Pipelight-multi displaying plugin-needed in firefox 35

[James Stewart Miller]

I have just reinstalled pipelight-plugin as it is not working at all and I am still getting the same problem. Firefox on youtube is reverting to the html5 plugin, but the youtube videos on facebook are not visible at all, with firefox stating that a required plugin is missing.

I have installed it properly and updated the dependency installer script and am still having the same problem.

Can you suggest anything? I seem to have had the problem since the upgrade to wine-staging. I tried wine-staging out of interest on playonlinux for world of tanks, and got a message about ****stack smashing**** which appears to be related to how the wine version wine-staging was built with the gcc flag stack-protection on enabled. There is also a message about pulseaudio refused - I am using alsa.

I am on Lubuntu utopic unicorn and am running a 3.18.1 low latency custom kernel.

Many thanks.

pipelight-plugin --list-enabled-all
silverlight5.1
flash

I can't get debug output from console as firefox forks immediately and I can't seem to find the command to get it output console level debug info. I tried gdb but there wasn't anything interesting/

Based on the system check everything is fine. Does Silverlight/Flash appear correctly in about:plugins ? If not, do you see a "Pipelight Error" somewhere?

Please note that specific browser plugins like NoScript, HttpsEverywhere, FlashBlock, ... are known to break browser plugins. Please disable them in your browser profile for testing.

[James Stewart Miller (jamesstewartmiller)]

I've got no silverlight/flash plugins reported in about:plugins at all.
The only addon I'm using is uacontrol

Thanks

As for pipelight error when I start firefox in a terminal it forks immediately. If I run firefox --help I get this:

I've tried using the debugger but it doesn't really output any interesting info.

I'm using google-chrome-stable for flash and silverlight at the moment as it supports flash and silverlight natively. I'm guessing that firefox will have this soon as well.

[Sebastian Lackner (slackner)]

Concerning Google Chrome: I hope you mean HTML5 DRM and not Silverlight. Silverlight doesn't exist natively on Linux, and using Pipelight is also not possible anymore since they decided to drop the NPAPI plugin interface from their browser.

Back to the main problem: Since firefox is unable to find the plugin your issue is not related to any wine version. Maybe you are using a broken firefox build, which can't load plugins from a global location. Try to enable the plugin for your current user by running:

sudo pipelight-plugin --disable-all

(and now, without sudo!)
pipelight-plugin --enable silverlight5.1 --enable flash

Does firefox then load the plugin (= does it appear in about:plugins)?
If not, try using a different browser (for example Midori) to confirm that this is a firefox specific issue.

[James Stewart Miller (jamesstewartmiller)]

installed midori and it installs the plugins silverlight and flash, as does firefox but no joy

Why "no joy"? Everything initializes successfully:
[PIPELIGHT:WIN:silverlight5.1] init successful!
[PIPELIGHT:WIN:flash] init successful!

Moreover I don't see any crash in the logs. This means it should work some basic demos which do not require a user agent switcher, like:
http://bubblemark.com/silverlight2.html

What exactly does not work? If you want to use it on VOD pages like Netflix you will have to change your user agent to Windows Firefox (can be changed in Settings->Network).

[James Stewart Miller (jamesstewartmiller)]

Ok, so midori is working with silverlight ok, but youtube plays with html5 player rather than flash. Firefox doesn't show either plugin at all.

[Sebastian Lackner (slackner)]

You should check if other plugins are still working fine in firefox (Java, Moonlight, ...). If not, then this means that the current Ubuntu firefox packages for 14.10 are basically broken.

Concerning Youtube: It depends on a lot of factors if it uses HTML5 or Flash, for example which formats are reported as supported by the browser. You should try with a website which only supports Flash for testing.

[James Stewart Miller (jamesstewartmiller)]

I've just checked my other machine, which is also running utopic lubuntu, and a generic 3.16 low latency kernel, and firefox is showing flash and silverlight in the about:plugins.
So, I've just tried running it at youtube and a pipelight error occurred so I ran sudo pipelight-plugin update, and then restarted firefox. The updated flash installer worked and then at youtube it used the html5 player. I then checked the plugins and flash is *not* listed anymore(?). I went to netflix with uacontrol installed and got a 'pipelight error during initialisation'.
On this machine thought, Midori hangs at youtube even with the html5 player.
