-Frame-by-frame MD5 Checksum
-===========================
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ INTRODUCTION
-This example builds upon the simple decoder loop to show how checksums
-of the decoded output can be generated. These are used for validating
-decoder implementations against the reference implementation, for example.

-MD5 algorithm
--------------
-The Message-Digest 5 (MD5) is a well known hash function. We have provided
-an implementation derived from the RSA Data Security, Inc. MD5 Message-Digest
-Algorithm for your use. Our implmentation only changes the interface of this
-reference code. You must include the `md5_utils.h` header for access to these
-functions.

-Processing The Decoded Data
----------------------------
-Each row of the image is passed to the MD5 accumulator. First the Y plane
-is processed, then U, then V. It is important to honor the image's `stride`
-values.
