FFmpeg 9.1's new AAC encoder

FFmpeg 9.1 has been released with a new native AAC encoder, offering improved audio quality and performance over previous versions. The update brings enhancements to the popular multimedia framework, benefiting users who rely on FFmpeg for audio encoding tasks.

Background

- FFmpeg is the leading open-source multimedia framework used by virtually every major video player, streaming service, and editing tool (VLC, YouTube, OBS, etc.) to encode, decode, and process audio/video files. - AAC (Advanced Audio Coding) is the dominant lossy audio codec, used in YouTube, Apple Music, Spotify (vs. Ogg Vorbis), and most streaming platforms. It succeeded MP3 for better quality at similar bitrates. - Version 9.1 marks a major upgrade to FFmpeg's built-in native AAC encoder (the "native" one, not the external library-based encoders like libfdk_aac). - Prior to this, FFmpeg's native AAC encoder was widely considered inferior in quality to alternatives — this release claims significant improvements, potentially reducing the need for users to install external codecs (which may have licensing or distribution complications).

Roman Storm warns that the legal theory in his case could set a precedent making open-source developers liable for how others use their code, potentially criminalizing the mere publication of privacy, messaging, or crypto tools. He notes that developer Michael Lewellen cannot publish lawful code due to prosecution fears, and argues this chilling effect extends beyond any single case.

Meta's engineering culture is deteriorating under Mark Zuckerberg and Scale AI CEO Alexandr Wang, who have introduced keyboard tracking, reassignments to data labeling, and AI-centric performance metrics. Critics argue this incentivizes performative AI use, drives away experienced engineers, and contributed to a major Instagram hijacking incident caused by AI-written and AI-reviewed code.
