[Intel-gfx] Crash of repeated playback using libva and gstreamer

[Jyotsana]

Hi,

I am trying to play multiple video files one after the other using 
GStreamer(vaapidecode and vaapisink plugins) and libVA-1.0.3.
I am able to play one file successfully but once the first file is 
played to completion, we delete all references of the first pipeline and 
create a new one.
When the second file is played, application crashes with the following 
error:

libva: libva version 0.31.1
libva: va_getDriverName() returns 0
libva: Trying to open /opt/X11R7/lib/dri/i965_drv_video.so
libva: va_openDriver() returns 0
libva: libva version 0.31.1
libva: va_getDriverName() returns 0

Following is the backtrace obtained from gdb:

I am running this on Fedora Core 13 on Calpella Platform.
What could be the problem? :-(
