Thanks, I was able to get a basic pipeline going: https://github.com/frezik/Gst
The script 'introspection.pl' builds the bindings and runs code based on the GStreamer Hello, World! tutorial ( http://docs.gstreamer.com/pages/viewpage.action?pageId=327735). The ' symdump.pl' script builds every Gst*-1.0.typelib that I have on my system and dumps out all the packages it creates. The while() loop to get the messages from $bus->timed_pop() is quick, dirty, and wrong. It does let the movie play, but it doesn't catch the messages in meaningful ways. The original C tutorial uses timed_pop_filtered() like this: msg = gst_bus_timed_pop_filtered (bus, GST_CLOCK_TIME_NONE, GST_MESSAGE_ERROR | GST_MESSAGE_EOS); >From what I gathered from Glib::Flags, this should work like this: my $msg = $bus->timed_pop_filtered( GStreamer::CLOCK_TIME_NONE, [ 'error', 'eos' ]); But this causes the program to promptly exit without outputting anything. In any case, this is enough for a running start.
