video media-video@gentoo.org AAC+ encoding via media-libs/libaacplus. Enables Adaptive Multi-Rate Audio support Enables Adaptive Multi-Rate Audio encoding support with media-libs/vo-amrwbenc. Enables optimizations for armv5te processors. Enables optimizations for armv6 processors. Enables optimizations for armv6t2 processors. Enables VFP optimizations for ARM processors. Enable playback of Blu-ray filesystems Enables media-libs/libbs2b based Bauer stereo-to-binaural filter. Enables audio CD grabbing with dev-libs/libcdio. Adds Xiph CELT audio decoding support via media-libs/celt 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 Adds a text-to-speech filter based on app-accessibility/flite. Enable frei0r wrapping in libavfilter Enables fribidi support in the drawtext filter. Enables support for media-libs/game-music-emu for playing various video game music formats. Build GPL code. Should be enabled unless you require LGPL binaries. Use pre-calculated tables rather than calculating them on the fly. Support for FireWire DV/HDV input device using media-libs/libiec61883. Enables Real Time Messaging Protocol using librtmp (media-video/rtmpdump) in addition to FFmpeg's native implementation. Enables audio resampling through media-libs/soxr. Uses media-libs/libv4l for video4linux instead of direct calls. Adds support for more devices via the userspace library. Enables MIPS DSP ASE R1 optimizations. Enables MIPS DSP ASE R2 optimizations. Enables floating point MIPS optimizations. Enables network streaming support Enables dev-libs/openssl support. Adds support for encrypted network protocols (TLS/HTTPS). Adds (decoding) support for the Opus codec via media-libs/opus. Force shared libraries to be built as PIC (this is slower) Build and install libpostproc. Adds support for playing media from Internet services using the quvi project. Enable Dirac video support (an advanced royalty-free video compression format) via libschroedinger (high-speed implementation in C of the Dirac codec). Enable app-arch/snappy support. Required for e.g. Vidvox Hap encoder. Enable SSH/sftp support via net-libs/libssh. Enables MP2 encoding via media-sound/twolame as an alternative to the internal encoder. Enables vp8 codec support using libvpx: Decoding vp8 does not require this to be enabled but libvpx can also be used for decoding; encoding vp8 requires this useflag to be enabled though. Enables WebP encoding with media-libs/libwebp. Enables HEVC encoding with media-libs/x265. Enables media-libs/zvbi based teletext decoder.
