There is a problem with decoding .webm files with VP9 codec under Windows platform. When I try to open such files, I receive segmentation fault message. There is a similar bug already reported as fixed (https://bugzilla.gnome.org/show_bug.cgi?id=761147) but it concerns vaapi, which is not available on Windows platform and the issue still persists in GStreamer 1.12.4.

The problem appears in:

external Java application (using JNA bindings from https://github.com/gstreamer-java/gst1-java-core) - JVM crashes completely with no logs
gst-play-1.0 (Segmentation fault message for both a.webm and flaque2.webm)
gst-launch-1.0 (Segmentation fault message for both a.webm and flaque2.webm)
Used command: gst-launch-1.0 -v filesrc location=a.webm ! matroskademux ! vp9dec ! videoconvert ! videoscale ! autovideosink
gst-discoverer-1.0 (works fine for a.webm, but Segmentation fault message appears for flaque2.webm)

Sample files for testing are included in an attachment (flaque2.webm comes from the linked 761147 bug, the other file is my own).
