What is FLV?

FLV (Flash Video) is a legacy multimedia container designed for delivery through Adobe Flash Player and RTMP streaming. A .flv file stores media as sequential “tags,” typically carrying H.263/Sorenson Spark or On2 VP6 video in older files and H.264/AVC in later ones, with MP3 or AAC audio. It also embeds timing metadata and cue points for web playback and simple interactivity. Because Flash reached end-of-life in 2020 and browsers removed the plug-in, FLV is now mainly used when converting archival content. Most modern players—VLC, mpv—and tools like FFmpeg can open and transcode FLV, but MP4 (H.264/AAC) or WebM (VP9/Opus) are preferred for size, compatibility, and HTML5 streaming. If you have FLV files, consider remuxing or re-encoding to MP4, and delivering via HLS or DASH.

What is MPEG?

MPEG (.mpeg or .mpg) usually refers to the MPEG-1/2 Program Stream container plus its classic video codecs. An .mpeg file typically holds MPEG-1 or MPEG-2 video with MP2/MP3 (or sometimes AC-3) audio, multiplexed for smooth playback on computers, set-top boxes, and legacy DVDs/VCDs. The compression is lossy and block-based, great for the era of low bitrates, but less efficient than modern H.264/AVC or HEVC at the same quality. Most players—VLC, Windows apps, QuickTime, and many TVs—open MPEG natively; editors can often remux to MP4 or MKV without re-encoding if codecs are supported. Note that MPEG-2 Transport Streams use .ts or .m2ts, and MPEG-4 files usually use .mp4, not .mpeg. Converting old MPEG to MP4 (H.264/AAC) yields smaller files and broader web compatibility.
