i tried lot of instruction to install ffmpeg on ubuntu...
all them were failed it returns finally...
libfaac is nonfree and --enable-nonfree is not specified.
If you think configure made a mistake, make sure you are using the latest
version from SVN. If the latest version fails, report the problem to the
email@example.com mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
what i need to do..
