AIFF stores pristine uncompressed audio from Apple's professional ecosystem, while FLV (Flash Video) is Adobe's legacy streaming container. Converting AIFF to FLV packages audio for RTMP streaming infrastructure, which still powers a significant portion of live streaming despite Flash's browser deprecation in 2020. The audio is typically transcoded to MP3 or AAC within the FLV wrapper.
RTMP ingest endpoints (used by OBS, Streamlabs, Wirecast, and streaming CDNs like Wowza and Akamai) transport data in FLV packets. If you need to push high-quality audio from an AIFF source to an RTMP endpoint, converting to FLV is the required intermediate step. Some legacy content management systems and archived Flash-based websites also require FLV files.
FFmpeg decodes the AIFF PCM stream and transcodes to AAC (preferred, better quality) or MP3 (broader legacy support) inside an FLV container. FLV supports AAC since Flash Player 9 and MP3 since Flash Player 6. A minimal video track may be added for players that require one. The FLV container adds metadata (onMetaData) for duration, bitrate, and codec information.
Encoding from uncompressed AIFF produces first-generation lossy audio — the best possible quality for the target codec. AAC at 192 kbps or MP3 at 320 kbps from AIFF source is perceptually transparent.
