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.
The current path would prevent the browser source from loading if OBS
itself is in the "Application Support" folder, where it might end up
when being installed via certain distribution platforms.
This adjusts the existing hack to specifically check for the obs-studio
subfolder where the old browser source library would reside.
Currently if a module fails its load callback, it remains loaded and OBS
continues to call additional exports such as obs_module_post_load. This
goes against the documented behavior, which states that a module that
fails its load callback is unloaded.
This commit releases locale resources and frees the module's
information, preventing further callbacks from libobs. The module itself
(the DLL) is not yet unloaded from memory as os_dlclose is commented out
for causing unspecified issues - this should be revisited in the future.
When size of source_info_t is larger then current structure, memcpy
overruns. Size check is moved before the memcpy.
HANDLE_ERROR macro copies info to data but data is not used. When
calling free_type_data and type_data, the member of data should be used
to ensure the free_type_data is not out of bounds.
This function determines if something is an OBS plugin before attempting
to load it. On Windows, many plugins ship their dependent DLLs alongside
the plugin DLL, so OBS would load things like libcef.dll on startup only
to immediately free it. For other platforms, this is less of a concern
so this function is a no-op for now.
This improves startup time and reduces risk from dependent DLLs
potentially running code with unwanted side effects in DllMain.
Useful for sharing translated text from modules with the frontend. This
is technically already done via properties, but it would be nice to just
be able to explicitly look up locale text directly rather than have to
go through properties.
(This also modifies image-source, obs-text, text-freetype2, and UI)
This improves source definition versioning. To do this, it now stores
two identifier names. One "unversioned" which is the original name, and
one "versioned" with the version number appended.
This fixes both backward compatibility with older OBS versions, and
fixes the inability to use "add existing" in OBS itself on sources
created from older version definitions.
Adds the "audio_line" internal source type as a bare source type for the
sole purpose of outputting audio, and the obs_source_info::audio_mix
callback which allows mixing of those audio lines, which is then treated
as normal audio for the source. Audio line objects should be added as
sub-sources when multiple audio lines from a single source are needed,
then mixed together with the audio_mix callback.
The difference between the new obs_source_info::audio_mix callback and
obs_source_info::audio_render is that obs_source_info::audio_mix (along
with the audio_line source) are only one track, and it outputs audio to
the source automatically via obs_source_output_audio() when the call
completes. This allows the mixed audio to be treated like a normal
source's audio, in that you can filter it, change its volume, or monitor
it.
This change was necessary because the CEF (used with the browser source)
outputs multiple audio streams at once to a single browser source, so
it's the program's responsibility to mix those streams together itself.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
Allows the ability to encode by passing NV12 textures. This uses a
separate thread for texture-based encoders with a small queue of
textures. An output texture with a keyed mutex shared texture is locked
between OBS and each encoder. A new encoder callback and capability
flag is used to encode with textures.
On macOS, the older version of the browser plugin used to reside in a
different directory. This would cause two versions of obs-browser to
load if you installed the new version of OBS over the old version of
OBS. This fixes that bug with an slightly unsightly hack by
blacklisting that older module if it tries to load an obs-module that
resides in that specific older directory.
Correct "regsiter" to "register" in a couple function names. These
functions are currently unused. Let's correct these names before they
start getting used.
This allows the ability for certain types of modules (particularly
scripting-related modules) to initialize extra data when all other
modules have loaded. Because front-ends may wish to have custom
handling for loading modules, the front-end must manually call
obs_post_load_modules after it has completed loading all plug-in
modules.
Closesjp9000/obs-studio#965
(Note: This commit also modifies coreaudio-encoder, win-capture, and
win-mf modules)
This reduces logging to the user's log file. Most of the things
specified are not useful for examining log files, and make reading log
files more painful.
The things that are useful to log should be up to the front-end to
implement. The core and core plugins should have minimal mandatory
logging.
(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.
(Note: This commit breaks libobs compilation. Skip if bisecting)
Adds a "composite" source type which is used for sources that composite
one or more sub-sources. The audio_render callback is called for
composite sources to allow those types of sources to do custom
processing of the audio of its sub-sources.
This is useful for allowing the ability to have private data associated
with the object type definition structures. This private data can be
useful for things like plugin wrappers for other languages, or providing
dynamically generated object types.
When getting a blank module data file (indicating you want to get the
path to the module data directory itself), on certain operating systems
(windows) it will fail if you end the path with '/' or '\'. So simply
make sure that if a blank module sub-path is used, don't try to append a
slash.
The rationale for rejecting these register calls is that these functions
may be required for the plugin to work properly, which can't be
guaranteed when libobs doesn't know about them.
This behavior may be revisited once the plugin manager is implemented,
to e.g. make it configurable (potentially per plugin) to allow loading
newer plugins in case they are known to work with the older libobs
When globbing for modules, the intent was to ignore the . and ..
directories that might also be included in the glob search. It was
mistakenly doing a string compare on the 'path' variable which contains
the full path, rather than the 'file' variable which just contains the
found file itself, so the string compare always failed.
Typedef pointers are unsafe. If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data. I admit this was a fundamental mistake that must
be corrected.
All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.
This does not break ABI though, which is pretty nice.
