how to load aravis plugin with python-gstreamer

Hi All,

I managed to use aravis plugin from shell script as shown below.
How can I do same sort of thing from python?

Thanks much,
Bert Douglas

LD_PRELOAD=/usr/lib/libaravis.so                                         \
gst-launch --gst-plugin-load=/usr/lib/gstreamer-0.10/libgstaravis.so     \
     aravissrc camera-name=""      \
   ! ffmpegcolorspace       \
   ! autovideosink

Why do you have to LD_PRELOAD the lib?

Re: how to load aravis plugin with python-gstreamer

Because the so file for the plugin is defective. It lacks a reference to libaravis. You can see this with ldd.
