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