Gstreamer Vaapi plugin

[jyotsanasingh]

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 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.


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).
What could be the problem? :-( ....


Thanks and Regards,
Jyotsana.

try to get some output setting GST_DEBUG to 2 or more. Also setting
your video sink property "sync" to false will help you to understand
something more. If the process gets completely stuck (eg no audio as
well) running it with gdb and getting a backtrace of the point where
it deadlocks will help even more.
