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

Core API functions changed: ----------------------------- EXPORT bool obs_reset_audio(struct audio_output_info *aoi); EXPORT bool obs_get_audio_info(struct audio_output_info *aoi); To: ----------------------------- EXPORT bool obs_reset_audio(const struct obs_audio_info *oai); EXPORT bool obs_get_audio_info(struct obs_audio_info *oai); Core structure added: ----------------------------- struct obs_audio_info { uint32_t samples_per_sec; enum speaker_layout speakers; uint64_t buffer_ms; }; Non-interleaved (planar) floating point output is standard with audio filtering, so to prevent audio filters from having to worry about different audio format implementations and for the sake consistency between user interfaces, make it so that audio is always set to non-interleaved floating point output.

The main view does not need to worry about hiding/deactivation of sources when it's being freed here, when the obs context is shutting down in this section of obs, all the sources are being freed, thus there's no need to worry about deactivating/hiding sources.

API changed: -------------------------- void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder); obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output); obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings); Changed to: -------------------------- /* 'idx' specifies the track index of the output */ void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder, size_t idx); /* 'idx' specifies the track index of the output */ obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output, size_t idx); /* 'mixer_idx' specifies the mixer index to capture audio from */ obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings, size_t mixer_idx); Overview -------------------------- This feature allows multiple audio mixers to be used at a time. This capability was able to be added with surprisingly very little extra overhead. Audio will not be mixed unless it's assigned to a specific mixer, and mixers will not mix unless they have an active mix connection. Mostly this will be useful for being able to separate out specific audio for recording versus streaming, but will also be useful for certain streaming services that support multiple audio streams via RTMP. I didn't want to use a variable amount of mixers due to the desire to reduce heap allocations, so currently I set the limit to 4 simultaneous mixers; this number can be increased later if needed, but honestly I feel like it's just the right number to use. Sources: Sources can now specify which audio mixers their audio is mixed to; this can be a single mixer or multiple mixers at a time. The obs_source_set_audio_mixers function sets the audio mixer which an audio source applies to. For example, 0xF would mean that the source applies to all four mixers. Audio Encoders: Audio encoders now must specify which specific audio mixer they use when they encode audio data. Outputs: Outputs that use encoders can now support multiple audio tracks at once if they have the OBS_OUTPUT_MULTI_TRACK capability flag set. This is mostly only useful for certain types of RTMP transmissions, though may be useful for file formats that support multiple audio tracks as well later on.

Previously, the design for the interaction between the encoder thread and the graphics thread was that the encoder thread would signal to the graphics thread when to start drawing each frame. The original idea behind this was to prevent mutually cascading stalls of encoding or graphics rendering (i.e., if rendering took too long, then encoding would have to catch up, then rendering would have to catch up again, and so on, cascading upon each other). The ultimate goal was to prevent encoding from impacting graphics and vise versa. However, eventually it was realized that there were some fundamental flaws with this design. 1. Stray frame duplication. You could not guarantee that a frame would render on time, so sometimes frames would unintentionally be lost if there was any sort of minor hiccup or if the thread took too long to be scheduled I'm guessing. 2. Frame timing in the rendering thread was less accurate. The only place where frame timing was accurate was in the encoder thread, and the graphics thread was at the whim of thread scheduling. On higher end computers it was typically fine, but it was just generally not guaranteed that a frame would be rendered when it was supposed to be rendered. So the solution (originally proposed by r1ch and paibox) is to instead keep the encoding and graphics threads separate as usual, but instead of the encoder thread controlling the graphics thread, the graphics thread now controls the encoder thread. The encoder thread keeps a limited cache of frames, then the graphics thread copies frames in to the cache and increments a semaphore to schedule the encoder thread to encode that data. In the cache, each frame has an encode counter. If the frame cache is full (e.g., the encoder taking too long to return frames), it will not cache a new frame, but instead will just increment the counter on the last frame in the cache to schedule that frame to encode again, ensuring that frames are on time and reducing CPU usage by lowering video complexity. If the graphics thread takes too long to render a frame, then it will add that frame with the count value set to the total amount of frames that were missed (actual legitimately duplicated frames). Because the cache gives many frames of breathing room for the encoder to encode frames, this design helps improve results especially when using encoding presets that have higher complexity and CPU usage, minimizing the risk of needlessly skipped or duplicated frames. I also managed to sneak in what should be a bit of an optimization to reduce copying of frame data, though how much of an optimization it ultimately ends up being is debatable. So to sum it up, this commit increases accuracy of frame timing, completely removes stray frame duplication, gives better results for higher complexity encoding presets, and potentially optimizes the frame pipeline a tiny bit.

