#
# shamelessly copied from h264enc ;-)
# as I don't have much experience with x264 encoding profiles
# I would like to thank the Author(s) of h264enc.
#
# This is a extra program because I use it in several scripts. 
# I just added interfaces necessary to be called by my scripts. 
# All the gratitude for collecting and supporting the presets belongs to the original author(s) of h264enc. 
# I hope someone else will find this useful.
# 
# The interaction with this script works through output files that are interpreted by the calling script. 
# To see an example how this works, see menc, riptoh264 or blu2mkv scripts.  
#
# Changelog: 
#    06.02.2010 added support for processing geometries and expansion sets depending on input and output geometry,
#                  comparing source video geometry with user or preset specified output video geometries and output 
#                  of mencoder -vf filterchain to scale/expand video if necessary
#               added support to check video bitrate against preset limits
#               fixed a bug where a wrong begin of the optionslist stops encoding
#               fixed a bug that specified vbv_maxrate and vbv_bufsize get overwritten by presets. Now the smaller one is used.
#
