Convert incoming straight alpha color to premultiplied at filter begin,
and process premultiplied value at filter end.
If direct rendering is allowed, we assume the input source outputs
premultiiplied alpha. If not, that source will need to be updated.
This adds the drmbuf format as a parameter separate from the obs texture
format that will be used. drmbuf's may have a variety of formats that we
need to pass correctly to get a usable texture which may correspond to
multi-platform texture formats.
Implements the Undo/Redo for scenes and sources, ranging from renaming,
deletion, addition. It also adds several elements to libobs that were
designed to facilitate undo/redo, and should not affect the rest of
libobs.
Implements obs_data_get_defaults and updates the documentation. This is
supposed to allow someone to access all the defaults of an object.
Should help in cases where the full data is needed, and not just the
currently set.
If obs was shutting down in very early in initialization like when the
X11 display is missing this context parameter might still be NULL.
Return early to allow shutdown to complete without crashing.
macOS should use the function clock_gettime_nsec_np() to get the
current clock in nanoseconds, instead of manually using
mach_absolute_time() and manually adjusting the timebase. This
greatly simplifies the platform-specific code to manage the
current time in nanoseconds.
When calling D-Bus methods, three fields are required:
* The bus name, which is what applications own when they
want to expose themselves to D-Bus;
* The object path, which represents a D-Bus object exported
under a bus name;
* The interface, which holds the methods and signals;
While out of pure coincidence all the D-Bus buses have a
matching interface name, it is technically incorrect to assume
that.
Add a new 'interface' field to service_info, and split the bus
name.
GDBus is more and better maintained than libdbus these days. In the
future, a potential Wayland-compatible capture plugin will need to
interact with D-Bus in a way that's way too complicated for libdbus,
and it won't be nice to have both libraries talking to the D-Bus
socket.
Replace the libdbus usage by GDBus. As it turns out, it results in less
code.
DMA-BUF is a widespread Linux buffer sharing mechanism. It is what's
commonly used zero-copy screen sharing by Wayland compositors.
Add a new 'device_texture_create_from_dmabuf' vfunc to gs_exports,
and stub implementations to libobs-opengl. Add a new public method
gs_texture_create_from_dmabuf() that calls this vfunc.
