Andreas Rheinhardt 19ae873252 avformat/wavenc: Fix leak and segfault on reallocation error 
Up until now, the wav muxer used a reallocation of the form ptr =
av_realloc(ptr, size); that leaks upon error. Furthermore, if a
failed reallocation happened when writing the trailer, a segfault
would occur due to avio_write(NULL, size) because the muxer only
prints an error message upon allocation error, but does not return
the error.

Moreover setting the pointer to the buffer to NULL on error seems to
be done on purpose in order to record that an error has occured so that
outputting the peak values is no longer attempted. This behaviour has
been retained by simply disabling whether peak data should be written
if an error occurs.

Finally, the reallocation is now done once per peak block and not once
per peak block per channel; it is also done with av_fast_realloc and not
with a linear size increase.

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
