- Updated the services API so that it links up with an output and the output gets data from that service rather than via settings. This allows the service context to have control over how an output is used, and makes it so that the URL/key/etc isn't necessarily some static setting. Also, if the service is attached to an output, it will stick around until the output is destroyed. - The settings interface has been updated so that it can allow the usage of service plugins. What this means is that now you can create a service plugin that can control aspects of the stream, and it allows each service to create their own user interface if they create a service plugin module. - Testing out saving of current service information. Saves/loads from JSON in to obs_data_t, seems to be working quite nicely, and the service object information is saved/preserved on exit, and loaded again on startup. - I agonized over the settings user interface for days, and eventually I just decided that the only way that users weren't going to be fumbling over options was to split up the settings in to simple/basic output, pre-configured, and then advanced for advanced use (such as multiple outputs or services, which I'll implement later). This was particularly painful to really design right, I wanted more features and wanted to include everything in one interface but ultimately just realized from experience that users are just not technically knowledgable about it and will end up fumbling with the settings rather than getting things done. Basically, what this means is that casual users only have to enter in about 3 things to configure their stream: Stream key, audio bitrate, and video bitrate. I am really happy with this interface for those types of users, but it definitely won't be sufficient for advanced usage or for custom outputs, so that stuff will have to be separated. - Improved the JSON usage for the 'common streaming services' context, I realized that JSON arrays are there to ensure sorting, while forgetting that general items are optimized for hashing. So basically I'm just using arrays now to sort items in it.

Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

- Fix an issue that could occur when using more than one video encoder. Audio/video would not sync up correctly because they were expected to be paired with a particular encoder. This simply adds a little helper variable to encoder packets that specifies the system time in microseconds. We then use that system time to sync - Fix an issue with x264 with fractional FPS rates (29.97 and 59.94 particularly) where it would create ridiculously large stream outputs. The problem was that you shouldn't set the timebase_* variables in the x264 params manually, let x264 handle the default values for it and leave them at 0. - Make x264 use CFR output, because there's no reason to ever use VFR in this case.

- Implement the RTMP output module. This time around, we just use a simple FLV muxer, then just write to the stream with RTMP_Write. Easy and effective. - Fix the FLV muxer, the muxer now outputs proper FLV packets. - Output API: * When using encoders, automatically interleave encoded packets before sending it to the output. * Pair encoders and have them automatically wait for the other to start to ensure sync. * Change 'obs_output_signal_start_fail' to 'obs_output_signal_stop' because it was a bit confusing, and doing this makes a lot more sense for outputs that need to stop suddenly (disconnections/etc). - Encoder API: * Remove some unnecessary encoder functions from the actual API and make them internal. Most of the encoder functions are handled automatically by outputs anyway, so there's no real need to expose them and end up inadvertently confusing plugin writers. * Have audio encoders wait for the video encoder to get a frame, then start at the exact data point that the first video frame starts to ensure the most accrate sync of video/audio possible. * Add a required 'frame_size' callback for audio encoders that returns the expected number of frames desired to encode with. This way, the libobs encoder API can handle the circular buffering internally automatically for the encoder modules, so encoder writers don't have to do it themselves. - Fix a few bugs in the serializer interface. It was passing the wrong variable for the data in a few cases. - If a source has video, make obs_source_update defer the actual update callback until the tick function is called to prevent threading issues.

Improve the properties API so that it can actually respond somewhat to user input. Maybe later this might be further improved or replaced with something script-based. When creating a property, you can now add a callback to that property that notifies when the property has been changed in the user interface. Return true if you want the properties to be refreshed, or false if not. Though now that I think about it I doubt there would ever be a case where you would have this callback and *not* refresh the properties. Regardless, this allows functions to change the values of properties or settings, or enable/disable/hide other property controls from view dynamically.

- obs-outputs module: Add preliminary code to send out data, and add an FLV muxer. This time we don't really need to build the packets ourselves, we can just use the FLV muxer and send it directly to RTMP_Write and it should automatically parse the entire stream for us without us having to do much manual code at all. We'll see how it goes. - libobs: Add AVC NAL packet parsing code - libobs/media-io: Add quick helper functions for audio/video to get the width/height/fps/samplerate/etc rather than having to query the info structures each time. - libobs (obs-output.c): Change 'connect' signal to 'start' and 'stop' signals. 'start' now specifies an error code rather than whether it simply failed, that way the client can actually know *why* a failure occurred. Added those error codes to obs-defs.h. - libobs: Add a few functions to duplicate/free encoder packets

