FFmpeg is a complete solution to record, convert and stream audio and video. It includes libavcodec, the leading audio/video codec library. You can enable a lot of optional (not-autodetected) features by passing variables to the script (VAR=yes/no ./ffmpeg.SlackBuild): DC1394=yes|no (default: no), requires libdc1394 DIRAC=yes|no (default: no), requires dirac FAAC=yes|no (default: no), requires faac (creates non-redistributable binary) FAAD=yes|no (default: no), requires faad2 GSM=yes|no (default: no), requires gsm JP2=yes|no (default: no), requires openjpeg LAME=yes|no (default: yes), requires lame OPENCORE=yes|no (default: no), requires opencore-amr RTMP=yes|no (default: no), requires rtmpdump SCHROEDINGER=yes|no (default: no), requires schroedinger SPEEX=yes|no (default: no), requires speex VPX=yes|no (default: no), requires libvpx X264=yes|no (default: yes), requires x264 XVID=yes|no (default: no), requires xvidcore Make sure to run this script in a real root shell ("su -") and that you have either tetex or texlive installed. All of the mentioned requirements are available from SlackBuilds.org
