What decoder is needed to play youtube videos?

Using Andreas' meta-raspi-light (which removes userland and only uses vc4)
I've spent the last hour or so watching youtube videos from my raspberrypi3
(32-bit build) in chromium, accelerated, with sound (both via the HDMI and the
jack), both on the big monitor and the 7" waveshare touchscreen. Not to
mention I can now run openGL and GLESx apps accelerated.

I wasn't able to do that with userland. In fact, it was quite a struggle just
to get it to build!

Maybe I did something wrong with userland, but vc4 is successful, and
certainly easier to work with.
