andrew@skamandros~$ x264 --help | head -n 11
x264 core:68 r1185 2956905
Syntax: x264 [options] -o outfile infile [widthxheight]

Infile can be raw YUV 4:2:0 (in which case resolution is required),
  or YUV4MPEG 4:2:0 (*.y4m),
  or AVI or Avisynth if compiled with AVIS support (no).
Outfile type is selected by filename:
 .264 -> Raw bytestream
 .mkv -> Matroska
 .mp4 -> MP4 if compiled with GPAC support (no)
There has been a problem for some time with with gpac and x264 as can be seen in my own configuration above.

Does this mean that this would be compiling an mp4 encoder to not be able to output to an mp4 container if used on the commandline? If so, how would this be beneficial?

Btw: same output except for yes, which brought in new gpac and new cmake into the mix...
