Attempt to schedule shared texture copies against the command queue that
the game's swap chain uses to try to reduce artifacts. The heuristics
for obtaining the queue are not perfect, so provide a toggle to use the
previous behavior.
Modify game capture shared textures to be typeless if they could
potentially need SRGB and non-SRGB views in the future.
These capture APIs have been updated: D3D 10/11/12, Vulkan.
D3D8 capture does not use shared textures.
D3D9 and GL interop do not support typeless textures.
The new game capture DLL should be compatible with old versions of OBS.
Also removed a lot of dead code around pointless SRV/RTV support.
For game capture, hook DXGI release function to release D3D objects if
the related swap chain is also being destroyed.
An added bonus is that the game capture hook will handle swap chain
recreation for applications that don't use ResizeBuffers.
Checks the hook version to ensure compatibility with hook DLL. It's
unlikely it'll ever be necessary to increment the hook version, but this
is just a precautionary thing that allows a hook DLL to make sure it's
rejected by an older OBS version if needed. Again however, very
unlikely that the major version will ever be incremented.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
This detects whether the target process is a UWP process, and then uses
the open_app_* functions for mutexes/events/mapping. Also slightly
refactors named object open functions.
All named objects (including file mapped shared memory) need to be
created within the hook itself due to the fact that UWP programs cannot
access named objects outside of the UWP process.
Because shared memory needs to be created within the hook, the capture
loop cannot start until the shared memory has been filled with valid
data. Creating an additional "initialize" event fixes this issue.
Additionally, changed the way that named kernel objects are
opened/created. Before, there were functions that would first try to
open named objects and then implicitly create them if opening failed
(assuming that if the hook didn't create it first, game capture would),
now it's been changed so that you can only either explicitly open or
create.
To check to make sure game capture is still active in the capture
program, it currently uses a named event, and then it checks to see if
that named event exists. However with UWP programs, you can't open a
named event outside of the UWP process. FindWindow on the other hand
does work, so instead of checking to see if a named kernel object
exists, create a window and check to see if that window exists.
The virtual address table values for Reset/ResetEx can sometimes point
to functions that are in libraries outside of D3D8.dll and D3D9.dll, and
will cause a crash if used. Instead, just hook Reset/ResetEx when one
of the Present* functions are called.
This header contains global defines, structures, and helper inline
functions for the graphics hook that will be shared between game
capture, the hook, and the get-graphics-addrs helper application.
