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.
