# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        ffmpeg3-compat
# Descr:      software to record, convert and stream audio and video
# URL:        http://ffmpeg.org/
# Needs:      
# Changelog:
# 3.4.6-1:    30/mar/2019 by Eric Hameleers <alien@slackware.com>
#             * Created (re-using my ffmpeg.SlackBuild script).
#               This package only contains ffmpeg3 libraries, and no
#               programs, headers or configuration files.
#               
# Run 'sh ffmpeg3-compat.SlackBuild' to build a Slackware package.
# The package (.txz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.

# -- PATENT ALERT! --
# FFmpeg can be built with AAC audio encoder (used in MP4) but this library is
# 'contaminated' with patents from 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 aac libs.
USE_PATENTS=${USE_PATENTS:-"NO"}

# I don't care if the user says "no" or "NO":
USE_PATENTS=$(echo $USE_PATENTS | tr 'a-z' 'A-Z')

#
# == 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)
