Flash installed in the computer but undetected by Nuvola

Thanks for taking the time to report this bug. However, I need more
information to investigate it further.

1) Could you provide versions of following libraries on your system?
libglib2, gtk+-3.0, glib-2.0, gio-2.0, libsoup-2.4 and webkitgtk-3.0.

2) WebKitGtk provides a testing tool that is usually located at
/usr/lib/webkitgtk-3.0-0/libexec/GtkLauncher. This tool can be used to
decide, whether the bug is caused by WebKitGtk itself or just Nuvola
Player uses it in a bad way. Unfortunately, the tool seems not to be
provided by an Arch Linux package [1]. Could you ask maintainer of the
package about an easy way how to install the WebKit GtkLauncher?

  status incomplete

My current version of the packages are:

libglib2 = 2.32.4 (included with glib-2.0)
gtk+-3.0 = 3.4.4
glib-2.0 = 2.32.4
gio-2.0 = N/A (either unneeded in ArchLinux or included with glib-2.0)
libsoup-2.4 = 2.38.1
webkitgtk-3.0 = 1.8.3

Since I have no developer privileges, I am currently unable to ask the developer or maintainer of the libwebkit3 package to add the GtkLauncher program. I could try to find a version in the AUR to compile it myself and test it, but that would take some trial and error.

> webkitgtk-3.0 = 1.8.3

I have 1.8.1 on my system and it detects flash successfully. I'll try
to install 1.8.3 then.

I supposed the maintainers of packages have some public contact
information for feedback. Maybe you could create a bug report for
inclusion of GtkLauncher. However, it's a while since I used Arch
Linux, so I don't remember what's the recommended way how to create a
feature request.

I'll create a simple webkit browser window. It will be much easier
then compilation of WebKit GtkLauncher.

I have the same problem.
ArchLinux x86_64 with
glib2 - 2.32.4
gtk3 - 3.4.4
libsoup - 2.38.1
libwebkit3 - 1.8.3

Could you build attached simple WebKitGtkBrowser and perform following tests?

1) Run the browser and check whether the Flash plugin is detected. Attach output from terminal.
2) Install nspluginwrapper as described at [1] and repeat step 1.

[1] https://wiki.archlinux.org/index.php/Epiphany#Flash

Output of NDISWrapper and the WebKit browser provided. NDISWrapper did nothing because the Flash version is already 64-bit.

It's necessary to wrap 32bit Flash plugin. I'm currently playing with
that and I'll provide a short how-to when ready.

> Plugin: Shockwave Flash (true): /usr/lib/mozilla/plugins/libtotem-vegas-plugin.so

You have installed Vegas plugin that identifies itself as Flash. Could
you uninstall it temporarily and post new debug output? Also output of
`ls /usr/lib/mozilla/plugins` would be appreciated.

Second output. The Totem plugins were removed as requested. The problem continues: now the Flash plugin is totally undetected.

I believe this bug is caused by an incompatibility between GTK+-3-based Nuvola Player and GTK+-2-based Flash plugin, so I'm marking this bug as a duplicate of meta-bug #1058586 to track all issued caused by the incompatibility in one place.

Could you follow instructions at bug #1058586 and help with testing of a development branch that should address this issue?
