230 [3] If an application attempts to decompress a Huffman-coded JPEG image whose
231 header does not contain Huffman tables, libjpeg-turbo will now insert the
232 default Huffman tables.  In order to save space, many motion JPEG video frames
233 are encoded without the default Huffman tables, so these frames can now be
