Andreas Rheinhardt 18af922c53 avformat/iamf: Don't mix ownership and non-ownership pointers 
IAMFAudioElement and IAMFMixPresentation currently contain
pointers to independently allocated objects that are sometimes
owned by said structures and sometimes not.

More precisely, upon success the demuxer transfers ownership
of these other objects newly created AVStreamGroups, but it
keeps its pointers. iamf_read_close() therefore always resets
these pointers (because the cleanup code always treats them
as ownership pointers). This leads to memory leaks in case
iamf_read_header() without having attached all of these
objects to stream groups.

The muxer has a similar issue: It also clears these pointers
(pointing to objects owned by stream groups created by the user)
in its deinit function.

This commit fixes this memleak by explicitly adding non-ownership
pointers; this also allows to remove the code to reset the
ownership pointers.

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 means to alter decoded audio and video through a directed graph of connected 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.
