Due to the refactoring of the update function the separation of data
members only to be accessed from inside/outside the capture thread is
no longer needed.
The old implementation of this function assumed that there would be some
settings that could be changed on the fly without restarting the
capture. That was actually never used for any setting.
Since the helper function also needs to pack/unpack the resolution, the
pack/unpack functions were moved to the helper library and prefixed with
v4l2_ in order to avoid possible collisions.
This was added at a time where the source properties dialog did not
pop up automatically on source creation. Now when the properties are
displayed the first device in the select input will be selected by
default if there was none already specified by the source settings.
This will make the code cleaner and also save one redundant round of
device enumeration.
The capabilities flags that were used previously describe all
capabilities the physical device offers. This would cause devices
that are accessible through multiple device nodes to show up with
all device nodes while only one of the nodes might actually offer
the needed video capture capability.
If the device has more nodes the CAP_DEVICES_CAP flag might be set
in which case the device_caps field is filled with the capabilities
that only apply to that specific node that is opened.
This prevents certain issues I've encountered with devices where they
expect to shut down in a specific thread they started up in, as well as
a number of other issues, such as the configuration dialogs.
The configuration dialogs require that a message loop be present, and
this was not the case previously because everything was in the video
thread, which has no windows-specific code.
Configuration/crossbar/etc dialogs will now execute correctly.
This adds support for dynamic format changes on the fly. Format,
resolution, sample rate, can all now be changed by the current
directshow device on the fly.
On an asynchronous video source, the source resolution is automatically
handled by the core, and set to the resolution of the last video data
that was sent. There is no need to manually specify a resolution.
When setting up the capture, the plugin will now query pulse for the default
format of the specific source instead of the server.
This is useful if a source has different settings than what the defaults are
for the server, e.g. when the source is an output with 5.1 surround sound
and the microphone input is mono while the server defaults to stereo sound.
the pos_x and pos_y variables were somewhat deceptive, because they were
not actually the poition of the cursor. They represented the position
of the cursor's bitmap on the screen, not the position of the cursor.
This implements audio support, allowing not only the ability to capture
the built-in audio from the video device's audio capture pin, but also
the ability to override the default audio with a custom audio device.
The DShowInput::Update function was split up and refactored a bit, as it
was getting a bit large and messy.
This fixes a bug where the pulseaudio plugin always reported
a speaker layout of stereo to obs, regardless of how many channels
pulseaudio actually recorded.
If the default number of channels was different to 2 this would
cause audio distortion.
Originally, I tested the fontconfig code on mac and it was working
swimmingly. However, it seems to be related to the fact that I am using
the ports/homebrew version of fontconfig. Most users do not have that
version, and instead use the system built-in version of fontconfig,
which apparently does not find any mac fonts.. at all. So, this
reverts the mac code to the older mac code we were using to manually
find and associate fonts with font files on the mac.
GCC marks fread as a function that will throw a warning if you do not
use its return value. This is most likely done as a measure to ensure
code security.
