Andreas Rheinhardt e7aea1fe73 avformat/dashdec: Fix leak of string on error when parsing representation
The DASH demuxer currently extracts several strings at once from an xml
document before processing them one by one; these strings are allocated,
stored in local variables and need to be freed by the demuxer itself.
So if an error happens when processing one of them, all strings need to
be freed before returning. This has simply not been done, leading to
leaks.

A simple fix would be to add the necessary code for freeing; yet there is
a better solution: Avoid having several strings at the same time by
extracting a string, processing it and immediately freeing it. That way
one only has to free at most one string on error.

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.

  • 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.
