[Linphone-developers] [Vin] Problem with ./configure in 1.5.0

[Vinayak J]

Hi,
  I'm installin Linphone 1.5.0, stable version on Red Hat 9 (Spike),
from the source code. I've installed all the dependencies like
SDL, FFMPEG (RPM)and Lib Theora, SPEEX
All the installations have been successfull. But, when I try to
configure the linphone installation, it gives me the following error.

+++++++++++++++++++++++++++++++++
building from linphone source tree, using ../gsmlib/gsm.h
checking for FFMPEG... Package libavcodec was not found in the
pkg-config search path.
Perhaps you should add the directory containing `libavcodec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libavcodec' found
no
configure: error: Could not find ffmpeg headers and library. This is
mandatory for video support
configure: error: ./configure failed for mediastreamer2

++++++++++++++++++++++++++++++++++

But, my installtions have been successfull and MPLAYER is working
fine.But, linphone is givign me the problem.

Please help me in this regard. 

If possible, please give me the link for rpm's from where I can download
these.
