About RMI to FLV Conversion
RMI (RIFF MIDI) is Microsoft's RIFF-containerized MIDI format, used by the Windows Multimedia Extensions and DirectX audio subsystems from the early 1990s through the Windows XP era. The RIFF wrapper integrates MIDI playback with Windows' unified multimedia architecture, allowing the same APIs that handle WAV playback to manage MIDI sequencing through the midiStream interface.
FLV (Flash Video) is Adobe's legacy streaming container, once the backbone of web video through Flash Player. Converting RMI to FLV extracts MIDI from the Windows RIFF container, renders it through a software synthesizer, and packages the audio in an FLV container. Since Flash Player reached end-of-life in December 2020, this conversion serves primarily for legacy content management systems and RTMP-based streaming infrastructure.
Why Convert RMI to FLV?
Some legacy content management systems, educational platforms, and RTMP-based media servers still require FLV format for multimedia content. Organizations migrating Windows-era multimedia training content from RMI may need FLV output to feed into Flash-era LMS installations or corporate intranet media systems that have not been upgraded.
FLV is also relevant for legacy RTMP streaming infrastructure. If your media delivery pipeline uses Wowza, Adobe Media Server, or similar RTMP-based systems, FLV may be the required ingest format for rendered RMI audio content.
Common Use Cases
- Uploading rendered Windows RMI audio to legacy Flash-based e-learning platforms requiring FLV
- Streaming synthesized RMI music through RTMP-based enterprise media server infrastructure
- Converting Windows corporate training RMI audio for Flash-era content management systems
- Preparing rendered RMI background music for legacy intranet media players using FLV format
- Integrating Windows multimedia archive audio into existing FLV content libraries for preservation
How It Works
FFmpeg reads the RIFF container, extracts the MIDI data chunk from the RMID form, and synthesizes audio through a SoundFont engine. The rendered PCM is encoded — typically as MP3 or AAC — and wrapped in an FLV container using FLV's tag-based structure (audio tags with timestamps, optional scriptData metadata tag). Since MIDI contains no visual data, the FLV output holds only an audio stream with FLV header flags indicating audio-only content.
Quality & Performance
FLV is a container that does not affect audio quality beyond the chosen codec. MP3 at 192-320 kbps or AAC at 128-256 kbps within FLV delivers standard lossy audio quality. The SoundFont used for MIDI synthesis determines the musical character, not the FLV container. The rendering engine and codec dominate the quality equation.

Tips for Best Results
- 1Use MP3 encoding inside FLV for maximum legacy Flash system compatibility — some older systems only support MP3 in FLV containers
- 2Consider converting to MP4 or WebM instead of FLV unless your specific workflow requires the Flash container format
- 3Set the audio bitrate to at least 128 kbps for acceptable music quality within the FLV container
- 4Include FLV onMetaData with duration and audio properties for proper seeking in RTMP streaming players
- 5Test FLV playback in VLC before deploying to legacy systems — VLC validates container structure and codec compatibility
RMI to FLV converts Windows RIFF MIDI content into a legacy streaming container. This is a niche conversion — use it only when legacy Flash or RTMP infrastructure requires FLV format.
