webkit-gtk and HTML5 video

[Fekete Zoltán <fekete.zoltan%minux.hu@localhost>]

Hi There,

I have tried a couple of webkit-gtk based lightweight browsers recently: 
Luakit, Midori, badwolf, vimb

None of them is capable to play any video on major sites, youtube, etc.

The player drops a message as "Your browser does not currently recognize 
any of the available video formats."

These browsers are build in pkgsrc-2020Q3 on NetBSD 9.1, amd64

Do you know what I'm missing?


Note: Firefox is working perfectly.

Thank you,

FeZ
