Andreas Rheinhardt edaf8c9615 avcodec/opus_silk: Remove wrong size information in function declaration 
silk_lsp2poly()'s declaration contained arrays with array sizes;
yet these array sizes exceeded the number of actually accessed array
elements (which is related to another parameter) and this leads to
-Wstringop-overflow= warnings from GCC 11, because the arrays provided
by callers are only large enough for the actually used elements.

So replace the incorrect array sizes with comments containing
the correct array sizes. Given that these sizes are not compile-time
constants, they can only be communicated via a comment.

Reported by Paul B Mahol.

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.
