File I/O, Video, 3D Canvas - all in one go!

July 18, 2008 · by csant

We have previously released experimental Labs builds containing File I/O, <video> and 3D <canvas>. For the first time we now have bundled them all into one build. On all of our desktop platforms.

Head over to the Labs to read more about the newest singing, dancing labs build… and to download your build!

WARNING: These are development snapshots: they contain the latest changes, but they also have severe known issues, including crashes and data loss situations. In fact, they may not work at all.

Your post breaks the RSS feed.
jmechy18. July 2008, 23:04:45
Confirmed about RSS being broken, the link to the page did not show at the bottom.

csant, it was pretty late in Norway at the time you made this post. Thanks for great work.

Is 3d hardware-accelerated?
davidwhodgins18. July 2008, 23:44:17
Note that everytime a blog entry contains markup language like the word canvas inside of less than and greater then signs, that terminates the text displayed in the rss feed copy of the blog.
porneL18. July 2008, 23:48:16
@davidwhodgins: @dlo§rhuj: use Atom feed instead. It doesn't have that problem.

The 3D canvas demos give me "3d canvas not supported". File IO and Video work though.

DemoWidget-OpeningFiles.wgt in the file IO examples is messed up though. (You can't see the bottom part of the widget.)

Nice! I see shadow of flying Peregrine.
chaals19. July 2008, 02:44:57
@burnout426, i noticed the same with the OLPC build (linux, static qt3). I watched it run on the mac, but my mac has been dying on me again so I can't test.

@soleen, I actually had to ask csant tocome back into the office after dinner to get this all out in time for the weekend. So thanks csant for the help.
burnout42619. July 2008, 02:51:58
@chaals

The problem is happening on WinXP for me, FWIW.
chaals19. July 2008, 03:05:34
@burnout426, that sounds odd, but I guess there is a reason these builds are called experimental. I'll note it...
burnout42619. July 2008, 03:11:02
@chaals

Thanks. Just wanted to make sure it's known.
MrGalaxy19. July 2008, 07:56:42
Hello!

Why do you give both msi and classic Opera installers for Windoo? Whether it isn't enough to give the only one?
bildos19. July 2008, 08:07:43
Acid3 test only 83% why ?
j_sk19. July 2008, 08:49:09
Opera still heading further.
tomasb19. July 2008, 09:20:48
@burnout426:

I have exactly same problem.

This is a 9.5 build, and 9.5 does not pass Acid3. This was explained back when the experimental "non-9.5" build which reached 100% was released.

Kia ora, using gmail on the Windows build started loading the gmail2 version, finally!!! But at home on my Mac the latest build still loads Gmail 1.0 Cheers!!
Sterkrig19. July 2008, 11:13:58
Woo-ha, sound great.
/me waits for 2068th build in Portage tree (-:E

@pabloaw [July 2008, 11:12:16]:

Strange. Works for me.

My configuration:

Version 9.51
Build 4886
Platform Mac OS X
System 10.5.4
Sterkrig19. July 2008, 18:14:25
Dear devs, would all this changes be merged into Kestrel branch? Or all those experimental builds are just prelude for Peregrine? Is it worth to report bugs on this build?

Here's Gentoo ebuild for this 2069:
# cat /usr/local/portage/www-client/opera/opera-9.52_pre2069.ebuild
tdik12319. July 2008, 21:26:21
Video works fine :-). 3D Canvas does not :-(
I think opera uses opengl2 features which my old graphic card does not support ...

Using Fedora 9 with
opera-9.52-2069.gcc4.qt4.i386
qt-4.4.0-12.fc10.i386
qt3-3.3.8b-14.fc10.i386

btw, i can't clear trash can. a have alot of rss feeds, i read 'em and then delete read messages. and then "empty trash". and it does nothing sinse "official" 9.50. it was ok before.

and no, i can't do "clean install", i has some messages that i want to keep. is there any way to clean trash can? can anybody confirm this so i'll fill bug report?

GNU/Linux, gcc-shared-qt3.
tenplus120. July 2008, 10:05:05
Thanks for the new experimental build... Everything seems to be working fine on my Ubuntu setup (gcc4, qt3, x86) and somehow websited load faster than before with flash playing fine... Love the new Ogg Theora movies but dont actually use RSS so cant test that part...
z-o-o-m20. July 2008, 13:46:32
nice, but ... is there something to disable it?

