They can be used to select snapping behavior (to previous, next, or
nearest location, where relevant) when seeking.
The seeking implementation (eg, demuxer) may currently ignore some
or all of these flags.
It's only used internally, most other users will likely
want to use gst_registry_find_plugin() directly instead
(and if not, they can easily walk the list and doing the
strcmp themselves).
There's no reason anyone would want to derive from this, so
just make opaque until we manage to make all the private bits
private properly (which I'm not doing right now because it's
more invasive and I have registry modifications locally which
touch all that code as well).
This is an implementation detail really, and it's not
clear what anyone would do with this. It's unused as
far as I'm aware, so just remove it for now.
Rename the _get_value_array() functions to _get_g_value_array() and reintroduce
the former to operate on plain unboxed c datatypes (like in 0.10). The _g_value
variants are for bindings while the _value ones are more suited to processing
in elements.
Reset the buffer not after we acquire but before we release into the pool. This
makes sure that the pool only has buffers in a clean state and that we can set
extra metadata on buffers in the acquire method. this means that we need to
remove an argument from the method.
Add a new LOCKED flag to the metadata. Refuse removing LOCKED metadata from
a buffer.
Mark the metadata from the bufferpool LOCKED.
Add unit test for LOCKED flag
Ass serialize and deserialize functions for GstSegment so that gdp and
gst_structure_to_string show the segment values. We convert to a GstSegment
first to make things easier..

Add gst_element_class_{add,set}_metadata() variants for static strings,
so we can avoid unnecessary g_strdup()s.
API: gst_element_class_add_static_metadata()
API: gst_element_class_set_static_metadata()
After a writer has written to its reserved write location, it can only make the
location available for reading if all of the writers with lower locations have
finished.
Fix a race where the reader would see the updated the tail pointer before the
write could write the data into the queue. Fix this by having a separate reader
tail pointer that is only incremented after the writer wrote the data.
