Passing the parent of a QLayout sets it directly as the top-level layout
(as per the QLayout docs). This is obviously not what is intended here.
Luckily it doesn't even work since the main window of course already has
a layout which would need to be explicitly removed before, but it makes
Qt yell at us for trying.
Currently, the manifest URL on Flathub Beta website points to the
deprecated manifest hosted on Flathub. The flathub::manifest key
is undocumented attribute that will update the website to use the
proper location.
This key will not affect appstream other than providing enough
information to the Flathub website.
Adds a NtMapViewOfSection hook which we can use before DLLs are loaded
to decide whether to abort the process. This is useful for blocking
known problematic DLLs that cause crashes. In addition, the PE timestamp
can be checked to block only older DLLs such as older versions of Vtuber
virtual cameras with known deadlock bugs.
A simple counter of each DLL is used for logging purposes. Since DLLs
can be blocked at any time, the output is only logged on exit of OBS.
All presentation time stamps are rounded to whole seconds during the
conversion from nanoseconds to seconds, because of the immediate cast
to `int64_t`. This results in the same presentation time stamp being
send to consumers for a whole second.
In previews/live streams this isn't super visible as last frame is
often assumed to be the newest and the stream is updated. It's more
problematic when recording since APIs like Apple's AVFoundation don't
allow duplicate presentation time stamps or it can look like frames are
produced in huge bursts once per second.
In this PR `CMTimeMakeWithSeconds` is used instead of `CMTimeMake` to
make sure the conversion is done correctly and simplify the calculation
we have to do a little.
The `fillFrame` method of the mac-virtualcam plugin is creating samples
directly using the value from `mach_absolute_time()` as `hostTime`.
This assumes this value is in nanoseconds, while it is in fact in mach
tick units. On Intel Macs mach tick units will be exactly 1 nanosecond
resulting in valid values, but on Apple Silicon macs this is no longer
the case.
This results in sample buffers with the placeholder image that have
much lower presentation time stamps than the samples containing content
produced by OBS. In previews/live streams this shows due to the last
content sample being shown frozen until the whole buffer is filled with
samples containing the placeholder image. Applications recording the
video stream are even more confused and crash or record videos with
wildly incorrect lengths.
In this PR `clock_gettime_nsec_np` is used to convert from mach tick units
to nanoseconds. This will make sure the `hostTime` value is correct on
both Apple Silicon and Intel macs. Making sure we produce stable
presentation time stamps from the virtual camera plugin at all times.
When not using binary mode (i.e. text mode) CRLF will be converted to
LF, which means that the size provided by tellg() is no longer correct,
and reading prematurely hits an EOF and sets the fail bit.
If OBS is set to minimize to system tray on startup and studio mode is
enabled, the preview would be disabled when showing OBS, if the preview
in non studio mode was disabled.
If the recording path is left empty in Settings, a leak can occur in
window-basic-stats.cpp because a bmalloc is called for a size 1.
This fixes the leak by checking against the path in the
os_get_free_disk_space function.

If the scene item was rotated greater than 45 degrees, and flipped
vertically or horizontally, the spacing helpers would be drawn
incorrectly. This fixes the issue by checking the scale before
the rotation, instead of after.
fstream is not thread-safe and the act of writing the string and the
newline are two separate operations which could execute concurrently in
multiple threads, resulting in lines joining together followed by two
newlines. Due to the presence of a static mutex, this also removes
inline on the function.
It was possible to set the encoder to scale the video to the same size
as the output, resulting in unnecessary passes through swscale and
skipping hardware encoders. This was a common user error in Advanced
Output mode where they would tick the rescale box but leave it at the
same resolution as their main output.
