avcodec/jpegxl_parse{,r}: fix integer overflow for some malformed files 
If there's a very large ISOBMFF box that needs to be skipped, it can
cause an overflow for ctx->skip. There's already a safeguard to return
quickly if ctx->skip > bufsize, so changing ctx->skip to int64_t will
allow this to happen even if ctx->skip would overflow a signed int.

Several other members are also changed to int64_t to avoid this problem
in other possible scenarios.

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.
