This code assumed that no one would be racing after we stopped the input

during disconnect before we finish closing the video mix.
Instead keep the locks around after stop and use them during close to

This is useful for formats such as 32-bit float PCM which providers
greater flexibility in editing by retaining information that would
otherwise be clipped.
Placeholder sources are created when a plugin providing a source type is
unavailable. Since they're not marked as having audio any audio track
settings for them get lost. With this change we retain mixer information
if the source owns its id to avoid that.
Since 65eb3c0815 we tried to get as close
a sync between audio and video tracks as we could before starting to
send frames to the output.
But in be717dbb2c when multi-track audio
was considered for synchronization it continued to try and line ALL
audio packets up with one video packet. While audio and video packets
are similar size this will work out. But once video packets duration is
smaller than 1/2 audio packet duration this may fail forever. In
practice with AAC's 20-23ms frame duration we can often get tracks
producing frames 5-10ms out of phase. For 60fps video this mostly fine
as 16ms frame duration will cover the gap, but for framerates as low as
100 its possible to fail to synchronize. In practice this is ~50%
for 6 audio tracks and 120fps video on my system, or 100% at 240fps.
The Pulseaudio implementation of audio monitoring was actually listing audio sources.
This change corrects that, so all possible outputs are available.
When creating a group, a newly allocated group `sub_scene` is released
just after calling `obs_scene_add_internal`.
If another thread released the scene-item, which is the sub_scene,
use-after-free might happen.
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.

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.
By adding the range data we can get successful handling of full range
color via custom FFmpeg output. Previously it would always default to 0
which would yield partial/limited output. Without the colorspace info
the output file is correctly tagged, but not undergone the actual
conversion.

As clang and gcc use "default" visibility (as in "not hidden") when
no visibility is specified, all functions are implicitly exported.
When changing default visibility to "hidden", the corresponding symbols
are not exposed anymore and linking fails. This PR updates all
functions signatures that were added in recent commits but not set to
be EXPORTed.
Also makes required OpenGL imports for texture sharing on macOS
mandatory.
When the `pos` variable is non-zero, audio does not get mixed correctly.
This is due to the fact that the `pos` variable was erroneously being
applied to the input rather than the output.
This makes multiple changes to resolve issues with monitoring. We have
added a number of things over time to resolve various issues due to our
misunderstanding of the pulse api and the explicitly wrong pulse api
documentation.
First is removing the prior stream write tracking. Write tracking
was incorrect as pulse sends you the total number of bytes it wants
written at that time and not a incremental, but also this write tracking
is unhelpful since we can just let begin_write signal when we should
stop writing.
Second removing underflow tracking, this sort of worked to detect high
latency sources like vlc which buffer ~1s of data before writing audio
data. It worked because it would grow the buffer in PA until we could
write enough data into it, but it didn't allow us to leverage that
larger buffer because we never paused the PA stream.
To solve the buffering/high latency issue instead start the PA stream
corked and only uncork it once we have enough data to reach the targeted
latency. We also check how much data we recieve from the source and if
it appears to be high latency providing us with much more data than our
target latency we increase the latency to match the source. Fixing the
VLC source issue and resulting in a smooth start to audio instead of
underruns while we play and increase latency.
Finally add some handling for pulses incorrectly documented API. Notably
that begin_write may request more or less data from you so handle both
cases. And stop attempting to use attr.maxlength which is not updated
after set_buffer_attr calls and was always -1, and tlength is just more
appropriate.
old mantis resulting in some changes, still fixed. https://obsproject.com/mantis/view.php?id=1076fixes#7574
New video formats introduced for ProRes 4444 encoding have not been
implemented in function calls used for video decoding, which makes the
switch statements non-exhaustive.
This does not functionally change the status quo (decoding ProRes 4444
files could still be broken because libobs does not explicitly handle
the colour format).
When a variable `pos` became larger than `AUDIO_OUTPUT_FRAMES`, `count`
will get overflowed number. To avoid the overflow, continue the loop
when `AUDIO_OUTPUT_FRAMES - pos` is not positive.
Currently, the X11 display is leaked when the X11 hotkey
platform is destroyed. Fix that by calling XCloseDisplay()
to free it.
Fixes: bcb04bb800 ("libobs: Open a separate X11 connection for hotkeys")
Previously, `custom_size` was checked at the end of the `scene_load`
function. If the scene contained no "items" array, the `custom_scene`
loading code would never be run.
This moves the `custom_size` code above the return statement.
There was quite a bit of conflated usage of mixes (which refers
to raw audio) and encoder counts. This fully separates the two
and makes a distinct separation when iterating over mixes vs
encoders.
OBS has been logging `1 views remain at shutdown` when in reality there
are not technically any views remaining. When views are removed, the
view itself is destroyed immediately, but the mix remains, to be
garbage collected by the graphics thread.
In this case, the view has already been removed, but the graphics
thread has not run an interation and cleaned up the mix, so this
log message appears.
Fixes the issue by checking if a mix actually has an assigned view,
instead of blindly logging existing mixes.
There is currently no way to clear a video_t or audio_t object from an
encoder once applied. `audio_t`/`video_t` objects can be destructed at
any time, and it is dangerous to prevent these object references from
even being cleared.
This does not fix the issue where destroying an audio/video object does
not clear the reference from all subscribed encoders.
Protect `obs_encoder_set_video()` and `obs_encoder_set_audio()` from
being used if the encoder is active. Changing these values while active
is undefined behavior.
Convert `lookup` to upper-case before creating the tree so that later
code does not need to consider the case-insensitivity.
When converting to upper-case, use `toupper` instead of adding 0x20 so
that the behavior is consistent with `astrcmpi_n`.
WidgetInfo::ButtonClicked() is aborting because URL string is not

