Module: libav Branch: master Commit: 983db9b2b4c753507d1cf8427675fca80d598b4c
Author: Samuel Pitoiset <samuel.pitoi...@gmail.com> Committer: Martin Storsjö <mar...@martin.st> Date: Thu Jul 5 11:19:13 2012 +0200 xtea: Make the count parameter match the documentation Previously it was interpreted as number of bytes, while the documentation stated that it was the number of 8 byte blocks. This makes it behave similarly to the existing AES code.
