88 * This range is reserved for pixel formats that are specific to the HAL
89 * implementation. Implementations can use any value in this range to
90 * communicate video pixel formats between their HAL modules. These formats
91 * must not have an alpha channel. Additionally, an EGLimage created from a
92 * gralloc buffer of one of these formats must be supported for use with the
93 * GL_OES_EGL_image_external OpenGL ES extension.
99 * This format is exposed outside of the HAL to software decoders and
100 * applications. EGLImageKHR must support it in conjunction with the
101 * OES_EGL_image_external extension.
103 * YV12 is a 4:2:0 YCrCb planar format comprised of a WxH Y plane followed
104 * by (W/2) x (H/2) Cr and Cb planes.
106 * This format assumes
109 * - a horizontal stride multiple of 16 pixels
110 * - a vertical stride equal to the height
112 * y_size = stride * height
113 * c_size = ALIGN(stride/2, 16) * height/2
114 * size = y_size + c_size * 2
116 * cb_offset = y_size + c_size