Because Intel has wonderful code which forces it to run on the iGPU if
there are both an Intel iGPU and an Intel dGPU on the same system, the
adapter index OBS is set to internally will no longer be valid, thus if
anyone calls `obs_get_video_info()` to try to find out what adapter
index OBS is running on, it will be invalid on those computers.
Wonderful.
So, basically, this code here just fixe it so if you want to call
`obs_get_video_info()`, it'll actually have a valid adapter index now,
that way we can reference the adapter index when determining what GPU
we're actually running on without having to like, do anything super
complicated and silly like comparing adapter GUIDs just to figure out
what adapter OBS is actually runing on. I don't want the code to be a
mess anymore.
(I like how in any other situation on the face of the planet, there's no
need to force OBS to run on an integrated adapter. *Normally* OBS
*should* run on the dedicated adapter, that way it can actually capture
games properly. You can probably guess as to why they're forcing it to
run on the integrated adapter rather than the dedicated adapter. But you
know what? Whatever. I don't really care anymore I guess. Just...
whatever. Here we are I guess. Also I was in a bad mood while writing
this just as a disclaimer.)

Since obs-studio switched to Qt6, old plugins linking Qt5 should be
rejected. On Linux system, OBS and it's plugins link the system
libraries so that obs could be crashed by such plugins that links Qt5
when Qt5 functions are called.

Seems to solve lag encountered on the new AMF encoder. The SubmitInput
call in the AMF encoder can occasionally stall for quite a long amount
of time, but most take microseconds, so we can compensate by simply
increasing the buffering (3 to 10 textures).
Using a relative path for the pthread.h header by w32-pthreads breaks
compilation of plugins which include threading.h from libobs (as
w32-pthreads will exist at a different location relative to the
libobs header).
As w32-pthreads (and its include directory) is added to the libobs
target by CMake, the pthread.h header will be found even when using
system header notation.
Fixes https://github.com/obsproject/obs-studio/issues/7155
It seems that the older key still exists on Win 11 and 10 but is always
set to 0, so use the newer to start with and fall back to the old one if
necessary.
Additionally, if the key for HAGS and GameMode do not exist assume
they're on as this is the default on Win 11. On Windows 10 game mode is
also on by default in recent versions.
Also changes "10" to "10/11" just for correctness.
Laptops that render OBS displays on NVIDIA, and display through Intel
have been seen flickering, and we think the driver is not properly
handling swap chain buffers that have been cleared but not drawn to. To
work around this, we use a draw to simulate a render target clear. This
is not as efficient, so hopefully NVIDIA will fix this soon.
This reverts commit 90a409fe58.
Reverts #7077 for now. This really shouldn't be done so close to
release. This crash technically only happens under very niche scenarios,
and the fix seems to have some other potential issues. Prematurely
merged by Jim.
Previously FreeBSD had an optional port that installed /etc/os-release
so it was already available on many FreeBSD systems, but os-release is
now provided by the base system and will be universally available.
Since this was included in things like the inject helper and game
capture DLLs, it added an additional export to those programs. Instead,
simply share the source files directly in the projects that need it.

