Limits similar log entries (determined by a simple hash function that
sums the characters) to certain number of lines in a row. When a
different log entry occurs, it resets the repeat check and logs how many
times the last message was repeated.
Due to certain design changes for delay, it's better to simply determine
whether outputs are active via booleans rather than an activeRefs
variable, which could get decremented more than once if say, the signal
for stopping the stream gets called more than once for whatever reason
(which may happen in the case of delay due to the way delay works)
Replaces all the json/config loading/saving functions with safe
variants to reduce the chance of potential file corruption as much as
possible.
Also does a minor refactor of json writing by using
obs_data_save_json_safe for writing json files instead of manually using
obs_data_get_json and os_quick_write_utf8 each time.
API Changed:
---------------------------
From:
- bool obs_startup(const char *locale, profiler_name_store_t *store);
To:
- bool obs_startup(const char *locale, const char *module_config_path,
profiler_name_store_t *store);
Summary:
---------------------------
This allows plugin modules to store plugin-specific configuration data
(rather than only allowing objects to store configuration data). This
will be useful for things like caching data, for example looking up and
storing ingests from remote (rather than storing locally), or caching
font data (so it doesn't have to build a font cache each time), among
other things.
Also adds a module-specific directory for the UI
If a user was using FFmpeg output before pathc 0.12.0, they had to type
in the full file name to the FFmpeg output URL/Path box, which isn't
exactly compatible with the new settings.
This changes each profile's config file so that the FFmpeg output
detects whether files are used, and then extracts the file's directory
and extension and sets them accordingly to make it compatible with the
new FFmpeg file output handling.
This changes the way the advanced output section's FFmpeg output
settings work by allowing the user to select whether they want to output
to a file or output to a URL, and makes it so file names are
automatically generated like other recording outputs.
If they choose to output to a file, it'll only require an output
directory similarly to how other recording outputs work. They can
select a directory to output to rather than being required to type in a
full path and filename; the filename is automatically generated. The
extension is also automatically retrieved from libff depending on the
format selected.
Otherwise if they have Output to URL selected, it'll show a simple edit
box where they can type in the target URL.
Apparently using QPointer container for the QObject being given to the
connect function makes it so it can't find the actual function to use.
I'm guessing this is incomplete functionality or a bug that existed in
GCC 4.8. Doesn't happen in 4.9+.
When settings the base resolution, try to find the closest output
resolution to the old output resolution, and use that for its value. If
the aspect ratio is about the same, then don't modify the value. If the
aspect ratio is significantly different, then find the closest
approximation while keeping with the new aspect ratio.
This particular issue has been an annoyance for quite some time.
Due to all the threads in libobs it wouldn't be safe to make that
parameter reconfigurable after libobs is initialized without adding
even more synchronization. On the other hand, adding a function to set
the name store before calling obs_startup would solve the problem of
passing a name store into libobs, but it can lead to more complicated
semantics for obs_get_profiler_name_store (e.g., should it always return
the current name store even if libobs isn't initialized until someone
calls set_name_store(NULL)? should obs_shutdown call
set_name_store(NULL)? Passing it as obs_startup parameter avoids
these (and hopefully other) potential misunderstandings
Fixes a minor bug introduced by the windowless graphics context merge.
When setting a new base resolution, it would not recalculate the preview
size, and the preview would display the wrong size until the main window
was resized by the user. This patch makes it so that it calls the
recalculation function when the base resolution is changed to prevent
that from happening.
Now that we aren't dependent upon a window for our context, we can
safely move the obs context creation/destruction to obs-app.cpp, and use
the OBSContext helper class to automatically shut down obs.
(Non-compiling commit: windowless-context branch)
Now that all obs_display related code has been moved to OBSQTDisplay,
we can prune a whole bunch of boilerplate code that had to be repeated
for the displays of each window.
Affects:
- Properties
- Filters
- Interact
- Projector
(Non-compiling commit: windowless-context branch)
Gets rid of all functions/data related to setting up the main preview to
be associated with obs_reset_video and instead uses OBSQTDisplay for the
main window display (thus associating it with an obs_display object).
(Non-compiling commit: windowless-context branch)
This makes it so that OBSQTDisplay now uses/controls an obs_display
object directly (rather than having the owner have to associate an
OBSDisplay with it). It was separated before because the main window
for the basic UI would was using the "main preview" stuff before the
windowless context and had to be handled differently, so you couldn't
just associate an obs_display object with OBSQTDisplay, meaning that all
"secondary" previews such as properties/filters/etc had to handle the
obs_display alone, which caused a lot of needlessly duplicated code.
Also adds a DisplayCreated signal to allow owners to be able to add
callbacks and such on creation of the actual obs_display context.
Found via clang-3.6, actual warning:
window-basic-main.hpp:406:14: warning: 'GetProfilePath' overrides

[-Winconsistent-missing-override]
Adds Microsoft Media Foundation AAC Encoder that supports
96k to 192k bitrates. This plugin is only enabled on Microsoft
Windows 8+ due to performance issues found on Windows 7.
