	<flag name="3dnowext">
		Enable manually-optimised routines using the AMD 3DNow!Ex SIMD
		instruction set, present in modern AMD CPUs.  (Check for
		3dnowext in /proc/cpuinfo to know whether your CPU supports it).
	</flag>
	<flag name="aac">Use external vo-aacenc library for AAC encoding</flag>
	<flag name="amr">Enable Adaptive Multi-Rate Audio support</flag>
	<flag name="avx">Adds support for Advanced Vector Extensions instructions (Intel Sandy Bridge, AMD Bulldozer and later chips)</flag>
	<flag name="cdio">Enable audio CD grabbing with <pkg>dev-libs/libcdio</pkg>.</flag>
	<flag name="cpudetection">Enables runtime CPU detection (useful for bindist, compatibility on other CPUs).</flag>
	<flag name="dirac">Enable Dirac video support (an advanced royalty-free video compression format) via the reference library: dirac.</flag>
	<flag name="faac">Use external faac library for AAC encoding</flag>
	<flag name="fdk">Use external fdk-aac library for AAC encoding</flag>
	<flag name="frei0r">Enable frei0r wrapping in libavfilter</flag>
	<flag name="gpl">Build all GPL licensed code. Without this flag set the package is build under LGPL license.</flag>
	<flag name="hardcoded-tables">Use pre-calculated tables rather than calculating them on the fly.</flag>
	<flag name="mmxext">Enable mmx2 support.</flag>
	<flag name="network">Enable network streaming support.</flag>
	<flag name="openssl">Prefer <pkg>dev-libs/openssl</pkg> over <pkg>net-libs/gnutls</pkg> to provide SSL/TLS support (notice: the resulting binaries are unredistributable).</flag>
	<flag name="pulseaudio">Enable pulseaudio input support.</flag>
	<flag name="pic">Force shared libraries to be built as PIC (this is slower).</flag>
	<flag name="qt-faststart">Build and install qt-faststart application.</flag>
	<flag name="rtmp">Enable Real Time Messaging Protocol using librtmp instead the native implementation.</flag>
	<flag name="schroedinger">Enable Dirac video support (an advanced royalty-free video compression format) via libschroedinger (high-speed implementation in C of the Dirac codec).</flag>
	<flag name="ssl">Enable SSL/TLS support using <pkg>dev-libs/openssl</pkg> or <pkg>dev-libs/gnutls</pkg>.</flag>
	<flag name="ssse3">faster floating point optimization for SSSE3 capable chips (Intel Core 2 and later chips).</flag>
	<flag name="tools">Build and install small tools like aviocat, cws2fws, graph2dot, ismindex, qt-faststart.</flag>
	<flag name="vaapi">Enable VAAPI (Video Acceleration API) for hardware decoding.</flag>
	<flag name="vis"> Adds support for SIMD optimizations for UltraSPARC processors.</flag>
	<flag name="vpx">Enable vp8 encoding support using libvpx.</flag>
