Andreas Rheinhardt dff0a1557e tests/checkasm/llauddsp: Avoid UB integer overflow 
The only multiplicators used in scalarproduct_and_madd_*
are -1, 0 and +1. Yet it is of type int and the checkasm
test uses the complete range of int for it, leading to overflows
that don't happen for actual users.

Fix this by using a more reasonable range for mul: Given
that it is used in v1[i] += v3[i] * mul with v1 being
a 16bit integer, it makes no sense to use values for mul
that don't fit into 16bit.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • 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 means to alter decoded audio and video through a directed graph of connected 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.
