unless you installed h264 decoder, it should not work, YouTube service
HTML5 videos as VP9, VP8, or mp4, you can see by right clicking the

working for you.
I think Konq does not support any free video codec (VP9 or VP8),
Firefox supports BOTH (but now YouTube only runs VP8 on Firefox
because Google wants 'Media Sources Extensions' available to run VP9,
and MSE support in Firefox is still experimental)
KWebKitPart uses GStreamer to decode videos. WebM (VP8, VP9) is supposed to
just work.
https://www.youtube.com/html5 also tells me that WebM VP8 is
supported. (As for VP9, unfortunately, as you wrote, they apparently use it
only with Media Source Extensions, which is currently NOT supported. But
even Firefox is not enabling it by default, as you wrote.)
And there are GStreamer plugins for H.264 in RPM Fusion. Unfortunately, you
will need them for other sites anyway. A lot of the web still refuses to use
patent-unencumbered formats. :-( For some reason, YouTube seems to send
H.264 over VP8 if both are supported.
