Andreas Rheinhardt 840f192540 avformat/iamf_writer: Remove nonsense check 
Checking whether a pointer to an element of an array is NULL
makes no sense, as the pointer addition involved in getting
the address would be undefined behaviour already if the array
were NULL.
In this case the array allocation has already been checked
a few lines before.
Fixes Coverity issue #1559548.

  • 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.
