OFFSET
Video U Even Buffer Start Offset. This value represents the starting location for Video
U Buffer for even fields when interlacing is enabled (DC Memory Offset 094h[11] = 1)
and YUV 4:2:0 mode is selected (DC Memory Offset 004h[20] = 1). The lower five bits
should always be programmed as zero so that the start offset is aligned to a 32-byte
boundary.
