# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        handbrake
# Descr:      video transcoder and ripper
# URL:        http://handbrake.fr/
# Build needs:(Slackware 14.2 only):
#             meson, python3, python3-setuptools, gcc >= 7, clang >= 8,
#             nasm >= 2.13.02, cmake >= 3.16.3.
# Needs:      vlc or libdvdcss (to read encrypted DVD's)
# Changelog:  
# r2606-1:    23/Jun/2009 by Eric Hameleers, Eindhoven, NL
#             * Initial build.
#                Note, that handbrake will download a lot of other dependencies
#                on it's own, so it will require an Internet connection during
#                compilation.
# r2830-1:    20/sep/2009 by Eric Hameleers <alien@slackware.com>
#             * Update.

# 0.9.5-1:    04/jan/2011 by Eric Hameleers <alien@slackware.com>
#             * Finally, a new release. Also, make it show an icon in the
#               XFCE menu. This package no longer depends on webkitgtk.

# -- PATENT ALERT! --
# The ffmpeg in HandBrake can be built with AAC audio encoder (used in MP4)
# but this library is 'contaminated' with patents from Apple etc.
# In addition, the FDK AAC encoder has a GPL-imcompatible license so
# ffmpeg forbids redistribution of binaries containing that encoder.
# 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 aac libs.
