Andreas Rheinhardt c253b180cb tools/graph2dot: Don't use sizeof(AVFilterGraph), check allocation 
Use avfilter_graph_alloc() instead of av_mallocz(sizeof(AVFilterGraph))
to allocate an AVFilterGraph; this also properly allocates the graph's
internal. The current code just happened to work because it did not
make any use of said internal.

Also check the allocation; this fixes Coverity #1292528.

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.

Documentation
