FFMPEG libx264解码为YUV

FFMPEG libx264解码为YUV

在​​FFMPEG​​中，图像原始数据包括两种：planar和packed。planar就是将几个分量分开存，比如YUV420中，data[0]专门存Y，data[1]专门存U，data[2]专门存V。而packed则是打包存，所有数据都存在data[0]中

具体哪个格式是planar，哪个格式是packed，可以查看pixfmt.h文件，路径为ffmpeg/libavutil/pixfmt.h。注：有些格式名称后面是LE或BE，分别对应little-endian或big-endian。另外名字后面有P的是planar格式。
