Error when passing the -qcomp parameter with the libx264 video codec

GoogleCodeExporter commented 8 years ago

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

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

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.
