API 21引入了Camera2,deprecated掉了Camera,确立Image作为相机得到的原始帧数据的载体;硬件编解码的MediaCodec类加入了对Image和Image的封装ImageReader的全面支持。可以预见,Image将会用来统一Android内部混乱的中间图片数据(这里中间图片数据指如各式YUV格式数据,在处理过程中产生和销毁)管理。 本文主要介绍YUV_420_888格式的...
Android: convert YUV_420_888 image format Image to YUV420Planar (I420) and YUV420SemiPlanar (NV21) color format byte array (raw file). 背景 代码思路来自Android CTS,出处见参考 从Android SDK 21开始,Android就开始推行新的原始(未压缩)图片数据的载体类Image,和新的YUV格式YUV420Flexible,配套YUV_420...

The order of planes in the array returned byandroid.media.Image#getPlanes() Image#getPlanes()is guaranteed such that plane #0 is always Y, plane #1 is always U (Cb), and plane #2 is always V (Cr). In contrast to the#YUV_420_888format, the Y-plane may have a pixel stride greater...

在Android Camera中文档中强烈推荐使用NV21和YV12,因为这两种格式支持所有的相机设备。Camera默认输出YUV的数据格式为NV21。但是在Camera2中,推荐使用的格式则是YUV_420_888。 ImageFormat.NV21 注释 YCrCb format used for images, which uses the NV21 encoding format. ...
