win-capture should not postfix .lib to psapi.
The graphics hook also requires psapi when linking.
Also change some link libs as mingw-w64 libraries are not postfixed
.lib.
Uses the output duplicator API in order to get a high performance
monitor capture on windows 8+. This is actually designed to be
interchangeable with regular GDI-based monitor capture (uses the same
source id).
This adds the windows version of game capture.
New features:
- An option to hook any fullscreen application automatically (that
doesn't have borders) so that no specific window configuration is
required. Definitely a sorely needed feature
- An option to force memory capture for the sake of compatibility with
things such as SLI, multi-adapter setups (usually laptops), as well as
the ability to be used with the OpenGL renderer
- An optimization option to force scaling on the GPU before texture
transfer, reducing the transfer bandwidth (which is especially
important for compatibility capture)
- An optimization option to limit framerate to the current OBS framerate
to improve capture performance (mostly useful for compatibility
capture)
- An option to capture third-party overlays (such as steam)
- Logging improvements, game capture log will now be sent via pipe
instead of written to a separate file, making diagnosing problems a
little bit easier
This library is a completely refactored and rewritten version of the
original graphics hook. The code is more clean, readable, and has a
variety of new features, such as scaling and forcing memory capture.
Currently, only D3D9, 10, and 11 are implemented. (This commit may be
updated on this branch)
Before, game capture would find addresses to important graphics
functions by creating a graphics context for the desired API inside of
the hook, and then find the function addresses that way.
The big problem with that is that the context could often cause the
hooked application to crash, especially if another hook was active.
This bypasses that entire need by a simple console application that
creates the contexts, finds the hook address offsets and then returns
them via console output.
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.
This adds obfuscation functions primarily for use with GetProcAddress.
This takes an obfuscated string and uses a simple integer key to
de-obfuscate it to the intended function name string, which is then
loaded dynamically using GetProcAddress.
This is typically only used with functions such as OpenProcess,
SetWindowsHookEx, and the like, which can often be misinterpreted the
wrong way by security programs if those strings are found within the
strings segment of a scanned executable.
Because other capture methods may end up needing to share this code,
separate the window finding source code to window-helpers.c and
window-helpers.h.
This include a function to fill out a property list with windows, a
function to find a window based upon priority/title/class/exe, and a
function to decode the window title/class/exe strings from a window
setting string.
Now that we have the priorties window in we can finally be able to
select windows for capture source such as window capture. Only took
about an hour or two to write.
Also, fixed some depednency issues on winmm.lib with obs-outputs
- Implement windows monitor capture (code is so much cleaner than in
OBS1). Will implement duplication capture later
- Add GDI texture support to d3d11 graphics library
- Fix precision issue with sleep timing, you have to call
timeBeginPeriod otherwise windows sleep will be totally erratic.
