[gst-devel] vdpau/vaapi with gst

[th.tom at gmx.de]

Hi all,

I would love to use hardware supported decoding with my nvidia ion with gstreamer.

I was able to compile vaapi successfully with nvidia/vdpau support:

------snip------
vainfo: 
libva: libva version 0.31.1-sds1
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/va/drivers/nvidia_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA API version: 0.31
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA API - 0.6.10
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            :	VAEntrypointVLD
      VAProfileMPEG2Main              :	VAEntrypointVLD
      VAProfileH264Main               :	VAEntrypointVLD
      VAProfileH264High               :	VAEntrypointVLD
      VAProfileVC1Simple              :	VAEntrypointVLD
      VAProfileVC1Main                :	VAEntrypointVLD
      VAProfileVC1Advanced            :	VAEntrypointVLD

and added/compiled gstreamer-vaapi-0.2.5 successfully.

Then I started a simple playbin and it recognizes the vaapi but does fail playing:

same happens, when I build up a manual pipeline ..

I am using (from std ubuntu 10.4/lucid):
$ gst-launch-0.10 --version
gst-launch-0.10 version 0.10.28
GStreamer 0.10.28
https://launchpad.net/distros/ubuntu/+source/gstreamer0.10

Any ideas??

Thanks in advanced
