(Note: This commit also modifies UI)
Instead of using signals, use designated callback lists for audio
capture and audio control helpers. Signals aren't suitable here due to
the fact that signals aren't meant for things that happen every frame or
things that happen every time audio/video is received. Also prevents
audio from being allocated every time these functions are called due to
the calldata structure.
(Note: test and UI are also modified by this commit)
API Changed (removed "enum obs_source_type type" parameter):
-------------------------
obs_source_get_display_name
obs_source_create
obs_get_source_output_flags
obs_get_source_defaults
obs_get_source_properties
Removes the "type" parameter from these functions. The "type" parameter
really doesn't serve much of a purpose being a parameter in any of these
cases, the type is just to indicate what it's used for.
OSX has an annoying feature called "BeamSync", which on later versions
of OSX is always on. For whatever reason, Apple devs decided to force
this feature to always be on, so applications must always render with
v-sync regardless of what they set their swap interval to.
This issue would cause syncing to the vertical refresh for each
additional active display, and wouldn't allow rendering above the
current refresh rate. This caused major rendering stalls and prevented
video frame timing from being accurate.
This fixes the issue by using an undocumented set of functions to
disable BeamSync. Note that because this is an undocumented method of
working around the issue, its existence cannot be guaranteed. If the
functions no longer exist for whatever reason, it will safely do
nothing.
These really are advanced options that users shouldn't need to change
normally, so moving them to advanced makes sense, and keeps them away
from users who don't know what they're doing.
If the base resolution is set to an invalid resolution, it would cause
the output resolution to automatically change to an invalid resolution.
After the invalid resolution was set for the output resolution, it would
stay at that invalid resolution.
This fixes it so it always tries to find the output resolution closest
to what was last actually set or actually edited.
When right-clicking items in the preview window and getting context
menus for them, it would often make the wrong scene item be associated
with the context menu because of the fact that it was using
QListWidget::currentItem instead of querying the actual selected list.
You must query the actual selection list via QListWidget::selectedItems
because QListWidget::currentItem does not work properly for
multi-selection list widgets.
If a global audio device is disconnected or for whatever reason is no
longer available when audio settings is opened, it will erroneously
select index 0 of the combo box ("Disabled") by default because it can't
find it in the combo box. This fixes that issue by making it insert an
item in to the combo box specifying that the previously available audio
device is no longer available, and properly preserving the user's
settings.
Some streamers would accidentally hit start/stop streaming, which on
certain services would send out mass emails to all their followers.
This just adds options to general settings to optionally enable dialogs
that confirm whether to actually start/stop streaming when the button is
clicked.
Because of the patch that removed the "user sources list" in libobs
(70fec7ae8), obs_enum_sources will now enumerate the global audio
sources, where it didn't before. In the advanced audio properties
dialog, before the patch I had to use code to manually include them, but
I neglected to remove that code when I made that patch, so it would
cause them to be added more than once. This just removes that code.
When you assign a menu to a normal QPushButton, it becomes a button that
only allows you to have a menu. This class lets you click the button
and have a menu at the same time.
Prunes code used to workaround libobs "user sources" (such as
sourceSceneRefs) and instead simply holds its own references and saves
sources it chooses with obs_save_sources_filtered.
(Note: This commit breaks UI compilation. Skip if bisecting)
Ensures that a reference is kept until the signals associated with that
reference are disconnected.
Having sleep or screensavers inhibited at all times was causing some
annoyances for people. Sleep/screensavers are now only inhibited when
the program is active or when a projector is open.
Fixes the following warning:
warning C4505: 'operator ==' : unreferenced local function has been
removed
This function actually is used despite this warning, so the only way to
get rid of the warning is to disable the warning itself in this
particular case.
Currently creating new sources can cause a deadlock:
OBSBasicSourceSelect locks the scene mutex when adding a new source
(required to add invisible sources), and later OBSBasic tries to
lock the graphics mutex (via CreatePropertiesWindow); meanwhile the
graphics thread is holding the graphics mutex and tries to lock each
scene as it renders them, resulting in a (non-obvious from the code)
lock ordering conflict.
Moving the CreatePropertiesWindow call out of the locked scene mutex
restores the previous lock ordering; in addition, the requirement
for keeping sourceSceneRefs for opening that initial properties
window is removed
API removed:
--------------------
gs_effect_t *obs_get_default_effect(void);
gs_effect_t *obs_get_default_rect_effect(void);
gs_effect_t *obs_get_opaque_effect(void);
gs_effect_t *obs_get_solid_effect(void);
gs_effect_t *obs_get_bicubic_effect(void);
gs_effect_t *obs_get_lanczos_effect(void);
gs_effect_t *obs_get_bilinear_lowres_effect(void);
API added:
--------------------
gs_effect_t *obs_get_base_effect(enum obs_base_effect effect);
Summary:
--------------------
Combines multiple near-identical functions into a single function with
an enum parameter.
