James Almer 5f5421ec66 swscale/swscale: prevent integer overflow in chrRangeToJpeg16_c 
Same as it's done in lumRangeToJpeg16_c(). Plenty of allowed input values can
overflow here.

Fixes: src/libswscale/swscale.c:198:47: runtime error: signed integer overflow: 475328 * 4663 cannot be represented in type 'int'

  • 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.
