#3410 closed defect (fixed)

Browse should enable plugins

Reported by: manuq Owned by: dsd
Priority: Unspecified by Maintainer Milestone:
Component: Browse Version: Git as of bugdate
Severity: Unspecified Keywords: 12.1.0, upstream
Cc: erikos Distribution/OS: OLPC
Bug Status: Unconfirmed

Description (last modified by manuq)

WebKitGTK+ settings [1] "enable-plugins" and "enable-java-applet" have default value TRUE, so plugins should work out of the box.

UPDATE: the following is false, see comment 4 below.

However, a simple test (attached) shows that this is not the case at least for the Python bindings. Plugins do not work by default, and setting "enable-plugins" to False makes Flash work. So this may be a bug in pygobject, inverting the booleans.

Gonzalo suggested csotts's preloading hack as a workaround. We can either add a workaround, or wait for WebKit2, as the fix is almost there for landing upstream.

Sorry previous comment was for #3411.

comment:3 Changed 12 years ago by manuq

Also in Epiphany, if I uncheck "Enable plugins" in Preferences, only then I can see plugins.

Tested in F17 with webkitgtk3 1.8.0, and in F16 with webkitgtk3 1.6.1 .

Sorry, I've been fooled by the html5 video in youtube, the interface mimics flash quite good now. The hypothesis of the inverted functionality in "enable-plugins" should be dropped.

The right page to test for Flash is:

comment:5 Changed 12 years ago by manuq

This piece of Python code will show the plugins that are available in the system for WebKit:

from gi.repository import WebKit
db = WebKit.WebPluginDatabase()
for p in db.get_plugins():
    print p.get_name(), p.get_path()

os7: Flash is working out of the box with Gnash (has version 0.8.10).

Youtube test:

In XO-1.5 I see a black area in the video area. In XO-1.75 goes a bit
further: I can see the video preview with the play button in the
middle after the page loads. After clicking on it, fails because of
missing codecs. This is a gnash known issue. Two messages pop up
with errors for audio and video codec.

Adobe "find flash player version" test:

Works, I can pause/play, toggle fullscreen.

Also works the animation of the spheres. The video test fails for the
same reasons as youtube video.

Browse In XO-1.75 is having sporadic crashes.

Tested IcedTea in XO-1.5 and XO-1.75. If I go to a page with a Java
plugin, I can't see it, a little blue cage is displayed instead. Then
if I change to another page, crash.

Tested in my devel machine running F16. Works fine in Firefox.
Doesn't work in Epiphany, a little blue cage is displayed. No crash
of the browser.

Then I tried to install sun java, downloaded the rpm.bin and executed it,
after that I did the symlink but java is not listed in the plugins for
firefox. Maybe I should remove icedtea entirely instead of just
moving the .so binary out of /usr/lib/mozilla/plugins .

Here's the bug reported for IcedTea in Epiphany at RedHat bug tracker:

Trying adobe flash player... unsuccessfully.

In olpc build os8 with XO-1.5 .

Went to the adobe page, . It guess I'm using chrome or open source chromium browser. I downloaded adobe-release-i386-1.0-1.noarch.rpm and installed it. This installs a repo in /etc/yum.repos.d/adobe-linux-i386.repo .

I then installed flash-plugin (18M) using yum install flash-plugin . This replaces gnash, overriding the symlink in /usr/lib/mozilla/plugins/ that now points to

/usr/lib/flash-plugin/ . The plugin database test in comment 5 shows it, I removed (which also claims to provide Shokwave Flash) just in case.

Then opened Browse and tried the same pages as in the gnash test in comment 7 but they don't show the flash embeds, the blue box with the ? sign is displayed instead (as with java in IcedTea.

Same happens inside Epiphany.

Tested Sun Java for i386 and ARM, it works in current Browse.

For i386

I followed this instructions:

I downloaded jre-7u4-linux-i586.rpm in XO-1.5 os8. Installed the
package, did the symlinks specified in the instructions with the
"alternatives" command.

Only had to change the command for, seems a mistake in the
instructions for i386. The command to use is:

alternatives --install /usr/lib/mozilla/plugins/  /usr/java/jre1.6.0_31/lib/i386/ 20000


I tried in XO-1.75 os8:

  • Java SE for Embedded 7
  • ARMv7 Linux - Headful
  • EABI, Hard Float (VFP), Little Endian

I uncompressed the tarball and did this symlinks:

sudo ln -s /home/olpc/ejre1.7.0_04/lib/arm/ /usr/lib/mozilla/plugins/
sudo ln -s /home/olpc/ejre1.7.0_04/bin/java /usr/bin/java

  • Owner changed from manuq to dsd
  • Status changed from new to assigned

Fixed upstream. Test RPMs with the patch included:

Works with nspluginwrapper.

comment:15 Changed 12 years ago by manuq

Installed the test RPM, nspluginwrapper via yum, and adobe flash in XO-1.5 olpc build os12. Then opened Browse and navigated to . Flash does not work, the area of the embed is filled grey. The logs shows this line several times:

** Message: console message:  @0: event.layerX and event.layerY are broken and deprecated in WebKit. They will be removed from the engine in the near future.

Patch attached.

comment:16 Changed 12 years ago by dsd

Yes, you have to do some extra steps. You can find them in the adobe_flash module in olpc-os-builder.

comment:17 Changed 12 years ago by dsd

If you want to test, best way is to build your own OS image with adobe_flash module included.

comment:18 Changed 12 years ago by dsd

  • Resolution set to fixed
  • Status changed from assigned to closed

This is fixed upstream and in OLPC OS 12.1.0.
