Why it doesn’t play

Screen and game recordings often use a variable frame rate, and some files simply have a wrong audio offset. Bluetooth headsets add their own delay.

Play it free with PlayAnyVideo

  1. 1

    In PlayAnyVideo, adjust the audio/subtitle delay in small steps until lips and voice match.

  2. 2

    Try wired headphones to rule out Bluetooth delay.

  3. 3

    If the browser can’t decode it, the built-in universal engine (open-source, LGPL) takes over automatically.

  4. 4

    For the heaviest files (4K/8K HEVC, DTS, TrueHD) install the free Windows app: it converts on the fly with your graphics card and plays everything.

  5. 5

    On Android, choose “Open with → PlayAnyVideo” from your file manager or messenger.

FAQ

Is it really free?

Yes. PlayAnyVideo has no ads, no paid codecs and no locked features.

Is my Microsoft Teams recordings file uploaded anywhere?

No. Playback happens on your own device; local files are never sent to a server.

Do I need a codec pack?

No. Codec packs can break other players and often bundle adware. PlayAnyVideo brings its own decoders.
