Wim Taymans 7b0e4f27fb memory: make _new_wrapped take user_data and notify
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.

Wim Taymans c6a1bed1ad memory: more work on refcount and writability
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.

Wim Taymans 16d9a9efbe memory: add memory type
Add memory type when registering memory allocators. Add getter for the memory
type.

Wim Taymans af2fc026fc memory: make the allocator refcounted
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.

memory if it is currently in use.
2012-01-25 11:54:23 +01:00
Wim Taymans a521252845 Add new GstMapInfo
Use a structure to hold info about the mapping. The application then keeps track
of this state and we can use it to unmap the memory again later.
2012-01-25 11:54:23 +01:00
Wim Taymans a1d7bd02e4 memory improvements
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.

Tim-Philipp Müller 10d901291e gst: suppress some more deprecated thread api until we fix it up

Wim Taymans c96d5a330c memory: make writability check into a method
Use a method to check for writability instead of a macro so that we can change
the implementation more easily.

Wim Taymans 960c580ae2 memory: handle -1 size in unmap

2012-01-06 07:02:36 +01:00
Wim Taymans e4a58ec71e memory: improve semantics of unmap
Make an unmap call with a different data pointer than the map call update the
offset field. This allows for both offset and size adjustements in the unmap
call.

Wim Taymans f3b0d3cdbe init: add _get_type() functions
Remove gst_mini_object_register() and add a GST_DEFINE_MINI_OBJECT macro to
define a _get_type() function for the boxed miniobject.
Remove a bunch of custom _get_type() functions and replace them with the
miniobject macro.
Rename some _init method to _priv_*_initialize() like the rest of them.

Inspired by patch from Johan Dahlin and see bug #657603

Wim Taymans 8461249f22 buffer: fix negative offsets some more
Allow for negative offsets when doing memory copy and share.
Add fast path in the _get_sizes() function.
Fix resize for negative offset and expanding the buffer.
Add some unit tests.

Wim Taymans abf6293639 buffer: add api to get the current memory offset
Also return the offset in a GstMemory block with the get_sizes() method. This
allows us to figure out how much prefix there is unused.
Change the resize function so that a negative offset can be given. This would
make it possible to resize the buffer so that the prefix becomes available.
Add gst_buffer_get_sizes() to return the offset and maxsize as well as the size.
Also change the buffer resize method so that we can specify a negative offset
to remove prefix bytes.

Wim Taymans b84fff07ea memory: Require implementation to implement _share
Require the memory implementations to implement a share operation. This allows
