Security vulnerabilities in codecs
“AFAIK, since the codec is enabled by default, anyone who processes a maliciously crafted .mp4 file with ffmpeg is vulnerable.”

Comment from 12 Nov 2025 in “FFmpeg to Google: Fund us or stop sending bugs” “The main failing of the ffmpeg team is that they should have spent more time on architectural hardening and mitigations.”
Comment from 13 Jun 2026 in “Twenty One Zero-Days in FFmpeg” Unhelpful defaults
“ffmpeg's defaults (reencoding by default and only keeping one stream of each type unless otherwise specified) aren't great”
Comment from 27 Dec 2025 in “Show HN: Ez FFmpeg – Video editing in plain English” “Can't make frame perfect cuts without re-encoding, unless your cut points just so happen to be keyframe aligned.”
Comment from 17 Mar 2026 in “Lazycut: A simple terminal video trimmer using FFmpeg” Build and upgrade dependency pain
“getting the stock ffmpeg to compile/build might be "easy", but once you start adding on additional codecs and other features that get you into dependency nightmares "easy" is not the word I would use”
Comment from 17 Mar 2026 in “FFmpeg 8.1” “Over the years I've had to upgrade the ffmpeg dependency, which resulted in breaking changes a couple times and maintenance.”
