+ <entry>Two-planar format used by Samsung S5C73MX cameras. The
+first plane contains interleaved JPEG and UYVY image data, followed by meta data
+in form of an array of offsets to the UYVY data blocks. The actual pointer array
+follows immediately the interleaved JPEG/UYVY data, the number of entries in
+this array equals the height of the UYVY image. Each entry is a 4-byte unsigned
+integer in big endian order and it's an offset to a single pixel line of the
+UYVY image. The first plane can start either with JPEG or UYVY data chunk. The
+size of a single UYVY block equals the UYVY image's width multiplied by 2. The
+size of a JPEG chunk depends on the image and can vary with each line.
+<para>The second plane, at an offset of 4084 bytes, contains a 4-byte offset to
+the pointer array in the first plane. This offset is followed by a 4-byte value
+indicating size of the pointer array. All numbers in the second plane are also
+in big endian order. Remaining data in the second plane is undefined. The
+information in the second plane allows to easily find location of the pointer
+array, which can be different for each frame. The size of the pointer array is
+constant for given UYVY image height.</para>
+<para>In order to extract UYVY and JPEG frames an application can initially set
+a data pointer to the start of first plane and then add an offset from the first
+entry of the pointers table. Such a pointer indicates start of an UYVY image
+pixel line. Whole UYVY line can be copied to a separate buffer. These steps
+should be repeated for each line, i.e. the number of entries in the pointer
+array. Anything what's in between the UYVY lines is JPEG data and should be
+concatenated to form the JPEG stream. </para>
