avformat/mov: don't abort on duplicate Mastering Display Metadata boxes
The VP9 spec defines a SmDm box for this information, and the ISOBMFF spec defines a
mdvc one. If both are present, just ignore one of them.
This is in line with clli and CoLL boxes.

Fixes ticket #10711.

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.


  • 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.


  • 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.
