# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        ffmpeg
# Descr:      software to record, convert and stream audio and video
# URL:        http://ffmpeg.mplayerhq.hu/
# Needs:     
# Changelog:
# 20070519-1: 19/May/2007 by Eric Hameleers <alien@slackware.com>
#             * Initial build.
#               Note that the version is set to the current date
#               (using `date +%Y%d%m` output) when you build ffmpeg
#               from source using this SlackBuild.
#               You can override this behaviour by prepending a specific
#               value for VERSION to the build command, like so:
#               VERSION=20070519 ./ffmpeg.SlackBuild
# 20070612-1: 12/jun/2007 by Eric Hameleers <alien@slackware.com>
#             * Update. Also, make sure that the script actually works
#               for newer snapshots if they should be downloaded.
# 
# Run 'sh ffmpeg.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.

# -- PATENT ALERT! --
# FFmpeg can be built with MP3 audio decoder and AMR video decoder
# (needed for FLV videos) but these libraries are 'contaminated' with
# patents from Fraunhofer and GGP.
# You can build these patended algorithms into ffmpeg, and if you are an
# ordinary end user, no one will bother you for using them.
# For the binaries based on this SlackBuild that I distribute, it is a
# different story. I am not allowed to distribute binary packages that
# incorporate patented code. So here you go. My Slackware package was built
# with "USE_PATENTS=NO" i.e. without using the lame mp3 libary and without the
# AMR libraries.
