Andreas Rheinhardt ab4795a085 matroskadec: Add sizes to forward declarations
Unknown-length elements end when an element not allowed in them, but
allowed at a higher level is encountered. In order to check for this,
c1abd95a added a pointer to every syntax level's parent to each
EbmlSyntax. Given that the parent must of course also reference the
child in order to be able to enter said child level, one needs to use
forward declarations.
These forward declarations constitute tentative definitions and tentative
definitions with internal linkage (like our syntaxes) must not be an
incomplete type. Yet they were an incomplete type and while GCC and
Clang did not even warn about this (on default warning levels), it
broke compilation with MSVC. Therefore this commit adds the sizes.

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.
