是nv21，format23是YCBCR420_888。为什么两种不同格式的流？

ImageFormat.java

public static final int PRIVATE = 0x22;
public static final int YUV_420_888 = 0x23;
public static final int NV21 = 0x11;

HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED 0x22

HAL_PIXEL_FORMAT_YCbCr_420_888 0x23

YUV_420_888介绍及YUV420转RGBA - 简书

" YUV_420_888是可以兼容所有YUV420P和YUV420SP格式的。也就是说上面提到的I420、YV12、NV12、NV21都可以是YUV_420_888的具体实现。"
