Andreas Rheinhardt 710ab13693 avfilter/vf_unsharp: Don't dereference NULL 
The unsharp filter uses an array of arrays of uint32_t, each of which is
separately allocated. These arrays also need to freed separately; but
before doing so, one needs to check whether the array of arrays has
actually been allocated, otherwise one would dereference a NULL pointer.
This fixes #8408.

Furthermore, the array of arrays needs to be zero-initialized so that
no uninitialized pointer will be freed in case an allocation of one of
the individual arrays fails.

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 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.

Documentation
