Andreas Rheinhardt ddee53e268 avcodec/vp9: Fix stack-buffer overflow with VP9 VDPAU available 
ccca62ef99 added new VP9 VDPAU profiles
and as a consequence AV_PIX_FMT_VDPAU can now be twice in the list of
pixel formats used for format negotiation by ff_thread_get_format(); yet
there is only one entry in said list reserved for VDPAU, leading to a
stack-buffer overflow. This commit fixes this by making sure that
AV_PIX_FMT_VDPAU will not occur twice in said list.

Fixes Coverity ticket 1468046.

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.
