Andreas Rheinhardt 340e6b0185 avcodec/adxdec: Remove unnecessary left-shift Replace "(a * (1 << shift) * b + c) >> shift" by "a * b + (c >> shift)". It is equivalent to the old code because a is in the range of uint16_t, shift is 12 and b is effectively a signed 4-bit number, so that no overflow/truncation of high bits happens during the multiplication (overflow would be undefined anyway).

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.
Additional small tools such as aviocat, ismindex and qt-faststart.
