video media-video@gentoo.org An open source library for media applications Enables libformat support for reading and writing various media containers. libavformat is part of FFmpeg. Enable playback of Blu-ray filesystems using media-libs/libbluray Enable support for DXR3 mpeg acceleration cards. 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. Enable support for the Fusion audio sub system Build the gdkpixbuf-based image decoder plugin. Build the ImageMagick-based image decoder plugin. 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. 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. 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. Enables VAAPI (Video Acceleration API) for hardware decoding Build the VDR plugin Enable support for vidix video output. Adds support for SIMD optimizations for UltraSPARC processors. Enable VP8 codec support via media-libs/libvpx. Enable support for XVideo Motion Compensation (accelerated mpeg playback).
