[poky] XBMC configuration get failed because of libpostproc library from FFMPEG package

[Sparsh Wid hope]

Hi All,

I'm Compiling xbmc-11.1 with the help of poky. But it's getting fail at configure time. 
The OE build configuration is given below:

OE Build Configuration:
BB_VERSION        = "1.11.0"
METADATA_BRANCH   = "bernard-cur"
METADATA_REVISION = "1f2e1abbe2726ea6fc83e83b644ce7ee32a54fa2"
TARGET_ARCH       = "i586"
TARGET_OS         = "linux"
MACHINE           = "fishriver"
DISTRO            = "poky"
DISTRO_VERSION    = "1.0"
TARGET_FPU        = ""

The error log I got is:

checking for FFMPEG... no
| configure: error: Could not find a required library. Please see the README for your platform.
| FATAL: oe_runconf failed
| ERROR: Function 'do_configure' failed (see /home/sct/my_workspace/poky_xbmc_09Mar2012/build/tmp/work/atom-poky-linux/xbmc-11.1-r0/temp/log.do_configure.24741 for further information)
NOTE: package xbmc-11.1-r0: task do_configure: Failed

To find out the reason I looked into config.log  file in xbmc and the information I got is :

configure:23490: checking for FFMPEG
configure:23497: $PKG_CONFIG --exists --print-errors "$FFMPEG_LIBNAMES"
Package libpostproc was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpostproc.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libpostproc' found
configure:23500: $? = 1
configure:23513: $PKG_CONFIG --exists --print-errors "$FFMPEG_LIBNAMES"
Package libpostproc was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpostproc.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libpostproc' found
configure:23516: $? = 1
configure:23529: result: no
No package 'libpostproc' found
configure:23545: error: Could not find a required library. Please see the README for your platform.

I'm using ffmpeg-0.11.1, inside this package I didn't get any libpostproc.pc directory.

I'm unable to understand what is the meaning of this error message and how to resolve it. Please help me to solve the problem.

Thanks in Advance
