x264 is an open-source H.264 encoder (http://developers.videolan.org/x264.html)
(and H.264 is also known as MPEG-4 AVC, a very high compression video codec)

mkv is the file extension of "matroska" multimedia files. The mkv format is
yet another multimedia container format (like .avi, .mov, etc...) which can
accomodate several types of video and audio codecs. It's main advantage is
the ability to store several audio/subtitle tracks in the same file and be
able to switch easily between them, if your player supports them
(http://www.matroska.org/)

So, I figure the original poster was referring to a mkv file containing
the video encoded in the H.264 video format with x264.

Of course, not a lot of players are able to play such files, and this would
probably require a pretty beefy CPU anyway.

Hope this helps,
