Raspberry Pi: How to compile OpenMAX and FFMPEG on RPi
In order to use the RPi's hardware video acceleration, you need the OpenMAX libs. Here's how to compile and make a Slackware package-
=====Build OpenMAX Slackware Package=====
Get the following two files (from the Debian/Ubuntu package repositories):
libomxil-bellagio-0.9.3.tar.gz
libomxil-bellagio_0.9.3-4.debian.tar.xz
Code:
mkdir /tmp/build
rm -rf /tmp/build/*
tar -xvzf libomxil-bellagio-0.9.3.tar.gz
tar -xf libomxil-bellagio_0.9.3-4.debian.tar.xz
cd libomxil-bellagio-0.9.3
./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc
patch -p1 < ../debian/patches/0001-Fallback-on-different-registry-location-except-for.patch
patch -p1 < ../debian/patches/0002[hit TAB]
patch -p1 < ../debian/patches/0003[hit TAB]
patch -p1 < ../debian/patches/0004[hit TAB]
patch -p1 < ../debian/patches/0005[hit TAB]
patch -p1 < ../debian/patches/0006[hit TAB]
patch -p1 < ../debian/patches/0007[hit TAB]

OpenMAX Bellagio: OpenMAX Bellagio (API to access Multimedia Components)
OpenMAX Bellagio:
OpenMAX Bellagio: OpenMAX Integration Layer (IL) is a standard API to access Multimedia
OpenMAX Bellagio: Components on mobile platforms. It has been defined by the Khronos
OpenMAX Bellagio: group. By means of the OpenMAX IL API, multimedia frameworks can
OpenMAX Bellagio: access hardware accelerators on platforms that provide it.
OpenMAX Bellagio:
OpenMAX Bellagio: Bellagio is an opensource implementation of the OpenMAX IL API that
OpenMAX Bellagio: runs on Linux PC.

cd /tmp/build
makepkg ../libomxil-bellagio-0.9.3-armv7l-ARG.tgz
installpkg /tmp/libomxil-bellagio-0.9.3-armv7l-ARG.tgz
=====Build FFMPEG Slackware Package=====
Download and uncompress the ffmpeg source files
Code:
rm -rf /tmp/build/*
cd FFmpeg/
./configure --prefix=/usr --libdir=/usr/lib --shlibdir=/usr/lib --mandir=/usr/man --arch=armel --target-os=linux --enable-gpl --enable-omx
make
make install DESTDIR=/tmp/build
strip -s /tmp/build/usr/lib/* /tmp/build/usr/bin/*
gzip -9 /tmp/build/usr/man/man?/*.?
cd /tmp/build; mkdir install; cd install
