    ffmpeg installation: opus not found

    I am trying to install ffmpeg via:
    Code:
    ./configure --prefix="$HOME/ffmpeg_build" \
      --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
      --bindir="$HOME/bin" --extra-libs="-ldl" --enable-gpl --enable-libass --enable-libfdk-aac \
      --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx \
      --enable-libx264 --enable-nonfree --enable-x11grab
    I am getting error:
    Code:
    ERROR: opus not found
    I have aslo installed libopus using http://ffmpeg.org/trac/ffmpeg/wiki/U...mpilationGuide
    and successfully installed it using :
    Code:

    tar xzvf opus-1.0.3.tar.gz
    cd opus-1.0.3
    ./configure --prefix="$HOME/ffmpeg_build" --disable-shared
    make
    make install
    make distclean

    libopus.a
    libopus.la

    the problem has been solved. I contacted the IRC channel #ffmpeg.
    had to reset the PKG_CONFIG_PATH environment variable to opus.pc directory

    I went through the guide on 12.04 and did not experience the same issue and the following command from the guide should have done what you needed:

    Code:
    PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"

    the command needed to be modified a bit to work.
    Earlier i used it,but couldn't work(error: opus not found) but the i used:
    Code:
    PKG_CONFIG_PATH="/home/ffmpeg_build/lib/pkgconfig"
    and everything worked.
    I don't know,both are same although

    "$HOME" and "/home" are different:

    Code:
    $ echo $HOME
    /home/prkhr4u
    $HOME is an environment variable and refers to the home directory of the user, while /home is just the /home directory.
