Things done: * Used Glib::Object::Introspection::GValueWrapper to wrap types for caps. This is wrapped in GStreamer1::Caps::Simple to mimic the original GStreamer Perl module * Fleshed out docs, particularly some porting notes * Fleshed out adding to the pipeline and linking elements in examples/ rpi_src.pl
All the above has been pushed to github. In examples/rpi_src.pl, a callback is being set on a fakesink to grab the jpeg and save it to a file. It doesn't seem that this is getting called. The light does come on for my Raspberry Pi's camera module, so the pipeline should be running and grabbing data from the camera. I realize that this could be done more simply by setting "location=/path/to/file" on a filesink, but I want to do it this way because: 1) I want to provide an example of using a signal callback 2) My app needs to do more than just save the data to the file Feel like things are really close now.
