Previously enabling and disabling bandwidth testing in a certain order
lead to the parameter being included in the stream key that is saved to
disk, making it impossible to disable the bandwidth test later on.
By doing this properly and using string concatenation instead of
modifying (appending to) the key_ value this will no longer happen.
All UI elements are accessible through the obs frontend api via
obs_frontend_api_get_main_window, except for the tray icon and its
elements. This commit adds an obs_frontend_api_get_system_tray function
which returns the pointer to the QSystemTrayIcon cast to void (much like
the QMainWindow pointer for the main window).
This solves the issue of users who close the primary dock widgets and
can't figure out how to get them back, who for whatever reason choose
not to read the message box when closing dock widgets that tells them
how to get it back. The users can still hide the primary dock widgets
via the View menu, but they can no longer close them via the [x] button
on the dock widget. This change does not apply to secondary dock
widgets, such as a chat window, stats, etc.
Closesobsproject/obs-studio#1804
Fixes a crash that can happen if you try to use the settings window
while in an even subloop, or if you try to close OBS while in an event
subloop. Continually retries (defers) the actions every one second
until the subloop has finished.
This new scale filter computes pixels by weighing the coverage area of
source pixels over the target pixel. This algorithm works well for both
upsampling and downsampling, but was mainly designed to upscale
high-quality low-resolution sources like RGB/HDMI retro consoles. I've
heard of people using odd workarounds like scaling up to very high
resolutions before scaling back down to preserve pixel shartpness. This
algorithm directly addresses this use-case in a much more direct
fashion.
The Area scale filter does a better job of preserving the thickness of
thin features than the Point filter.
The Area scale filter does not look at source pixels that lie outside
of the target pixel, leading to a much sharper image than Bilinear,
Bicubic, and Lanczos filters.
This filter should interpolate pixels in linear space, but OBS is not
equipped to do that at the moment.
libobs: Add GPU effect, and wire up scene serialization.
obs-filters: Add Area as an option for scale_filter.
UI: Add Area as an option for both scene items, and canvas downscaling.
Users don't realize that dockable windows can be closed (hidden) and can
be shown again via the View menu. This adds an explicit warning when
the user first closes a dockable window for their first time. In future
versions, this should be changed to a dialog box with a "Do not show
again" checkbox.
