Renamed functions:
- obs_source_getframe (rename to obs_source_get_frame)
- obs_source_releaseframe (rename to obs_source_release_frame)
For the sake of consistency and helping to get rid of the "squishy
function name" issue
The naming here is a poor choice, a source type determines if a source
is either a regular input, a filter, or a transition. The ID is the
actual unique identifier of a source.
The plugin now uses the generic name "OBS" to identify itself
to pulseaudio.
Until now the pulseaudio plugin used a placeholder icon for the
mixer to display. Now that we have a real icon installed to the
system we can use that instead.
The NSApplication delegate was changed from a setDelegate/delegate
method pair to a property, while the definition of NSApp didn't change
(its type is id while the type should be NSApplication* or similar)
Fixesjp9000/obs-studio#221
The bug here is that when conversion is active, the source video frame
is initialized with the destination height/width/format instead of the
source height/width/format.
According to issue #204 on the obs-studio repository, always setting the
ABR rate control method fixes the issue. I checked, and this was and
issue, and that does seem to fix the issue properly.
With the recent change to module handling by BtbN, I felt that having
this information might be useful in case someone is actually using make
install to set up their libraries.
The OBSBasic UI will now allow the use of a subdirectory of the user
application data directory for third-party plugins. Though I'm not
entirely sure if this ideal or not. Regardless, this is one of the
first (of many) steps towards a plugin manager.
On windows, this is %appdata%/obs-studio/plugins
On linux, this is ~/.obs-studio/plugins
On mac, this is ~/Library/Application Support/obs-sudio/plugins
This functionality can now be handled automatically because locale can
now be freed seaparately from obs_module_unload with
obs_module_free_locale, which is called automatically when the module is
being freed.
Changed API:
- char *obs_find_plugin_file(const char *sub_path);
Changed to: char *obs_module_file(const char *file);
Cahnge it so you no longer need to specify a sub-path such as:
obs_find_plugin_file("module_name/file.ext")
Instead, now automatically handle the module data path so all you need
to do is:
obs_module_file("file.ext")
- int obs_load_module(const char *name);
Changed to: int obs_open_module(obs_module_t *module,
const char *path,
const char *data_path);
bool obs_init_module(obs_module_t module);
Change the module loading API so that if the front-end chooses, it can
load modules directly from a specified path, and associate a data
directory with it on the spot.
The module will not be initialized immediately; obs_init_module must
be called on the module pointer in order to fully initialize the
module. This is done so a module can be disabled by the front-end if
the it so chooses.
New API:
- void obs_add_module_path(const char *bin, const char *data);
These functions allow you to specify new module search paths to add,
and allow you to search through them, or optionally just load all
modules from them. If the string %module% is included, it will
replace it with the module's name when that string is used as a
lookup. Data paths are now directly added to the module's internal
storage structure, and when obs_find_module_file is used, it will look
up the pointer to the obs_module structure and get its data directory
that way.
Example:
obs_add_module_path("/opt/obs/my-modules/%module%/bin",
"/opt/obs/my-modules/%module%/data");
This would cause it to additionally look for the binary of a
hypthetical module named "foo" at /opt/obs/my-modules/foo/bin/foo.so
(or libfoo.so), and then look for the data in
/opt/obs/my-modules/foo/data.
This gives the front-end more flexibility for handling third-party
plugin modules, or handling all plugin modules in a custom way.
- void obs_find_modules(obs_find_module_callback_t callback, void
*param);
This searches the existing paths for modules and calls the callback
function when any are found. Useful for plugin management and custom
handling of the paths by the front-end if desired.
- void obs_load_all_modules(void);
Search through the paths and both loads and initializes all modules
automatically without custom handling.
- void obs_enum_modules(obs_enum_module_callback_t callback,
void *param);
Enumerates currently opened modules.
The version macro that modules use to compile versus the actual core
version that may be in use may be different, so this is a way to compare
them to check for compatibility issues later on.
Those functions are actually causing more problems than
helping out with the preview because the width/height is
updated immediately while the actual size of the frames
displayed changes later.
Due to the plugin creating a thread to retrieve and output the
captured image data, care must taken to not modify data the
thread reads from the outside while the thread is running.
In previous revisions some settings accessed by the capture
thread were written to in the update function which could cause
image corruption and in the worst case crashes.
The members of the data struct are now split into two groups,
those that are used by the thread while it is running and must
not be changed from the outside, and those can be changed at any
time.
This adds a function to prepare the source_frame struct for use
with obs_source_output_video. Since all of the values except for
the timestamp and data pointers are known in before it makes
little sense to compute them over and over again.
Due to the fact that v4l2 uses a single continuous memory segment
for multi planar formats we can also precompute memory offsets for
the planes.
