FLV (Flash Video) was once the dominant format for streaming video on the web, used by early YouTube, Dailymotion, and countless Flash-based media players. While Flash has been officially deprecated since 2020, FLV files are still encountered in legacy content management systems, archived web content, and certain Chinese video platforms that continue to use the format. Converting AMR voice recordings to FLV wraps the audio in this legacy container.
The primary reason to convert AMR to FLV today is compatibility with legacy systems that specifically expect FLV input. Some older CMS platforms, Flash-based e-learning tools, and archived web infrastructure were built around FLV and have not been updated. If you need to inject a voice recording into one of these systems, FLV may be the required format.
FFmpeg decodes the AMR audio and re-encodes it as MP3 (the standard audio codec for FLV), then packages it inside an FLV container with no video track. The FLV metadata tag includes duration information for seeking. The output is a valid FLV that Flash-based players can stream or play locally.
The MP3 encoding inside FLV at 128 kbps is more than adequate for AMR-sourced speech content. Since AMR captures only 3.4-7 kHz of bandwidth, the MP3 encoder easily preserves all available detail.

AMR to FLV conversion is a specialized workflow for legacy Flash systems. For modern use, consider MP4 or WebM instead.