I broke the save that happens on exit by making all project saves put on
the message queue. The save on exit would put the save on to the
message queue, then by the time the save occurred obs would already be
shut down.
This just calls the save function directly rather than deferring it to
the message queue.
This temporarily fixes an issue where potential (for whatever reason)
stray sources that aren't associated with any scenes could be saved and
then persist with the save data on load.
SaveProject calls obs functions that locks certain mutexes, and because
I made it so that SaveProject was being called inside of certain signal
handlers (which could already be locked in other mutexes), it could
cause a mutual deadlock with other threads.
This fix puts the main project saving code in to SaveProjectDeferred,
then pushes it on to the Qt message queue to safely save outside of
those locks. It's a function that's perfectly safe to put on the
message queue because it will automatically be disabled in certain
circumstances where it would be unsafe to call, such as on shutdown.
This code will also make it so that the project will not needlessly be
saved more than once if the SaveProjectDeferred call was pushed multiple
times on to the queue.
It currently says "Update check: latest version is x.x.x", which is a
bit confusion. It should say "Update check: last known remote version
is x.x.x" instead.
This makes it so that the log message for altering scene collections
and/or profiles is now below, and then the separator below that. This
makes it a bit more apparent that any loading/clearing/etc that happens
before the log message are associated with the log message.
Previously the sourceSceneRefs were being cleaned up in
OBSBasic::SceneItemRemoved; due to changes in
e82018579b the signal handler that called
OBSBasic::SceneItemRemoved is now being removed before the scene
triggers its item_remove signals
Adds setting profiles to the basic user interface. For each profile, a
subdirectory for the profile will be created in
[config_dir]/obs-studio/basic/profiles which will contain the settings
data for each profile.
Adds scene collections to the menu bar, which allows you to duplicate,
rename, remove, or add clean new scene collections.
Scene files are now stored in ./obs-studio/basic/scenes directory with
filesystem-safe names.
Originally this value defaulted to 1.5 downscaling, but on very high
resolution displays this would cause the default to be above 1280x720,
which is not ideal for streaming/recording due to the CPU usage
requirements.
Instead, it will now find the closest resolution with a pixel count
equivalent to or closest below 1280x720, and use that instead.
This prevents the weird stretching effect that occurs whenever a windows
is in the process of being resized by the user.
Originally it was intended as an optimization, but even on half-decent
computers it doesn't really have much benefit.
Apparently some raw lingering pointers to the item widgets may be
present inside of the QListView if you delete the item widgets directly,
and the only way to ensure those pointers are properly cleared is to
call ->clear() on the list widget instead of deleting each item
individually.
We were deleting each item individually because we thought that
->deleteLater might be also be called on other data within, but after
some testing, that turned out to not be the case, so it's safe to call
->clear() on the list widget.
As a note, deleting item widgets directly is dangerous due to the
potential for lingering raw internal pointers, and our case is unique
where we can get away with it; do not delete list item widgets directly
unless you intend on calling ->clear() or ->takeItem on the specific
item you do it to after.
Again, the reason why we are deleting list widget items manually is due
to the fact that Qt will always use ->deleteLater() on them if they are
not deleted manually, which puts their deletion on the queue. Only
problem is they cannot be removed from the queue once added, so
lingering references to sources will persist until the queue processes
them, which causes major problems if we need those objects deleted right
away.
When initializing with a default scene, save the data to ensure a file
is actually present when needed (such as for scene collections which may
need the file)
Add a central function for clearing all data: scenes, sources, widgets
such as lists that may contain source references in their sub-items,
dialogs which may contain source references. In certain circumstances
this data must be fully released and manually freed to ensure that there
are no outstanding references to obs data (such as on shutdown, where
all data should be properly freed).
These functions are designed to manually delete item widgets within
other widgets to prevent ->deleteLater from being called on them. This
prevents the item widgets from being stuck in the event queue, and
prevents references to things like sources from being stuck in the event
queue along with them if they're used in the item widget's class or
functions.
Right now, information about global audio sources is stored in both
scene files and in the config. These must be separated; there's no need
to store them in both when they can just be stored in the scenes file.
When using e.g. a color correction filter on any source and changing
any value (with slider enabled, e.g. contrast) to -0.10 the value would
get cycle between -0.07/-0.08 at some point when using the up arrow; it
would also get stuck on -0.69.
For the other direction, when starting from e.g. -0.02 the value would
jump from 0.05 to -0.08 when pressing the down arrow.
Problem was reported at https://obsproject.com/forum/threads/32450
The empty implementation for the QDataStream operators is necessary to fix
a Qt assertion: "QVariant::save: unable to save type
'std::vector<std::shared_ptr<OBSSignal> >' (type id: 1036)."
It doesn't seem like a full implementation of the stream operators would be
useful since the signal registration is very specific to the interaction
between the scenes and sources list, i.e. in case the scenes list ever accepts
scenes from sources (not 'obs_source's) other than itself (non InternalMove
drag&drop?) it would have to register those scenes with the libobs core which
should trigger the normal signal registration
