The 0.11 porting guide
----------------------
* All deprecated methods were removed. Recompile against 0.10 with
DISABLE_DEPRECATED and fix issues before attempting to port to 0.11.
* multifdsink, tcpclientsink, tcpclientsrc, tcpserversrc the protocol property
is removed, use gdppay and gdpdepay.
* GstObject:
GST_OBJECT_DISPOSING flag removed
GST_OBJECT_IS_DISPOSING removed
GST_OBJECT_FLOATING flag remove, GstObject is now GInitiallyUnowned
GST_OBJECT_IS_FLOATING removed, use g_object_is_floating()
GST_CLASS_GET_LOCK, GST_CLASS_LOCK, GST_CLASS_TRYLOCK, GST_CLASS_UNLOCK,
used to be a workaround for thread-unsafe glib < 2.8
gst_object_ref_sink() has gpointer as result to make it more like the
GObject version.
gst_object_sink() removed, use gst_object_ref_sink() instead.
gst_class_signal_connect() removed, was only used for XML
parent-set and parent-unset signals removed. Use notify:parent. Currently
still disabled because of deep notify locking issues.
* GstElement:
GstElementDetails is removed and replaced with more generic metadata.
gst_element_class_set_details_simple() -> gst_element_class_set_metadata()
gst_element_class_set_documentation_uri -> gst_element_class_add_metadata
gst_element_class_set_icon_name -> gst_element_class_add_metadata
gst_element_factory_get_longname -> gst_element_factory_get_metadata
gst_element_factory_get_klass -> gst_element_factory_get_metadata
gst_element_factory_get_description -> gst_element_factory_get_metadata
gst_element_factory_get_author -> gst_element_factory_get_metadata
gst_element_factory_get_documentation_uri -> gst_element_factory_get_metadata
gst_element_factory_get_icon_name -> gst_element_factory_get_metadata
gstelementmetadata.h contains the keys for all standard metadata.
* GstPad:
gst_pad_get_caps() does not return writable caps anymore and an explicit
gst_caps_make_writable() needs to be performed. This was the functionality
of gst_pad_get_caps_reffed(), which is removed now.
A similar change was done for gst_pad_peer_get_caps() and
gst_pad_peer_get_caps_reffed()
