Make gst_caps_do_simplify() take ownership of the input caps and produce a
simplified output caps. This removes the requirement of having writable input
caps and the method can make the caps writable only when needed.
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.
Make a helper function check_sticky to check and push pending sticky events.
Move the handling of the result of pushing the sticky event inside the
push_event function, we need to mark the event as received when it was pushed
correctly.
Move the sticky events code outside of gst_pad_push_event_unchecked and
make it purely handle sending the event to the peer.
when pushing a sticky event, first store it on the pad. Then check and push any
pending sticky events when we get a serialized or sticky event on a srcpad. This
fixes the issue where sticky events are not pushed when an event is pushed.
There isn't really any need to provide public API for that. It's not
used anywhere in practice, and we aim to provide an API that works
for GstCaps, not some kind of generic set manipulation API based on
GValue. Making this private also makes it easier to optimise this
later. We can always put it back if someone actually needs it.
Because gst_pad_get_pad_template_caps() returns ANY when there is no template,
the query caps function should also return ANY when there is no template (and no
pad current caps) instead of EMPTY.
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)
https://bugzilla.gnome.org/show_bug.cgi?id=667284
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.
