Andreas Cadhalpun 859a348e44 dca: fix misaligned access in avpriv_dca_convert_bitstream src and dst are only 8-bit-aligned, so accessing them as uint16_t causes SIGBUS crashes on architectures like sparc. This fixes ubsan runtime error: load of misaligned address for type 'const uint16_t', which requires 2 byte alignment Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> (cherry picked from commit `44ac13eed4`) Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>		2016-01-28 02:15:49 +01:00

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 analisys tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
