This happens with ffmbc 0.6rc6 on Ubuntu 10.04.

  $ ffmbc -v 3 -i trailer_iphone.m4v -vcodec libx264 -qcomp 0.6 trailer.mp4

  FFmbc version 0.6-rc6

  Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

This doesn't seem to be specific to a particular video, I tried it with this 
file: 

  http://mirror.cessen.com/blender.org/peach/trailer/trailer_iphone.m4v

The qcomp option is defined in libx264.c to be of type string, while there's an 
option with the same name and type float in options.c. Removing the line in 
libx264.c fixes the problem.
