To get "zbus" messages by using gst_parse_launch () function

Ru Vuott
Hello,

In:
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-plugins/html/gst-plugins-bad-plugins-zbar.html
the guide says "zbar" plug-in sends bar codes as element messages to the "GstBus".

To read/get those messages from "GstBus", have I use "gst_element_get_bus()" function ?

Thanks
vuott

No, always get the GstPipeline bus (gst_pipeline_get_bus()). Then add a
watch on the bus if you are using a GMainLoop, or poll the bus if not
to get the messages asynchronously. You'll have to filter the messages.
