About CAF to FLV Conversion
CAF is Apple's professional audio container for macOS Core Audio. FLV (Flash Video) is Adobe's legacy streaming container. Flash Player reached end-of-life in December 2020.
Converting CAF to FLV enables macOS professional recordings to enter legacy Flash streaming pipelines. From lossless CAF sources, the AAC/MP3 encoding has optimal source quality.
Why Convert CAF to FLV?
Legacy RTMP streaming servers and Flash-based platforms require FLV input. Converting CAF to FLV bridges macOS professional audio with these legacy systems.
The lossless CAF source ensures the best possible audio quality within FLV's codec constraints.
Common Use Cases
- Providing Logic Pro recordings for legacy RTMP streaming
- Preparing macOS audio for archived Flash platforms
- Converting professional recordings for Adobe Media Server
- Building Flash-compatible content from professional sources
- Supporting RTMP ingest from macOS audio workflows
How It Works
FFmpeg reads CAF, decodes to PCM, and encodes to AAC or MP3 within FLV. From lossless CAF sources, only one lossy step occurs. FLV metadata is in the onMetaData script tag.
Quality & Performance
AAC at 128-256 kbps from lossless CAF produces excellent FLV audio. Single lossy step from perfect source material.
