Split out the registration of the metadata API and its implementation. Make a
GType for each metadata API. This allows us to store extra information with the
API type such as the tags.
Change the buffer API so that we can get the metadata using the API GType.
Change the query API so that we use the metadata API GType in the allocation
query instead of a string.
Update netaddress and unit tests
Add support for adding tags to the metadata. with some standard keys, this
should make it possible to describe what the metadata refers to. We should be
able to use this information to decide if a transformation destroys the metadata
or not.
lseek() returns the offset if successful, and this is != 0 and
does not indicate an error. And if it does actually fail, don't
return FALSE (0) as an int, but -1. None of these things are
likely to have made a difference, ever. I don't think the offset
seek can ever actually happen, the current file position and the
current offset should always be increased in lock step, unless
there was an error in which case we'd just error out.
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.
Flesh out the transform method. Add a type and extra info to the transform
function so that implementation can transform the metadata.
Remove the copy function and replace with the more generic transform.
Make it possible to configure a GDestroyNotify and user_data for
gst_memory_new_wrapped() this allows for more flexible wrapping of foreign
memory blocks.
Don't use the duration in the segment for calculating clipping values.
The duration is expressed in stream time and clipping is done on unrelated
timestamp values.
This used to be interesting for elements that used the segment structure to
implement seeking because then they would use stream-time for the segment
start/stop values and the duration could be used as a fallback when the stop
position was not set. Now that the complete segment event is passed between
elements we cannot do this anymore because some elements might store the
duration and start/stop values with different time bases in the segment.
When we have no chain function or when we are operating the pad in the wrong
mode, emit a critical instead of posting an error message. This is certainly a
programming error and we cannot always post a message (like when the pad has no
parent)
Rename _is_writable() with _is_exclusive because the writability does not depend
on the amount of references to the memory object anymore.
Add accessor macros for the memory flags.
Rename the GstBuffer _peek_memory() method to _get_memory() and return a
reference to the memory now that we can do this without affecting writability
of the memory object. Make it possible to also make this function merge the
buffer memory.
Add methods to replace memory in a buffer. Make some convience macros for the
buffer memory functions.
Fix unit tests.
Make an _init method where the parent mini-object and other fields are
initialized.
Check that the passed structure doesn't already have a parent.
Use the _new_custom () constructors
__registry_reuse_plugin_scanner is only defined when
GST_DISABLE_REGISTRY is not defined.
gstregistry.c: In function 'gst_registry_scan_plugin_file':
gstregistry.c:1131:8: error: '__registry_reuse_plugin_scanner' undeclared (first use in this function)

Fix annoying gst_type_find_register() function signature. A simple
string with comma-separated extensions works just as well and saves
lines of code, casts, relocations and ultimately kittens.
Place the allocator object in the ALLOCATION query instead of the name. This
allows us to exchange allocators that are not in the global pool of allocators.
Update elements for the new api
Add refcounting to the GstAllocator object.
Remove const from functions because the allocator is refcounted now.
Rename the vmethods for consistency
Expose the constructor for GstAllocator and add a destroy notify for the
user_data. This should make it possible to create allocators that are not
registered and shared globally along with the possibility to destroy them
properly.
Update defs with new symbols.
Remove trace, we use debug log for that
Make alloc trace simpler, removing some methods.
Activate alloc trace with a GST_TRACE=3 environment variable.
Dump leaked objects atexit.
Provide an offset in the object where the GType can be found so that more
verbose info can be given for objects.
Remove -T option from gst-launch because tracing is now triggered with the
environment variable.
We don't use the sticky event index anymore, ordering of the events are how they
were sent initially.
Add some more padding between the event numbers so that we can insert new events
later.
Since GValueArray is deprecated. It's all only internal anywhere here,
but if we use GstValueArray the option strings get serialized nicely
in the debug logs at least.
This is now bindings firendly as _new is just a classic c convenience and all
the work is done in a constructor. As a side effect _new never fails.
Fix the tests.
int and int64 ranges can now have an optional step (defaulting to 1).
Members of the range are those values within the min and max bounds
which are a multiple of this step.

We introduced our own when GLib didn't want to add a GType
for GError. But now that there is one, we can use GLib's
unconditionally and remove our version.
Make the memory object simply manage the data pointer and the maxsize and move
the offset and size handling to common functionality.
Use the READONLY flag to set a readonly lock.
Remove the data and size fields from the unmap method. We need an explicit
resize operation instead of using the unmap function.
Make internal helper lock and unlock functions.
Update unit test and users of the old API.
This has to be handled explicitely by elements to
make sure that they support all the metas passed
in the allocation query.
Metas have to supported explicitely, otherwise the
query will fail. All elements in a chain need to
support a specific meta to allow its usage.
Which we had to add because GLib didn't have it
back in the day. Port everything to plain old
G_TYPE_DATE, which is also a boxed type. Ideally
we'd just use GDateTime for everything, but it
doesn't support not setting some of the fields
unfortuntely (which would be very useful for
tag handling in general, if we could express
2012-01 for example).