The boolean variables which stored whether frames have been rendered/downloaded/converted/etc were not being reset when video restarted, causing frames to not be sent in the correct order whenever video was reset. This could lead to minor desync of video/audio.

This adds bicubic and lanczos scaling capability to libobs to improve scaling quality and sharpness when the output resolution has to be scaled relative to the base resolution. Bilinear is also available, although bilinear has rather poor quality and causes scaling to appear blurry. If the output resolution is close to the base resolution, then bilinear is used instead as an optimization, as there's no need to use these shaders if scaling is not in use. The Bicubic and Lanczos effects are also exposed via exported function to allow the ability to use those shaders in plugin modules if desired. The API change adds a variable 'scale_type' to the obs_video_info structure that allows the user interface to choose what type of scaling filter should be used.

This was an important change because we were originally using an hard-coded 709/partial range color matrix for the output, which was causing problems for people wanting to use different formats or color spaces. This will now automatically generate the color matrix depending on the format, color space, and range, or use an identity matrix if the video format is RGB instead of YUV.

At the start of each render loop, it would get the timestamp, and then it would then assign that timestamp to whatever frame was downloaded. However, the frame that was downloaded was usually occurred a number of frames ago, so it would assign the wrong timestamp value to that frame. This fixes that issue by storing the timestamps in a circular buffer.

The graphics subsystem was not being freed here, for example if a required effect failed to compile it would still successfully have the graphics subsystem sans required effect. The graphics subsystem should be completely shut down if required libobs effects fail to compile.

This Fixes a minor flaw with the API where data had to always be mutable to be usable by the API. Functions that do not modify the fundamental underlying data of a structure should be marked as constant, both for safety and to signify that the parameter is input only and will not be modified by the function using it.

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.

This makes it easier to do two things: 1.) Get the skipped frames count relative to each specific output 2.) Make it so that getting the 'current' log will always contain information about skipped frames. Before, you'd have to force the user to restart the program and get the last log, which was really annoying when you just wanted to see how the encoders were performing.

API Removed: - graphics_t obs_graphics(); Replaced With: - void obs_enter_graphics(); - void obs_leave_graphics(); Description: obs_graphics() was somewhat of a pointless function. The only time that it was ever necessary was to pass it as a parameter to gs_entercontext() followed by a subsequent gs_leavecontext() call after that. So, I felt that it made a bit more sense just to implement obs_enter_graphics() and obs_leave_graphics() functions to do the exact same thing without having to repeat that code. There's really no need to ever "hold" the graphics pointer, though I suppose that could change in the future so having a similar function come back isn't out of the question. Still, this at least reduces the amount of unnecessary repeated code for the time being.

Changed: - obs_source_gettype To: - enum obs_source_type obs_source_get_type(obs_source_t source); - const char *obs_source_get_id(obs_source_t source); This function was inconsistent for a number of reasons. First, it returns both the ID and the type of source (input/transition/filter), which is inconsistent with the name of "get type". Secondly, the 'squishy' naming convention which has just turned out to be bad practice and causes inconsistencies. So it's now replaced with two functions that just return the type and the ID.