Some users stream projectors, so don't let them tear. Use the waitable
object to check the flip queue, and only flip if there's space.
Metal and Vulkan can probably perform similar flip throttling once OBS
starts using them.
The spec for nal_ref_idc doesn't indicate that it should be used for
priority like x264 seems to be using it for. NVENC seems to pass
different values, so let's not rely on it.
The new scheme might be naive, but we can iterate on it, and apply
evenly to all H.264 encoders.
Split render_texture and derived fields in obs_core_video into new
obs_core_video_mix struct. Add new APIs to add additional obs_view to the render loop, each with a separate render_texture / obs_core_video_mix.
obs_find_modules2 allows the ability to get the module name in the
callback, and the change to obs_find_modules2 also adds the ability to
find out whether any modules failed to load or not.
Allows the ability to get additional information about the plugin beyond
just whether it's an OBS plugin. For this case, whether it can load,
which is primarily used on Windows and mostly just determines whether it
has an incompatible Qt version.
There's no reason to expose these to scripting. Additional context: More
functions/structures will be added related to loading all modules, and
there's no reason to expose them to scripting either.
Instead of lettings the hotkey thread handle bindings triggered by Qt,
call the callback directly.
By this point, Qt has resolved the modifier state (so no need for the
hotkey thread to do the same), the pressed state is set as well,
the branch takes care of matching the pressed keys.
This also fixes the issue with the hotkey changes introduced by #3914,
which only inject key events when OBS is _not_ in focus (and as such
modifier states are never updated).
Existing code didn't check for possible "empty" linked libraries
(e.g. Threads::Threads when compiler has built-in pthreads support).
Also adds support for compile options defined on linked dependencies.
malloc(0) is implementation defined and almost always a mistake. I
believe we should be more like malloc and treat bmalloc(0) as an error
instead of tying to handle it. For now we can log an error in case 3rd
party plugins are broken, in the future I would suggest this becomes a
crash-worthy error.
Hopefully nothing is actually using this in the first place. As a
library libobs has alignment requirements so we should probably not
allow an application to replace our aligned mallocs with something else.
This also allows more aggressive optimizations inside libobs as the call
can be completely inlined into a libc malloc.
- Changes the default base exponent value to 1.5 from 2.0

true reconnect delay value
Due to a bug in shader parsing, it thinks that because the token
"multiplier" is used here, that the "multiplier" uniform is being used.
This is a workaround for the issue because fixing the parser is probably
going to be much more annoying than just working around the issue for
now.
In bb6787968, we changed the default behaviour to be strict modifiers
and we consider this to be the correct way. There is no need to change
this from code either, since if someone really needs non-strict
modifiers, they can work around it by setting multiple hotkeys.
Having this option in code just means a bigger maintenance cost, so
we'll deprecate the function and remove it in the future.
If obs_core_hotkeys.strict_modifiers is true (new default),
hotkey is triggered only if current key modifiers exactly match
the hotkey definition. If false, legacy behavior is selected.
Adds %s which replaces the keyword with the current unix epoch time.
The %s keyword is common in languages like PHP and Python, and even
some C implementations, but it is not standard so this is a fallback.
However the hotkeys can be configured with right-side modifiers in UI,
the right modifiers did not work when hitting the hot keys.
This is because `query_hotkeys` in `obs-hotkey.c` was querying states of
only left modifiers.
Only warn when the pointer provided to obs_source_release() is
non-NULL. In some custom usages of libobs, libobs may be freed before
OBS* smart pointers (like OBSSource) are destructed, leading to a
misleading warning if the pointers have already been cleared with
nullptr.
Previous behavior is basically:
- Clear OBS* pointers with nullptr
- Unload libobs
- Those smart pointers that were cleared will still call
obs_source_release() on destruct
- Warning appears
Add comparison check so that NaN is caught.
Comparisons with NaN always result in false.
NaNs cause problems later in audio encoder.
