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.
