Trying to use the Gnome-Shell buit-in desktop recorder, it's recording, creating the webm file but broked (0kb): Could not demultiplex stream. Others webm files are playing smoothly, the issue only happens when recorded here. With media-libs/libvpx-1.0.0-r1 it's works but I need to restart the gnome-shell in order to make a second record, otherwise no file is created. Maybe a Gnome-Shell issue?

================================================================= Package Settings ================================================================= media-libs/libvpx-1.1.0 was built with the following: USE="mmx (multilib) postproc sse sse2 ssse3 threads (-altivec) -debug -doc -sse3 -sse4_1 -static-libs"
I don't see why the library should be blamed for writing zero length files - especially when it only happens through a single application. Assigning accordingly.
Thanks for the report. This is a bug in media-plugins/gst-plugins-vp8 which was fixed in upstream git with the following commit: http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/commit/?h=0.10&id=04909e2c50e6802ea5dec6d0085d60d5c57f671c Assigning to gstreamer team.
I've experimented the same behavior, but Gnome-Shell desktop recorder is creating 300kb files (broken) libvpx-1.0.0-r1 partially solves the problem (I tested also libvpx-1.0.0 and libvpx-1.1.1) but as Alexandre's bug I also need to restart gnome-shell otherwise if exist any previous recording at ~/Videos folder, the new recording is appended to the existent .webm file Ubuntu has opened the same bug: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1007488 Use flags set for libvpx: (mmx sse sse2 sse3 sse4_1 ssse3 threads -altivec -debug -doc -postproc -static-libs) emerge --info
