[Libva] codec parser issues between gst-plugins-bad and gstreamer-vaapi

[Javier Jardón]

Hi,

I have problems too since the codecparsers get integrated in
gstreamer-vaapi.
For example, if I try to play a MPEG-4 (Divx) file I get a crash:

libva: va_openDriver() returns 0
*** stack smashing detected ***: gstpenang terminated
