Because LZ4 doesn't define a container format, the python bindings will insert the original data size as an integer at the start of the compressed payload, like most bindings do anyway (Java...)
No pressure here, just willing to note that this sentence is no longer true : there is now a container format defined for file or stream compression : http://fastcompression.blogspot.fr/2013/04/lz4-streaming-format-final.html
(It's also present into root directory of SVN directory).
All LZ4 versions are invited to support a common format in order to improve compatibility between versions.
Best Regards
