Well, AFAIK you only really need gstreamer support for non-free formats (i.e.,
MP4, MP3). In fact, perhaps that's why that 1080p video only played in 360p:
maybe the 1080p version is only available as an MP4 (youtube-dl could probably
verify)?
Of course, for all I know you don't care about playing non-free formats, and
that'd be fine.
It's just that I can't deactivate FlashDisable and expect YouTube
to default to HTML5 videos yet (see the top of the quoted text above).
FWIW, I *did* try it and still got the undesired behaviour (Youtube
trying to use Flash).
I think we're talking past each other here. FlashDisable is irrelavant
to the way I do it. The really important concept is that each profile
is a separate universe unto itself. And you can set totally different
behaviours in each profile. In my Youtube profile, I totally disable
Flash. As far as the web page is concerned, I don't have Flash
installed at all. Like I said above, FlashDisable is irrelavant
to the way I do it. Here's the Seamonkey menu tree; Firefox may be
different.
Tools == Add-ons Manager == Plugins (on the left sidebar)
I select Shockwave Flash from the Plugins list, and there's a
dropdown menu with 3 choices
* Ask to Activate
* Always Activate
* Never Activate
I select Never Activate, and Youtube thinks I don't have Flash
installed, forcing it to go with HTML5 mode.
Yeah, you're right, we were talking past each other :) .
(FWIW, that's exactly the same menu tree as in Firefox.)

I think (emphasis on the think) that qtwebkit needs libxml2 with -icu, and chromium needs libxml2 with +icu. Thank you for your answer and sorry for the delay in replying to it. When I first read your comment, I wanted to write: You've got it! But now, when the issue is solved, I should acknowledge that the qtwebkit has not required -icu, it was just compiled with -icu by default and that created the blocker. As far as I can tell from reading a couple bug reports, it looks like you can rebuild qtwebkit with -gstreamer (since that's what causes the !icu? blocker) and then you should be able to install chromium. Apparently icu is pretty annoying. Alternatively, you could just uninstall qtwebkit if you're not using it for anything. These your suggestions actually forced me to delay the answer, as I needed time to check which of my application packages depend on qtwebkit and if I really need gstreamer. Now, when the problem has been solved, it is not so important but nevertheless: 1. At least the app-text/goldendict, that I need very much, depends on qtwebkit. 2. I am not sure but my guess is that the gstreamer allows me to watch the video from youtube (partially), edX, cousera, etc. in a web-browser (I mainly use Firefox), as I never install any flash player to avoid too many flashing while browsing the Internet. (Would be interested to know if this my guess is correct.)

That way you could resolve that blocker. It works. I have discovered it myself earlier today. Nevertheless, it is odd as -icu for qtwebkit was set by default. PS: you'll likely still need to enable icu on libxml2 afterwards unless you already did so.
