Andreas Rheinhardt 5bc83dd89d avfilter/vf_paletteuse: Fix leaks of AVFilterFormats on error 
The paletteuse's query_formats function allocated three AVFilterFormats
before storing them permanently. If allocating one of them failed, the
three AVFilterFormats structures would be freed with av_freep() which
does not free separately allocated subelements (namely the formats
array) which leak.

Furthermore, if storing one of the first two fails, the function simply
returns and the ones not yet stored leak.

These leaks have been fixed by only creating a new AVFilterFormats after
the last one has already been permanently stored. Furthermore, it is
enough to check whether the elements have been properly stored as
ff_formats_ref() by design returns AVERROR(ENOMEM) if it is provided a
NULL AVFilterFormats *.

Fixes Coverity issues #1270818 and #1270819.

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.
