Comment:

 Your jpgs produce a fine mpg for me with ffmpeg -i sxi_00%2d.jpg out.mpg
 and I get no decoding errors.

 Please test a supported version of FFmpeg, that is either latest git
 (preferred) or 0.7.1 (the version you tested is much older) or 0.8.
 Please try to avoid --extra-cflags if compilation succeeds without them,
 if you believe some of them make sense, please report so they can be added
 automatically.

 (Irrelevant stack alignment warning cut.)

 (I did not test x264 output, but I assume some defaults changed if the
 quality seems worse to you compared to older versions of FFmpeg and x264.)
