# 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.
# 20071006-1: 06/oct/2007 by Eric Hameleers <alien@slackware.com>
#             * Update. Added documentation of the included libraries.
# 20071209-1: 09/dec/2007 by Eric Hameleers <alien@slackware.com>
#             * Update of ffmpeg snapshot plus several of the support libs.
#               Re-added AMR libraries, added libgsm and 1394 (firewire)
#               support, and messed up the SlackBuild script pretty good.
#               Added a download function for checking out SVN/CVS snapshots,
#               which can easily be expanded for multiple snapshots.
# 20080303-1: 03/mar/2008 by Eric Hameleers <alien@slackware.com>
#             * Update of ffmpeg and x264 snapshots to their latest versions.
#               Added dirac codec support. Internally use variable FFMPEG
#               instead of VERSION to determine the version of ffmpeg to use
#               (allows me to use a SVN revision number instead of timestamp).
# r14080-1:   05/aug/2008 by Eric Hameleers <alien@slackware.com>
#             * Update of almost all composing libraries. The dirac reference
#               implementation library was replaced by schroedinger.
#               This version of the package includes shared libraries which
#               allows other programs to link to avcodec.
#               If you install yasm, the SlackBuild will be able to use a
#               very recent version of the x264 library, else it will fallback
#               to a version that compiles with Slackware's 'asm'.
# r16039-1:   09/dec/2008 by Eric Hameleers <alien@slackware.com>
#             * Updated to the 20081209 snapshot. Also updated x264 and lame
#               codecs, removed liba52 (because ffmpeg now has it's own native
#               implementation) and added speex codec.
#               
# Run 'sh ffmpeg.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'. 
#
# -----------------------------------------------------------------------------

# Set initial variables:

# -- PATENT ALERT! --
# FFmpeg can be built with MP3 audio encoder (needed for FLV videos),
# AMR audio encoder (needed for 3GGP videos) and AAC audio encoder (used in MP4)
# but these libraries are 'contaminated' with patents from Fraunhofer, GGP etc.
# 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 and aac libs and
# without the AMR libraries.
#USE_PATENTS="NO"
USE_PATENTS=${USE_PATENTS:-"YES"}

# If you set REQUIRE_YASM to "NO" then the script won't refuse to build
# ffmpeg in case you don't have yasm installed (it is needed to build x264
# newer than the 20080301 snapshot). In this case, the script will
# automatically 'downgrade' x264 to the 20080301-2245 snapshot.
