KakaoTalk and phone videos won't play? Play HEVC free.

If a video you received on KakaoTalk, LINE, WhatsApp or from an iPhone shows only sound, a black screen or a message asking you to buy a codec, the video is almost certainly encoded in HEVC (H.265).

HEVC decoded on your device — free

Why it happens

HEVC halves file sizes, so modern phones record in it by default. Windows does not include a free HEVC decoder and offers a paid extension in the Microsoft Store instead. Many browsers can only decode HEVC when your graphics card supports it.

The fix: OpenPlay

  1. 1

    Install OpenPlay for Windows (free, ad-free).

  2. 2

    Double-click the video or drag it onto OpenPlay.

  3. 3

    OpenPlay detects HEVC and decodes it with its built-in open-source engine — no purchase, no upload.
