[FFmpeg-user] Error On installing FFMPEG-MASTER for opencv

[mohan kannan]

Dear Developer,
                         On configuring FFMPEG-MASTER,it is telling that
,ERROR: libx264 not found.If you think configure made a mistake, make sure
you are using the latest version from Git.  If the latest version fails,
report the problem to the
ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
                           I've tried different method,even installed
newest FFMPEG zip....It is still showing this error..What to do.Please
solve this bug and please send me a solution.
