Remarks

Android YUV format.

This format is exposed to software decoders and applications.

YV12 is a 4:2:0 YCrCb planar format comprised of a WxH Y plane followed by (W/2) x (H/2) Cr and Cb planes.

This format assumes <ul> <li>an even width</li> <li>an even height</li> <li>a horizontal stride multiple of 16 pixels</li> <li>a vertical stride equal to the height</li> </ul>

y_size = stride * height
            c_stride = ALIGN(stride/2, 16)
            c_size = c_stride * height/2
            size = y_size + c_size * 2
            cr_offset = y_size
            cb_offset = y_size + c_size

For the android.hardware.camera2 API, the #YUV_420_888 format is recommended for YUV output instead.

For the older camera API, this format is guaranteed to be supported for android.hardware.Camera preview images since API level 12; for earlier API versions, check android.hardware.Camera.Parameters#getSupportedPreviewFormats().

Note that for camera preview callback use (see android.hardware.Camera#setPreviewCallback), the <var>stride</var> value is the smallest possible; that is, it is equal to:

stride = ALIGN(width, 16)
