161 compressed image is loaded to the end of the output buffer, and
162 trades lower compression ratios for much faster decompression.

164 NOTE: This implements the release version of the LZ4 frame
165 format as generated by default by the 'lz4' command line tool.
166 This is not the same as the outdated, less efficient legacy
167 frame format currently (2015) implemented in the Linux kernel
168 (generated by 'lz4 -l'). The two formats are incompatible.
