video media-video@gentoo.org 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). Use external vo-aacenc library for AAC encoding Enable Adaptive Multi-Rate Audio support Adds support for Advanced Vector Extensions instructions (Intel Sandy Bridge, AMD Bulldozer and later chips) Enable audio CD grabbing with dev-libs/libcdio. Enables runtime CPU detection (useful for bindist, compatibility on other CPUs). Enable Dirac video support (an advanced royalty-free video compression format) via the reference library: dirac. Use external faac library for AAC encoding Use external fdk-aac library for AAC encoding Enable frei0r wrapping in libavfilter Build all GPL licensed code. Without this flag set the package is build under LGPL license. Use pre-calculated tables rather than calculating them on the fly. Enable mmx2 support. Enable network streaming support. Prefer dev-libs/openssl over net-libs/gnutls to provide SSL/TLS support (notice: the resulting binaries are unredistributable). Enable pulseaudio input support. Force shared libraries to be built as PIC (this is slower). Build and install qt-faststart application. Enable Real Time Messaging Protocol using librtmp instead the native implementation. Enable Dirac video support (an advanced royalty-free video compression format) via libschroedinger (high-speed implementation in C of the Dirac codec). Enable SSL/TLS support using dev-libs/openssl or dev-libs/gnutls. faster floating point optimization for SSSE3 capable chips (Intel Core 2 and later chips). Build and install small tools like aviocat, cws2fws, graph2dot, ismindex, qt-faststart. Enable VAAPI (Video Acceleration API) for hardware decoding. Adds support for SIMD optimizations for UltraSPARC processors. Enable vp8 encoding support using libvpx.
