Hi,
One reason of the sample not receiving 'prepare-xwindow-id' message
could be if the file is not present in the same path as the executable.
The 'Filename' variable should be changed accordingly if it is not.
Could you tell me the format of your file and the type of video codec
present in the file?
The application supports only mov/mp4(h264 : video codec) or
mpegts(mpeg2 : video codec).
Thanks,
Jyotsana.

Hi,
I tried to reproduce the issue with your sample code but failed.
No window is created even with single video file. With gdb's help, I
found the sample doesn't receive 'prepare-xwindow-id' message.
After building the sample code ( I modified the variable 'Filename'), I
directly run MultiVideo
$> ./MultiVideo
Did I miss something?
Thanks

Hi,
I am trying to play multiple videos simultaneously using
GStreamer(vaapidecode and vaapisink plugins) and libVA-1.0.7.
In the sample application I am creating multiple windows using
"XCreateWindow" and passing the generated window ID to vaapisink.
There are two problems I am facing:
1. The first video is getting rendered but the other videos are not
getting rendered.
2. The application crashes randomly.
None of the gstreamer calls return a failure and the state is getting
changed to play successfully. Tried the application with different
container formats.
Also from the command line using "gst-launch" I am able to playback
multiple videos simultaneously.
The backtrace of the gdb log is attached "CrashLog.txt". The log
suggests the crash is in "i965_PutSurface".
I am using the following packages as mentioned on Intel Linux graphics
site "http://intellinuxgraphics.org/2010Q4.html":
2D driver: xf86-video-intel 2.14.0 release
<http://xorg.freedesktop.org/archive/individual/driver/xf86-video-intel-2.14.0.tar.bz2>
3D driver: mesa 7.10 <ftp://freedesktop.org/pub/mesa/7.10/>
Libdrm: libdrm-2.4.23 release
<http://dri.freedesktop.org/libdrm/libdrm-2.4.23.tar.bz2>
Kernel: 2.6.37 release
<http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.37.tar.bz2>
Cairo: cairo-1.10.2 release <http://cairographics.org/news/cairo-1.10.2/>
Libva: libva-1.0.7 release
<http://cgit.freedesktop.org/libva/snapshot/libva-1.0.7.tar.bz2>
xserver: 1.9.3
Apart from this I have installed the following gstreamer packages:
gstreamer-0.10.31
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.
For reference attaching the sample application "MultiVideo.c".
I am not sure if it is application problem or plugin or driver
limitation or X? As the same application runs with "ximagesink"and
decoder like ffmpeg.
What could be the problem?
PS : OS : Fedora Core 13. Platform: Sandy Bridge.Kernel : 2.6.37.
Regards,
Jyotsana.
