Add a new helper library to handle the mouse cursor using xcb.
Since porting the old library without either keeping legacy code or
breaking the api would have been non-trivial, this is added as a
completely separate implementation. Once all code is ported over to
use this library, the old one can be removed.
This causes x264 to use the currently set color space and color range
of the video media. This helps prevent issues with decoding where the
colors wouldn't look right due to the fact that these settings were
never specified to x264, and prevents darkness and brightness from
looking washed out due to a potentially incorrect color range.
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.
These functions allow the safe hooking of windows functions,
specifically windows API functions that may or may not have built-in
machine code to help aid in reverse chain hooks.
If a new hook is applied to an existing forward hook, that hook will be
preserved to prevent that new hook's data from being removed
unintentionally.
Hopefully with all these precautions this will reduce the likelihood of
crashes and abnormal hook behavior, while allowing existing hooks to be
preserved, and allowing new hooks to be applied.
This fixes a bug where if INCLUDE_MINIMIZED was set and the window size
was (0, 0), the window would still be excluded from the resulting list
that was created.
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.
When getting the class/title/exe of a particular window handle in the
build_window_strings function, always set the class/title/exe pointers
to null to prevent any potential references to invalid values if any of
them do not happen to be set for whatever reason.
This adds a property to the source properties which lets the user
specify the X server to capture from. Since this is probably something
thats only useful under certain circumstances it is implemented as
an advanced setting which is only shown when the corresponding option
for advanced settings is checked.
This moves the code to start/stop the capture to respectively named
function in order to clean up the update function.
This means that the capture is stopped/started whenever the settings are
changed. While this increases overhead for some settings, this will also
enable future settings that require a full restart of capture process.
This adds the screen id from the source properties to the source
struct and changes the geometry function to use that value instead
of requiring the settings object of the source.
On windows, carriage return characters are used along with line feed
characters. When the carriage return is used, it's rendered as a space.
This removes carriage returns from strings before rendering them via
freetype.
Doing this in the expression will cause it to execute the function every
time the expression is evaluated, which is needless cycles wasted.
Instead, call wcslen before the loops begin.
If FFmpeg's experimental aac encoder is used, this changes the cutoff
frequency to better values in order to try to help make up for the
inherent lack of encoder quality a bit. If FFmpeg is compiled to use
another encoder by default, these settings will not be applied.
XComposite, which is currently our only capture method for windows,
doesn't handle X border width. This works in a lot of cases but anytime
there's a border, a bug occurs where the lower right is clipped. This
patch has two goals:
1) To position and size the capture texture correctly in accordance to
the border.
2) Adds a configuration option to allow people to toggle it (which in
most cases will simply do nothing) with a default of not including it.
Some applications defer loading OpenGL until after they are visible as
running applications, which causes SyphonInject to not install a server
on the first try (e.g. Minecraft does this)
In some cases the actual application (bundle identifier) would get
overwritten with a wrapper application bundle identifier when the
application names matched (this happened with e.g., Minecraft)
This adds helper function to disable/enable all properties which is
used in the device selected callback to enable/disable the properties
when the selected device is available/unavailable.
This adds some code to the device enumeration that checks if the
currently selected device is present. In case it is not it will
add the device but disable it.
This moves the calls to the property modified functions so the old
handler can close the device. Otherwise this would cause the device
to be opened multiple times.
This replaces the var in the source struct that are handling the
timestamp offset with a local one in the capture thread.
This change is mostly to make the code more readable.
This moves the enabling/resetting of the file descriptors inside the
capture loop so it is done before each select call. Why this even worked
before is unclear, but doing it the *right* way seems to reduce latency.
