Probably long time coming, but when the user changes their default audio
device in Windows sound settings, OBS will now detect it and change the
audio device automatically to the new device if it was set to use the
"Default" device.
Add exchange functions to alias the poorly named set functions.
Add store without reading previous. Faster on non-x86 processors.
Add compare-exchange that updates previous to avoid redundant fetch.
On Windows, load bool without conversion from char.
On Windows, load using mov with compiler barrier. Still seq_cst.
On POSIX, use GCC __atomic builtins.
df4eb82 fixed a bug that caused source audio timestamps to perpetually
lag. However, there is a deeper issue where after we reach max
buffering, lagging sources make OBS's entire audio pipeline fall over.
These may be corrected by later code, but still cause global audio
glitches at best. Persistent problems, as prior to df4eb82, cause audio
to fail entirely.
The root cause is that OBS's audio mixing tree cannot deal with
timestamps prior to the current audio tick. Intermediate mixing stages
assume that the lowest incoming timestamp is the base of the current
tick, and mix accordingly. This propagates lagged timestamps up the
tree, where at the top level mix_audio will drop the source entirely -
which at this point is a transition covering all inputs, thus glitching
audio globally. Where extra buffering can cover the slip, the entire mix
gets retried and the error corrected, but when the global buffer
duration is maxed out, it makes it to the output.
The solution is to catch laggy sources immediately after rendering, and
drop audio to bring them back in sync, or mark them pending if not
enough audio is available. This ensures later mixing stages are not fed
with out of sync timestamps.
This improves the ignore_audio code to only drop as much audio as
needed to bring the source back in sync, and moves its call to
immediately after source audio rendering.
This adds additional capture presets, including 3840x2160 and
1920x1080, in addition to the preset "High." These are guarded with
a runtime check using the @available() keyword for macOS 10.15+.
Bug is caused by the internal connection variables not being reset on
reconnect, leading OBS to both be unable to parse valid packets from and
send valid packets to the remote end. This commit splits RTMP_Init off
into a new RTMP_Reset function, which resets these internal variables
without re-initing the rest of the library. The original RTMP_Init
calls the new function, perfectly preserving the old behaviour while
adding a new reset function to address the issue with.
Fixesobsproject/obs-studio#2865
While the current code only ever calls try_connect() with the input
argument 'device' in the range of 0 and MAX_DEVICES, this adds a check
to ensure that future code does not break the following sprintf.
In addition, use snprintf instead of sprintf to ensure that if anything
breaks, the sprintf does not lead to memory corruption. Again, the new
check should already make sure of that, but the additional effort of
using snprintf instead of sprintf is so low that it is worth to have a
little more security in the future.
Removes prior attempt to expose libcaption headers which really shouldnt
have public. This instead moves the obs-internal include out of the
public obs-scene.h and into it's implementation.
Add display capture support via winrt_capture_init_monitor. Almost all
of the existing window capture code is reused.
Rename winrt_capture_init to winrt_capture_init_window for symmetry.
After cleaning up the native flags in various places, and disabling
making sibling of native widgets native, BrowserDock was left in an
inconsistent state, since it requires being native for CEF to work
properly.
Make BrowserDock native.
Some widgets are marked as native unnecessarily. Native widgets are
a bit more involving than regular ones, so remove this flag.
Original patch by David Edmundson <kde@davidedmundson.co.uk>
Native windows really only make sense for previews. They can be a new
xcb_window or a wayland subsurface.
For historical reasons setting a widget to native will also affect
ancestors. Qt will still draw them as part of the parent as they are
never mapped, but a window is nonetheless created.
This is especially problematic on wayland as then the subsurface is
parented to an unmapped window.
This default behaviour can be turned off. Now only the native widgets
(the video previews) are actually native.
