Vadym Bezdushnyi bc04ea39a5 avformat/movenccenc: Fix memory leak for muxing CENC-encrypted files 
Memory for auxillary_info was not freed after usage.

Leak can be reproduced with following commands:

Optionally, generate input video:
ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 input.mp4

Run ffmpeg with valgrind:
valgrind --leak-check=full --show-leak-kinds=all \
ffmpeg -y -i input.mp4 -vcodec copy -acodec copy \
-encryption_scheme cenc-aes-ctr \
-encryption_key 00000000000000000000000000000000 \
-encryption_kid 00000000000000000000000000000000 \
ffmpeg_encrypted.mp4

For test video which has duration of 10 sec, leak is 4 Kb.
For 100 sec video, leak will be 33 Kb. Most likely,
leaked memory will grow linearly to the number of input frames.

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.
