------------------------------------+--------------------------------------
Large zero-filled files can cause libavcodec to allocate very large
quantities of RAM.
I ran across this when forked-daapd was scanning a directory that
contained large pre-allocated files, but did not yet have any actual data
in those files.
Reproduction is easy.
# truncate -s8G badfile.m4v
# ffprobe badfile.m4v
