UI supplied per scene hotkey to allow switching between scenes; this
has to be done in the UI since it's up to the application to define
what exactly "changing/selecting a scene" means (changing the output
of channel 0 may not be enough for other applications)
OBSHotkeyEdit is similar to QKeySequenceEdit, except less terribad on OSX, while
OBSHotkeyWidget provides a container that automagically encapsulates multiple
bindings per hotkey
OBSHotkeyLabel in combination with OBSHotkeyWidget provides mechanisms for
dealing with hotkey pairs (see upcoming usage in window-basic-settings.cpp)
When a reconnect is occurring, the user doesn't really know that the
program is waiting to reconnect to the server or not, nor does the user
know how many seconds are remaining until that next attempt. This will
show the reconnect timeout countdown as it's occurring.
NoFocusFrameStyle was meant to disable focus frames around the scenes/sources
list (on OSX); unfortunately it also removed focus frames from controls that
should have focus frames like input boxes in the settings window
Non-NV12 video formats are primarily intended for recording. For
streaming, if the libobs color format is not set to NV12, it's likely
that the video frames will have to be converted to NV12, which will use
extra CPU usage. Due to that fact, it's important to warn the user of
that potential extra increased CPU usage that may be required when
streaming.
This allows using NV12, I420, or RGB output video formats. This option
will set what obs itself outputs frames as.
It's important to note that this is only ideal for specific FFmpeg
encoders that support the desired video format; for example, if you use
RGB and use the huffyuv encoder, huffyuv will now properly output in RGB
instead of YUV NV12/I420.
I420 is useful for eliminating the NV12->I420 conversion for the
AVerMedia encoders, as AVerMedia encoders only support I420 input.
A second even more important note about RGB is that if the encoder does
not support the format you are using, it will be converted on the CPU to
a format that the encoder supports as it's encoded; so for example
setting the obs output format to RGB and then using x264 will be futile
and end up using needless amounts of extra CPU than if you just had obs
set to NV12, which is the most common and ideal format for x264.
In the future, native output of other YUV formats might be implemented
(such as YUV 4:2:2).
When this class is used in conjunction with a QSlider control, allows
direct setting of the slider handle position when clicking in an area
other than the slider handle. The default QSlider handle behavior is to
step towards clicked position.
