OGV files contain Vorbis audio — Xiph.org's lossy audio codec — alongside Theora video. FLAC (Free Lossless Audio Codec) is another Xiph.org project, providing lossless audio compression that reduces PCM to 50-60% size with zero data loss. Both Vorbis and FLAC come from the same open-source ecosystem, making this a natural extraction path within the Xiph.org format family.
Extracting OGV audio to FLAC creates a lossless archival copy of the decoded Vorbis audio. While the source is lossy, the FLAC output serves as a master copy from which you can produce any future lossy format (MP3, AAC, OGG) without cascading generation losses from lossy-to-lossy transcoding.
FLAC is also the standard for open-source lossless audio, supported natively on Android, Linux, Windows, and most media players worldwide.
FFmpeg extracts the Vorbis audio stream from the OGV container, decodes to raw PCM, and encodes using the FLAC encoder. Compression levels 0-8 control the speed-size tradeoff (level 5 default). Output is typically 16-bit/44.1 kHz matching the Vorbis source parameters. FLAC uses Vorbis comments for metadata, the same system used in OGG — tags can be preserved or modified during conversion.
FLAC losslessly preserves every sample of the decoded Vorbis audio. The quality ceiling is the original Vorbis encoding quality — FLAC cannot improve on it but ensures no further degradation. The decoded audio is bit-perfect on FLAC playback.
