**************************************************************************************
**************************************************************************************
This file is targeted at newbies who are unfamiliar with what to do after obtaining the 
X264 encoder source from videolan.org

Options may have to be changed as needed for a particular situation.

This is basically summarized from the threads in the topic
"VLC x264 GCC profiling" under [Home » All forums » OC H.264 project]


System    : Atom N270 (1.6 GHz) with 1GB DDR2 (667 MHz) running Ubuntu Netbook Remix
 
**************************************************************************************
**************************************************************************************

STEP 1 of 5:

To get all the x264 files:
test $ git clone git://git.videolan.org/x264.git

**************************************************************************************

STEP 2 of 5: Setup for enabling profiling, debug 

test $ ./configure --disable-avis-input --disable-mp4-output --disable-pthread --enable-debug --enable-gprof

Platform:   X86
System:     LINUX
asm:        yes
avis input: no
mp4 output: no
pthread:    no
debug:      yes
gprof:      yes
PIC:        no
shared:     no
visualize:  no

You can run 'make' or 'make fprofiled' now.

STEP 3 of 5: Run the make script to build 

test $ make -f Makefile
