[gst-devel] pipeline for VDPAU

[lonkaji]

Hi,

I don't understand why but after a reboot I now can play h264 files using
gstreamer-vaapi! (with just this line: gst-launch-0.10 filesrc
location=/home/camtrace/harry.mp4 ! qtdemux ! vaapidecode ! vaapisink)

Now I would like to display RTSP streams from IP cameras (Axis P1343).
Here is the result:

gst-launch-0.10 rtspsrc
location=rtsp://192.168.0.127/axis-media/media.amplatency=0 !
rtph264depay ! h264parse ! vaapidecode ! vaapisink

It seems there are some problems with RTSP and caps.
Anyone can help me?
Is gstreamer-vaapi have been tested with RTSP streams ?
Thanks for your help.
