The intention of this is to allow sources/outputs/etc to be created without being visible to the UI or save/load functions.

Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

(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.

The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

(Note: This commit breaks UI compilation. Skip if bisecting) API Removed: ------------------------ obs_add_source API Changed: ------------------------ obs_source_remove: Now just marks/signals a source for removal The concept of "user sources" is flawed: it was something that the front-end was forced to deal with if it wanted to automate source saving/loading, and often it had to code around it. That's not how saving/loading should work, a front-end should be allowed to manage lists of sources in the way it explicitly chooses, and it should be able to choose which sources it wants to save/load.

This function was removed even though the browser plugin was using this function on mac, so this is being put back in temporarily while the browser plugin is modified to remove this function.

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.

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

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

(Non-compiling commit: windowless-context branch) API Changed: --------------------- Removed functions: - obs_add_draw_callback - obs_remove_draw_callback - obs_resize - obs_preview_set_enabled - obs_preview_enabled Removed member variables from struct obs_video_info: - window_width - window_height - window Summary: --------------------- Changes the core libobs API to not be dependent upon a main window/view. If you wish to draw to a window/view, use an obs_display object to handle it. This allows the use of libobs without requiring a window to be present on the system. This is also prunes code that had to be needlessly duplicated to handle the "main" window.

If you don't need to see what's displayed, then this is particularly useful for two reasons: 1. It reduces the number of draw/present calls 2. It can prevent issues with certain hardware setups where rendering on a monitor hooked up to a separate card can experience slowdowns
