Original commit message from CVS: * examples/gstreamer/filesrc.py,player.py: New examples * gstreamer/gstreamer.override: Add a dict like interface to GstTagList * gstreamer/gstpad-handlers.override: New file, split out from gstreamer.override * gstreamer/gst-types.defs: Don't use gst_buffer_free/gst_data_free, use gst_data_unref instead. * gstreamer/gst-types.c (PyGstData_to_value): Don't send address here. * gstreamer/arg-types.py (GstDataPtrArg.write_param): Send the address to stuff, since we really want to avoid segfaults :) * gstreamer/0.6.[c,defs,h,override]: Remove, we're focusing on 0.7 * gstreamer/0.7.[c,defs,h,override]: Remove, merge with gstreamer.* * gstreamer/Makefile.am: Clean up, remove versioning support.
