About FLV files

FLV is the video format of Adobe Flash, used by older websites and download tools. Most FLV files contain H.264 video with AAC sound.

Browsers can’t play FLV files directly. Open Online decodes them with a built-in player that runs inside the page.

What you can do here

  • Play the file with your browser’s player, or with Open Online’s built-in player for AVI, WMV, FLV, MPEG and TS
  • See resolution, duration and codecs
  • Watch in full screen

Limitations

  • Whether a file plays depends on the codecs your browser supports. For AVI, WMV, FLV, MPEG and TS files the built-in player opens the container, your browser decodes H.264, HEVC and AAC (a recent Chrome, Edge or Safari is needed), and built-in decoders cover older codecs such as MPEG-1/2/4, WMV, AC-3 and DTS.
  • Older codecs are decoded on your processor, so large high-resolution files in those may skip frames. Nothing is transcoded or uploaded.

Privacy

The file is read by your browser and stays on your device. Open Online has no server that could receive it, and nothing is stored once you close the tab. Privacy policy

Common questions

Why does my old FLV show a codec error?

The oldest Flash videos use On2 VP6 video, which the built-in player does not include. FLV files with H.264 video (decoded by your browser) or Sorenson Spark video play.
