MPG is the legacy disc and broadcast format using MPEG-1/MPEG-2 codecs, while FLV (Flash Video) was Adobe's proprietary streaming format that dominated web video from roughly 2005 to 2015. FLV supported Sorenson Spark, VP6, and eventually H.264 video with MP3 or AAC audio. While Flash Player has been discontinued since 2020, FLV files are still encountered in legacy web archives, old content management systems, and RTMP streaming infrastructure.
Converting MPG to FLV serves legacy scenarios where FLV format is specifically required. Older content management systems, Flash-based e-learning platforms, and RTMP streaming servers may still need FLV input. Some digital media archives also contain large FLV collections, and adding MPG content requires format consistency. While no one should start new FLV projects, maintaining existing Flash-era infrastructure sometimes necessitates this conversion.
FFmpeg decodes MPEG-1/2 video and MP2 audio from the MPG container, then re-encodes to H.264 (or H.263 for strict Flash 7 compatibility) with AAC or MP3 audio in the FLV container. The FLV container supports H.264+AAC since Flash Player 9 Update 3. Injecting onMetaData events ensures proper seeking in Flash-based players. Keyframe placement every 2 seconds supports RTMP stream switching.
Using H.264 inside FLV produces quality equivalent to or better than the original MPEG-2 at the same bitrate, thanks to H.264's superior compression. Using Sorenson Spark (for very old Flash compatibility) results in quality comparable to MPEG-1 — acceptable for standard definition only.

MPG to FLV conversion exists purely for legacy compatibility. For any new project, use MP4 or WebM instead. But for maintaining Flash-era infrastructure, this conversion provides reliable, correctly-formatted FLV output.
