I originally had it set the color space and color range in the video
info callback, but I forgot that it's a function that's called after the
encoder is initialized. You can change the color space and color range,
but you have to reconfigure the encoder, and there's no real reason to
do that.
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).
Allow the user to select whether to buffer the source or not. The
settings are auto-detect, on, and off. Auto-Detect turns it off for
non-encoded devices, and on for encoded devices.
Webcams, internal devices, and other such things on windows do not
really need to be buffered, and buffering incurs a tiny bit of delay, so
turning off buffering is actually a little better for non-encoded
devices.
The 'sent_headers' member variable of the FLV output would not be reset
when the output was restarted, causing important data to not be written,
thus creating an invalid FLV file.
On i3wm, windows aren't unmapped when switching away from a window's
workspace, but it does cause OBS to lose the capture. Because
switching back will not trigger a MapNotify, the capture fails to
restart unless you resize or move the window (ConfigureNotify). An
Expose event is fired by the wm, however, so catching this correctly
restarts the capture.
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 adds support for the AverMedia C985 encoder (which is available on
C985 capture cards) as well as the C353 hardware encoder (which is
currently available on the X99S Gaming 9 motherboards).
These encoders have some limitations, such as limited resolutions
(1280x720 and 1024x768), a max GOP size of 30, and the encoder format
only supports YV12, which requires conversion if the current output
format isn't the same. The C985 and C353 encoders seem to be pretty
much identical, although it seems like the C353 has a bit more efficient
encoding.
I don't believe these are really suitable for streaming, as they do not
really have the encoding efficiency needed to stream at lower bitrates,
and seem to only support variable bitrate. However, for recording these
encoders are quite nice to have available, and work quite well.
The main module code was originally all packed in to the win-dshow.cpp
file, which isn't exactly ideal or clean if one wants to add other
things to the module as a whole.
Previously, due to a bug in libdshowcapture, the NV12 format was
actually being used for YV12 erroneously, and no actual support for YV12
existed. This fixes the bug with NV12 and adds support for YV12.
Waiting for the first packet to arrive before sending the headers helps
prevent issues with certain types of encoders that may not get their
header/SEI until the first packet has been received.
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.
