Ganesh Ajjanagadde 16d4c28cbb avcodec/mpegaudio_tablegen: speed up dynamic table creation This does some miscellaneous stuff mainly avoiding the usage of pow to achieve significant speedups. This is not speed critical, but is unnecessary latency and cycles wasted for a user. All tables tested and are identical to the old ones (bit-exact even in floating point case). Sample benchmark (x86-64, Haswell, GNU/Linux): old: 102329530 decicycles in mpegaudio_tableinit, 1 runs, 0 skips new: 34111900 decicycles in mpegaudio_tableinit, 1 runs, 0 skips Reviewed-by: Ronald S.

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
ffserver is a multimedia streaming server for live broadcasts.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.