Use explicit UTF-8 byte sequence for the "no-break space" character.
Prevents issues with certain editors, and fixes the following compiler
warning on Visual C++:
warning C4819: The file contains a character that cannot be represented
in the current code page (X). Save the file in Unicode format to prevent
data loss
(Jim) For some reason a character outside of the standard ASCII
character set was used in this source file. "Eight Spoked Asterisk",
Unicode character 0x02733. Non-ASCII characters should probably not be
used directly in source files due to potential character encoding
issues that can occur depending on the operating system and compiler.
Closesjp9000/obs-studio#485
Note: This functionality should probably be considered as a temporary
solution. Ideally, sources should not be visible on creation until the
user presses "OK" in the initial properties dialog. Also, the problem
of initial visibility can additionally be solved by implementing the
preview/program functionality. Once preview/program is implemented the
need for this patch will be negated, and the option should probably be
removed.
Closesjp9000/obs-studio#483
RemoveScene would always remove the currently selected item from the
scenes list, even if that item didn't reference the actual scene being
removed; finding the proper item via its OBSRef fixes this issue.
How to reproduce the original issue:
Create two scenes "a" and "b", set a hotkey for switching to scene "a",
select scene "b" and press the remove scene button, then while the
confirmation dialog is up press the hotkey while the UI is out of focus.
The active scene should have switched to "a", while the dialog still
displays "b" as its target; now confirm the removal of "b". Note how "a"
was removed from the scenes list instead.

This reverts commit 35b2ce565a2b90909e2b94da5f28de4bb3a87ff0.
There is far too much potential for issues to occur if the first-time
start creates a display capture by default on linux and windows.
Display capture on windows laptops will not be guaranteed to capture
properly, leaving the user with a blank screen. Display capture on
linux downloads its image off the graphics processor, so it's quite
inefficient to have on by default.
When an encoder has been removed (such as CoreAudio) and the audio
bitrates currently configured no longer are available to the current
audio encoders anymore, it would cause GetAACEncoderForBitrate to return
false with no encoder available.
To fix the issue, instead just choose the closest bitrate relative to
the current bitrate (rounded up).
After some more testing, utvideo not only gives better encoding
performance, but also better compression and better decoding
performance. It's pretty much superior all around over huffyuv.
So certain high-profile individuals were complaining that it was
difficult to configure recording settings for quality in OBS. So, I
decided to add a very easy-to-use auto-configuration for high quality
encoding -- including lossless encoding. This feature will
automatically configure ideal recording settings based upon a specified
quality level.
Recording quality presets added to simple output:
- Same as stream: Copies the encoded streaming data with no extra usage
hit.
- High quality: uses a higher CRF value (starting at 23) if using x264.
- Indistinguishable quality: uses a low CRF value (starting at 16) if
using x264.
- Lossless will spawn an FFmpeg output that uses huffyuv encoding. If a
user tries to select lossless, they will be warned both via a dialog
prompt and a warning message in the settings window to ensure they
understand that it requires tremendous amounts of free space. It will
always use the AVI file format.
Extra Notes:
- When High/Indistinguishable quality is set, it will allow you to
select the recording encoder. Currently, it just allows you to select
x264 (at either veryfast or ultrafast). Later on, it'll be useful to
be able to set up pre-configured presets for hardware encoders once
more are implemented and tested.
- I decided to allow the use of x264 at both veryfast or ultrafast
presets. The reasoning is two-fold:
1.) ultrafast is perfectly viable even for near indistinguishable
quality as long as it has the appropriate CRF value. It's nice if you
want to record but would like to or need to reduce the impact of
encoding on the CPU. It will automatically compensate for the preset at
the cost of larger file size.
2.) It was suggested to just always use ultrafast, but ultrafast
requires 2-4x as much disk space for the same CRF (most likely due to
x264 compensating for the preset). Providing veryfast is important if
you really want to reduce file size and/or reduce blocking at lower
quality levels.
- When a recording preset is used, a secondary audio encoder is also
spawned at 192 bitrate to ensure high quality audio. I chose 192
because that's the limit of the media foundation aac encoder on
windows, which I want to make sure is used if available due to its
high performance.
- The CRF calculation is based upon resolution, quality, and whether
it's set to ultrafast. First, quality sets the base CRF, 23 for
"good" quality, 16 for "very high" quality. If set to ultrafast,
it'll subtract 2 points from the CRF value to help compensate. Lower
resolutions will also lower the CRF value to help improve higher
details with a smaller pixel ratio.
