Doesn't work. As soon as I downgrade libvpx and install official gstreamer0.10-bad all is working again.

So, something in libvpx 1.1.0 is breaking gnome shell desktop recording tool.

Can't you run gnome-shell-desktop-recoridng tool from a command line and check for errors?

Also I bet it's not libvpx's fault, but the program using it

Of course, it could be. Just tell me which command line I have to use.

As I do not modify anything, I just have this in dconf-editor for gnome shell recorder settings :

pipeline = ""

So by default : vp8enc quality=8 speed=6 threads=%T ! queue ! webmmux

Edit : looking at https://bugzilla.gnome.org/show_bug.cgi?id=676653#c9 (bug which I opened), there is test-recorder binary in gnome-shell sources. Will try to see what happens with it and libvpx 1.1.0

Well, as I cannot find test-recorder in official gnome-shell package, I tried to build it from scratch.

test-recorder is built, but segfaults on start.

[20560.131892] test-recorder[2282]: segfault at 140 ip 00007f1c7792c3a1 sp 00007fff1ccdf7f8 error 4 in libc-2.15.so[7f1c778aa000+197000]
[20584.114419] test-recorder[2284]: segfault at 140 ip 00007f8a5c82a3a1 sp 00007fffa4beb6f8 error 4 in libc-2.15.so[7f8a5c7a8000+197000]

Any idea ?

Got some infos. Fix had been applied upstream, see https://bugzilla.gnome.org/show_bug.cgi?id=676245

All is needed : a new gstreamer-plugins-bad (0.10.24 ?) when it will be released ;)

git fix from gstreamer plugins bad 0.10.xx branch : http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/commit/?h=0.10&id=04909e2c50e6802ea5dec6d0085d60d5c57f671c

Well, when gnome 3.6.x will be in extra, you can close this bug.