I mean something like "Enable JavaScript", "Enable Plug-Ins" ...
"Enable File I/O, Video, 3D Canvas"?

just curious
chaals20. July 2008, 15:49:46
@z-o-o-m hmm. If I recall correctly, disabling javascript will probably disable some features that rely on it. But in general this build is experimental, and is lacking in testing and some of the finer points of making it fit into the platforms and so on. That comes when we move from experimental to release...

@Sterkrig, this is similar to the latest desktop weekly, and at some point we expect to release these features (they're all short of final standardisation so far) in release builds. So filing bug reports is not a bad thing...
Cjcr20. July 2008, 16:42:34
Thanks for weekly build.

Bug on Google translate button's don´t work. (http://www.google.es/translate_t?langpair=en|es)

Who can explain me - what is 3D Canvas in Opera and how I can activate it?

That's obvious (-;E
But in Peregrine or Kestrel build? Just curious (-:E

All right, I'll seek for them

Ok.. the devs probably won't like this (if they read it) but..

I couldn't load gmail on my WinXP laptop after upgrading to the previous version, which was supposed to have fixed the problem. Then I tried downgrading and I still had the same problem. So I messed around with my profile folder randomly moving files. It turned out to be urlfilter.ini which had a line under [exclude] "about:blank*".

After I removed that line it worked. Not sure it it'll help anyone but you might want to try renaming your profile if it still doesn't work with this version. If it works that means there's something messed up about you profile.

It should be in:
C:\Documents and Settings\username\Application Data\Opera\Opera 9.5 alpha\profile\ or "~/.opera" if you're Linux (now wich do you prefer?)

I don't know how it ended up there or why it kept gmail from loading.

great improvements,

but what with Opera (Netscape) plug-in API modernization and support for ajax and dwf for CAD online aplications?

Mod edit: Off-topic comment removed.
haavard21. July 2008, 08:50:17
c1201298: Opera already supports the new NPAPI interface. But please try to stay on topic, OK? This blog post should be used to discuss this particular build.
feldgendler21. July 2008, 13:41:42
porneL: yes, 3D is hardware-accelerated.

burnout426 and others: 3D canvas currently *requires* hardware acceleration; please post your video card driver name and version.

Sterkrig: it's definitely worth reporting bugs.

z-o-o-m: There's no point in disabling 3D canvas. There will probably be a switch to turn off video when it makes it to a public build.
kavalec7421. July 2008, 14:56:45
I don't see the bottom of DemoWidget-OpeningFiles.wgt so I can not choose the file. Could somebody confirm?
Yahia21. July 2008, 14:59:45
OS: Win XP SP2
Opera 9.51 b10081

There's a bug I got since upgrading to 9.5.
In Mail, if I attach a file with a filname containing accents and send it, in Mail it appears to be OK, but the receiver (and my webmail - GMail) gets an altered version of the file (bizarre filename, with %s, and in the case of a Word document, it wouldn't work at all).

Please fix this.
kavalec7421. July 2008, 18:26:09
I love this build. When can we expect this great features will become aproximatly part of the regular snapshots?

Sent you an email with more details, but:

It only seems to play the first video it sees in a page.

I have many videos in a page and I expect to be able to see the first frame of every video. And then when I select the frame I get playback.
http://video.natalian.org/08/

Also in my rough tests, the caching seems to need some work.

Thanks for providing a Debian build!

Sidenote: I noticed you could use video to playback audio. I am wondering why HTML5 bothered to make the distinction.

The File I/O feature for Widgets sounds exciting. However, I would like the ability to create Widgets that add-on to Opera, much like Firefox Add-Ons. For example, an Add-On like WireMarker or NoScript is not possible on Opera.
olmari22. July 2008, 18:04:16
surfer dude, just block the scripts address, that is what I do

Don't make us laugh, look through Site Preferences
surfer dude22. July 2008, 18:38:32
You guys are getting caught up on specifics. I meant that if you had to create a Widget like NoScript or Wired-Marker, that is either somehow manipulate the HTML document or limit what is downloaded by Opera, it would not be possible on Opera. I am speaking from the perspective of writing code.
MrGalaxy22. July 2008, 19:53:25
