Hi,

I use ruby-gnome2 bindings to operate on GStreamer.

When my pipeline raises an error, I catch it on the bus.

The message that I receive is associated with so-called “structure”,  
which actually contain two keys, for example:

gerror = #\<#Class:0x7f7960ee7b78:0x7f7960ee78d0\>  
debug = gsttcpserversrc.c(437): gst\_tcp\_server\_src\_start ():  
/GstPipeline:pipeline0/GstTCPServerSrc:tcpserversrc0:  
bind failed: Address already in use

as debug can be translated by OS, I need to get into code of gerror.  
Seems that class is unnamed, and contains no specific functions to the  
GError.

Is there any way to read that?

m.

hi marcin -

not sure if this helps at all - i may well be misunderstanding the  
question - but i use gstreamer with gtk2, and i parse the error messages  
like this…

bus = @pipeline.bus  
bus.add\_watch {|bus, message|  
case message.type  
when Gst::Message::ERROR  
p message.parse  
Gtk.main\_quit  
…}
