Fullscreen on YouTube (flash) isn't really full screen

jjacky · 2011-11-26 12:29:17

So this is a little weird. First of all, let me state that I am using Arch inside a VM (Win7 host), using XFCE and Firefox as my browser, should that matter.

Okay, so I noticed that when I fullscreen a video a YouTube, it doesn't get "fully" in FS mode, that is I get black bars on top & bottom of the screen for some reason. It's not due to the video, and in fact the player bar (with play/pause button, volume, etc) isn't at the bottom of the screen, but above that "black bar" of unused space.

After looking it up, I found out that it was apparently due to a bug in flash (oh yeah, I use flashplayer. Tried gnash but it basically didn't work; and html5 doesn't get me good results either FYI) that had to do with the fact that I have two monitors.

But then, yesterday I came accross this video: http://www.youtube.com/watch?v=9kIyhiIY8hc
And the unique thing about it, is that when I fullscreen it, I get a "real" FS, with the player bar at the bottom of the screen and everything. At first I thought it might be due to some recent update (though except for FF going from 8.0 to 8.0.1 I don't think I updated anything related recently), but I guess not since other videos still do not FS "completely."

But that's not all. From that video above there's a link to other videos, at the end of it (related videos). One of those is this one: http://www.youtube.com/watch?v=i7Wuw_2721U

Now, if, from the "real" FS, I click on it, I get to see that second video in "real" FS just like the first one. But if I open it "manually" going to that link, I have the same "buggy/incomplete" FS.
In fact, if I open the first video and go FS, I am in "real" FS. Then I can watch the second video in the same "real" FS. But if then I leave FS mode, the page gets refreshed to go to that (second) video's page, and then going FS again will get me the "incomplete" FS.

(Just in case I did try both videos in 720p, then again but in 360p, doesn't matter. Also, I usually do this from my main monitor, but I tried from the second one and results are the same.)

In the end, it looks to me like Flash could totally play (all) videos in "real" FS, but somehow it only works when I switched to FS from that first video, for some mysterious reason. I tried looking at variables sent to the flashplayer or things like that, but couldn't really see anything.

So, does anybody else with a dual monitors setup that suffers from the "not real" FS bug with flash experience this as well? Does anybody have any idea on what's going on, or what I can do to always have a "real" FS?

Thanks,

There are many settings in YT, one is full screen, the other is 'expand', maybe you clicked the wrong one?
Does it happen in another distro or Windows?

jjacky · 2011-11-26 13:00:47

No, I click FS.
On Win7 (host) the FS mode works as expected; I haven't tested in other distros, but I should have a Fedora VM available, I'll test.

if you're on dual head setup, the bug is old and still unfixed. i suggest you flash video replacer for firefox

I am not on arch64 anymore but the bug is old, pretty well know and AFAIK was never really fixed for Flash. Unfortunately Flash under Linux (esp. the 64 Bit version) has always been a PITA.
Even here under the latest Xubuntu 11.10 with ATI 4670HD (with radeon drivers) I still run in the same issues I had previously under an older version of Ubuntu with a NVidia 9800GT plus propritary drivers.

Gnash (or other flash replacements) never worked well for me.

Workarounds I see:
1) Start Firefox in a dedicated Xorg server configured for single head
2) Use Windows Firefox with Flash under WINE plus emulated desktop
3) Download flashvideo and look afterwards in Mplayer, VLC and so on (this is what I mostly do)
4) Disable dualhead for watching flash videos

Yes I had read about that bug, but just assumed it meant FS simply never works on a dual head setup. Which is why I was surprised to see that, for at least that first video, it does.

Anyhow, didn't know about that FlashVideoReplacer add-on, pretty cool, thanks. Now my flash videos are "redirected" to VLC, where I can have a "real" FS as I want. Nice; Thanks guys.

Hi,

Don't know if it can help, but I fixed it using this.

It redirects you here, and it worked like a charm for me.

kokoko3k · 2011-11-28 18:52:08

It looks like it would work.

...What a shame on Adobe and/or Nvidia that someone has successfully fixed their bugs without even watching their code.

jjacky · 2011-11-28 20:04:31

Yeah, all videos get a proper FS with that thing, good stuff.

Thanks.

just tested, It doesn't work for me:

echo running without the hack...
running without the hack...
./tester
XGetGeometry reports width=2560 height=1024
echo running with the hack...
running with the hack...
LD_PRELOAD=./libfullscreenhack.so ./tester
fullscreen hack loaded...
XGetGeometry reports width=2560 height=1024

Anyway something changes on firefox, fonts are bigger, youtube videos are the same

There's a package for that https://aur.archlinux.org/packages/fullscreenhack

I hope jjacky is not waiting with bated breath. They will be a bit blue after four years.
