Bug ID: 764169
Summary: Dogslow VP9 4k playback
Classification: Platform
Product: GStreamer
Version: 1.6.3
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-bad
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: nekohayo at gmail.com

GNOME version: ---
Totem can't play this at more than ~0.1 fps (or something like that):

Tested with libvpx 1.4.0. CPU usage suggests it's single-threaded.
VLC plays the file butter-smooth, using as many CPU threads as needed.
Specs are:
- Intel Xeon W3520 @ 2.67GHz × 8
- 24 GB of RAM
- Radeon HD 7770 running the open-source drivers (Gallium 0.4, DRM 2.43.0) on X
