^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 209) 	data in form of an array of offsets to the UYVY data blocks. The

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 212) 	UYVY image. Each entry is a 4-byte unsigned integer in big endian
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 213) 	order and it's an offset to a single pixel line of the UYVY image.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 214) 	The first plane can start either with JPEG or UYVY data chunk. The

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 221) 	followed by a 4-byte value indicating size of the pointer array.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 222) 	All numbers in the second plane are also in big endian order.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 225) 	array, which can be different for each frame. The size of the

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 228) 	In order to extract UYVY and JPEG frames an application can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 229) 	initially set a data pointer to the start of first plane and then
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 230) 	add an offset from the first entry of the pointers table. Such a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 231) 	pointer indicates start of an UYVY image pixel line. Whole UYVY
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 232) 	line can be copied to a separate buffer. These steps should be
