# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        ffmpeg
# Descr:      software to record, convert and stream audio and video
# URL:        http://ffmpeg.org/
# Needs:      yasm (only compile-time)
# 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.
# r16043-1:   10/dec/2008 by Eric Hameleers <alien@slackware.com>
#             * Update. Also updated libraw1394 & libdc1394 to their 2.x
#               versions and made small adaptations so that the script actually
#               produces working binaries on x86_64
# 0.5-1:      20/mar/2009 by Eric Hameleers <alien@slackware.com>
#             * First new official release in ages. Add x264 presets to the
#               package (idea borrowed from the script at slackbuilds.org).
# 0.5-2:      13/may/2009 by Eric Hameleers <alien@slackware.com>
#             * Updates to faac/faad/schro
# r20056-1:   27/sep/2009 by Eric Hameleers <alien@slackware.com>
#             * Update. AMR implementation from OpenCORE with a free license
#               allows to add AMR support to the distributable package.
#               Also updated the X264 snapshot and libgsm.
# r22900-1:   26/apr/2010 by Eric Hameleers <alien@slackware.com>
#             * New snapshot. Updated the schroedinger codec, which is now
#               on par speed-wise with the dirac codec. Also updated the x264
#               snapshot (x264 can now produce blu-ray compliant video),
#               and updated the lame and dc1394 versions. Added support for
#               RTMP(E) - flash - streams through librtmp.
# r23357-1:   28/may/2010 by Eric Hameleers <alien@slackware.com>
#             * New snapshot. Added libvpx plus patches for ffmpeg which
#               enable support for WebM/VP8 (google-donated new video format).
# 0.6-1:      18/jun/2010 by Eric Hameleers <alien@slackware.com>
#             * A stable release. The internal libvpx library was updated to
#               0.9.1 (no patching needed now), rtmpdump to 2.2e and x264
#               to a recent snapshot.
#               I also added VAAPI hardware acceleration support. Look further
#               down in this script (in the header of the "make_libva" function)
#               how you can benefit from GPU-accelerated encoding/decoding.
# 0.6.1-1:    02/feb/2011 by Eric Hameleers <alien@slackware.com>
#             * I forgot to update to a newer stable release.
#               Updated internal codecs where available.
# 0.6.3-1:    12/may/2011 by Eric Hameleers <alien@slackware.com>
#             * Updated for Slackware 13.37.
# 0.8.2-1:    11/aug/2011 by Eric Hameleers <alien@slackware.com>
#             * Update. Add opencore's new AMR-WB and AAC encoders created
#               for Android by VisualOn: 'libvo-amrwnenc' and 'libvo-aacenc'.
#               And updated every built-in support library to their latest
#               version.
# 0.8.5-1:    07/oct/2011 by Eric Hameleers <alien@slackware.com>
#             * New release. Also updated versions of internal vpx and x264
#               libraries. Fix the compilation in case the x264 libraries are
#               already installed on the system.
# 0.8.6-1:    08/nov/2011 by Eric Hameleers <alien@slackware.com>
#             * New release. Also updated versions of internal lame, orc,
#               x264 libraries.
# 0.8.7-1:    22/nov/2011 by Eric Hameleers <alien@slackware.com>
#             * New release.
# 0.9-1:      13/dec/2011 by Eric Hameleers <alien@slackware.com>
#             * New release.  Added internal libass (subtitle) and v4l2 support.

#             * New release.
# 0.10.3-1:   26/may/2012 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 0.11-1:     03/jun/2012 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 0.11.2-1:   27/sep/2012 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 1.1.2-1:    13/feb/2013 by Eric Hameleers <alien@slackware.com>
#             * Update. Also updated many internal libraries.
#               Added ogg opus decoder.

#               gnutls in the patent-free package).
#               Updated internal libraries: libvpx, x264.

# Install using 'installpkg'.

# -- PATENT ALERT! --
# FFmpeg can be built with MP3 audio encoder (needed for FLV videos) and AAC
# audio encoder (used in MP4) but these libraries are 'contaminated'
# with patents from Fraunhofer, Apple 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 non-free code. So here you go. My Slackware package was built
# with "USE_PATENTS=NO" i.e. without using the lame mp3 and aac libs.
#USE_PATENTS="NO"

# == NOTE ON VAAPI ==
#
# VAAPI can enable hardware accelerated playback for MPEG-2/4, H.264/AVC
# and VC-1 video on certain graphics hardware. 
# The VAAPI support in this ffmeeg package depends on VA drivers that you have
# to install yourself for your specific hardware. The drivers should go into
# directory /usr/lib${LIBDIRSUFFIX}/va/drivers .
# If you install my libva package you can get MPEG-2 hardware acceleration on
# Intel graphics. If you additionally install my vdpau-video package, then you
# get hardware acceleration on Nvidia graphics (with nvidia's binary driver).
# If you own an Ati card and use the fglrx driver, then you can achieve
# hardware acceleration by installing the xvba-video driver from here:
# http://www.splitted-desktop.com/~gbeauchesne/xvba-video/ (since I do not own
# Ati hardware I can not build a package for xvba-video myself)
