xine-lib

USE flags

• a52 - Enable support for decoding ATSC A/52 streams used in DVD
• aac - Enable support for MPEG-4 AAC Audio
• aalib - Add support for media-libs/aalib (ASCII-Graphics Library)
• alsa - Add support for media-libs/alsa-lib (Advanced Linux Sound Architecture)
• bluray - Enable playback of Blu-ray filesystems using media-libs/libbluray
• cpu_flags_ppc_altivec - Use the AltiVec/VMX instruction set
• css - Enable reading of encrypted DVDs
• dav1d - Enable support for media-libs/dav1d AV1 decoder
• dts - Enable DTS Coherent Acoustics decoder support
• dvb - Add support for DVB (Digital Video Broadcasting)
• dxr3 - Enable support for DXR3 mpeg acceleration cards.
• fbcon - Add framebuffer support for the console, via the kernel
• flac - Build the media-libs/flac based FLAC demuxer and decoder. This flag is not needed for playing FLAC content, neither standalone nor in Ogg container (OggFLAC), but might have better support for exotic features like 24-bit samples or 96kHz sample rates.
• gtk - Build the gdkpixbuf-based image decoder plugin.
• imagemagick - Build the ImageMagick-based image decoder plugin.
• ipv6 - Add support for IP version 6
• jack - Add support for the JACK Audio Connection Kit
• jpeg - Add JPEG image support
• libcaca - Add support for colored ASCII-art graphics
• mad - Build the media-libs/libmad based mp3 decoder. This mp3 decoder has superior support compared to the one coming from FFmpeg that is used as a fallback. If you experience any bad behaviour with mp3 files (skipping, distorted sound) make sure you enabled this USE flag.
• mmap - Use mmap() function while reading file from local disks. Using mmap() will use more virtual memory space, but leaves to the Kernel the task of caching the file's data. mmap() access should be faster, but might misbehave if the device where the file resides in is removed during playback.
• mng - Add support for libmng (MNG images)
• modplug - Add libmodplug support for playing SoundTracker-style music files
• musepack - Enable support for the musepack audio codec
• nfs - Allow accessing NFS shares via net-fs/libnfs.
• nls - Add Native Language Support (using gettext - GNU locale utilities)
• opengl - Add support for OpenGL (3D graphics)
• oss - Add support for OSS (Open Sound System)
• pulseaudio - Add sound server support via media-libs/libpulse (may be PulseAudio or PipeWire)
• samba - Add support for SAMBA (Windows File and Printer sharing)
• sdl - Add support for Simple Direct Layer (media library)
• sftp - Use net-libs/libssh2 to access SFTP servers.
• speex - Add support for the speex audio codec (used for speech)
• theora - Add support for the Theora Video Compression Codec
• truetype - Use media-libs/freetype for font rendering and media-libs/fontconfig for font discovery. Enabling this USE flag will allow OSD (such as subtitles) to use more advanced font and to more easily select which font to use. The support for TrueType fonts in xine-lib is still experimental, and might not be as good looking as the bitmap fonts used with this USE flag disabled.
• v4l - Enable support for video4linux (using linux-headers or userspace libv4l libraries)
• vaapi - Enable Video Acceleration API for hardware decoding
• vcd - Video CD support
• vdpau - Enable the Video Decode and Presentation API for Unix acceleration interface
• vdr - Build the VDR plugin
• vidix - Enable support for vidix video output.
• vis - Adds support for SIMD optimizations for UltraSPARC processors.
• vorbis - Add support for the OggVorbis audio codec
• vpx - Enable VP8 codec support via media-libs/libvpx.
• wavpack - Add support for wavpack audio compression tools
• wayland - Enable dev-libs/wayland backend
• X - Add support for X11
• xinerama - Add support for querying multi-monitor screen geometry through the Xinerama API
• xv - Add in optional support for the Xvideo extension (an X API for video playback)
• xvmc - Enable support for XVideo Motion Compensation (accelerated mpeg playback).
