I'm new to video compression; but I see many of the terms repeated over and over again. I'm wondering what's the difference between x.264 and libx264 and H.264?

H.264 is video encoding method, an alias name for MPEG-4 AVC compression, also known as MPEG-4 Part 10, defined in joint ISO/IC and ITU specification "Information technology — Coding of audio-visual objects — Part 10: Advanced Video Coding".
The specification is freely available here: http://www.itu.int/rec/T-REC-H.264-201304-I/en
x264 is a library implementing video compression and producing H.264 compatible stream.
