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) Build binary redistributable version without including nonfree decoders and encoders. Enable audio CD grabbing with dev-libs/libcdio. Enables runtime CPU detection (useful for bindist, compatibility on other CPUs). 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). Use the external opus library for encoding and decoding. Enable pulseaudio input support. Force shared libraries to be built as PIC (this is slower). 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. Enable WebP encoding with media-libs/libwebp. Enable HEVC encoding with media-libs/x265.
