Created: /var/tmp/ffmpeg-${FFMPEG_VERSION}-opera-${ARCH}-binaries.tar.gz

To install issue the following as root or with sudo, adjusting the *Install* path as needed (see opera://about):

    tar fx /var/tmp/ffmpeg-${FFMPEG_VERSION}-opera-${ARCH}-binaries.tar.gz -C /usr/lib/${PATHARCH}-linux-gnu/opera

Now restart Opera and you should have working H.264 and MP3 support.
