Hi,

I am trying to use the gstreamer-vaapi-0.2.5 plugin for video playback
using the hardware decoder.
I am working on Fedora Core 13 on Calpella platform and using the following packages as
mentioned on Intel Linux graphics site
(http://intellinuxgraphics.org/2010Q2.html) :

2D driver: xf86-video-intel 2.12.0 release
3D driver: mesa 7.8.2 release
Libdrm: libdrm-2.4.21 release
Kernel: 2.6.34 release
Cairo: cairo-1.9.8
Libva: libva-1.0.3
xserver-1.8.1.

Apart from this I have installed the following gstreamer packages:
gstreamer-0.10.29
gst-plugins-base-0.10.29
gst-plugins-good-0.10.22
gst-plugins-bad-0.10.19
gst-plugins-ugly-0.10.15
gst-ffmpeg-0.10.10.

And also,
ffmpeg-0.6.

vainfo displays the following infomation:
libva: libva version 0.31.1
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/i965_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA API version: 0.31
vainfo: Driver version: i965 Driver 0.1
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointVLD
VAProfileH264Baseline : VAEntrypointVLD
VAProfileH264Main : VAEntrypointVLD
VAProfileH264High : VAEntrypointVLD

When I run the sample application "test-decode" present in
gstreamer-vaapi/tests folder, I get an x11 window but it does not
display any content(i.e a blank screen appears).

Also if I try to playback video using gst-launch with the following pipeline :
gst-launch filesrc location= ! ffdemux_mov_mp4_m4a_3gp_3g2_mj2 ! vaapidecode ! vaapisink

I get similar result as above , i.e , a blank screen. Also it does not return any errors.

What could be the problem?

Regards,
Jyotsana.