- Make it so that encoders can be assigned to outputs. If an encoder is destroyed, it will automatically remove itself from that output. I specifically didn't want to do reference counting because it leaves too much potential for unchecked references and it just felt like it would be more trouble than it's worth. - Add a 'flags' value to the output definition structure. This lets the output specify if it uses video/audio, and whether the output is meant to be used with OBS encoders or not. - Remove boilerplate code for outputs. This makes it easier to program outputs. The boilerplate code involved before was mostly just involving connecting to the audio/video data streams directly in each output plugin. Instead of doing that, simply add plugin callback functions for receiving video/audio (either encoded or non-encoded, whichever it's set to use), and then call obs_output_begin_data_capture and obs_output_end_data_capture to automatically handle setting up connections to raw or encoded video/audio streams for the plugin. - Remove 'active' function from output callbacks, as it's no longer really needed now that the libobs output context automatically knows when the output is active or not. - Make it so that an encoder cannot be destroyed until all data connections to the encoder have been removed. - Change the 'start' and 'stop' functions in the encoder interface to just an 'initialize' callback, which initializes the encoder. - Make it so that the encoder must be initialized first before the data stream can be started. The reason why initialization was separated from starting the encoder stream was because we need to be able to check that the settings used with the encoder *can* be used first. This problem was especially annoying if you had both video/audio encoding. Before, you'd have to check the return value from obs_encoder_start, and if that second encoder fails, then you basically had to stop the first encoder again, making for unnecessary boilerplate code whenever starting up two encoders.

- Add a properties window for sources so that you can now actually edit the settings for sources. Also, display the source by itself in the window (Note: not working on mac, and possibly not working on linux). When changing the settings for a source, it will call obs_source_update on that source when you have modified any values automatically. - Add a properties 'widget', eventually I want to turn this in to a regular nice properties view like you'd see in the designer, but right now it just uses a form layout in a QScrollArea with regular controls to display the properties. It's clunky but works for the time being. - Make it so that swap chains and the main graphics subsystem will automatically use at least one backbuffer if none was specified - Fix bug where displays weren't added to the main display array - Make it so that you can get the properties of a source via the actual pointer of a source/encoder/output in addition to being able to look up properties via identifier. - When registering source types, check for required functions (wasn't doing it before). getheight/getwidth should not be optional if it's a video source as well. - Add an RAII OBSObj wrapper to obs.hpp for non-reference-counted libobs pointers - Add an RAII OBSSignal wrapper to obs.hpp for libobs signals to automatically disconnect them on destruction - Move the "scale and center" calculation in window-basic-main.cpp to its own function and in its own source file - Add an 'update' callback to WASAPI audio sources

- Implement OBS encoder interface. It was previously incomplete, but now is reaching some level of completion, though probably should still be considered preliminary. I had originally implemented it so that encoders only have a 'reset' function to reset their parameters, but I felt that having both a 'start' and 'stop' function would be useful. Encoders are now assigned to a specific video/audio media output each rather than implicitely assigned to the main obs video/audio contexts. This allows separate encoder contexts that aren't necessarily assigned to the main video/audio context (which is useful for things such as recording specific sources). Will probably have to do this for regular obs outputs as well. When creating an encoder, you must now explicitely state whether that encoder is an audio or video encoder. Audio and video can optionally be automatically converted depending on what the encoder specifies. When something 'attaches' to an encoder, the first attachment starts the encoder, and the encoder automatically attaches to the media output context associated with it. Subsequent attachments won't have the same effect, they will just start receiving the same encoder data when the next keyframe plays (along with SEI if any). When detaching from the encoder, the last detachment will fully stop the encoder and detach the encoder from the media output context associated with the encoder. SEI must actually be exported separately; because new encoder attachments may not always be at the beginning of the stream, the first keyframe they get must have that SEI data in it. If the encoder has SEI data, it needs only add one small function to simply query that SEI data, and then that data will be handled automatically by libobs for all subsequent encoder attachments. - Implement x264 encoder plugin, move x264 files to separate plugin to separate necessary dependencies. - Change video/audio frame output structures to not use const qualifiers to prevent issues with non-const function usage elsewhere. This was an issue when writing the x264 encoder, as the x264 encoder expects non-const frame data. Change stagesurf_map to return a non-const data type to prevent this as well. - Change full range parameter of video scaler to be an enum rather than boolean

- Add some temporary streaming code using FFmpeg. FFmpeg itself is not very ideal for streaming; lack of direct control of the sockets and no framedrop handling means that FFmpeg is definitely not something you want to use without wrapper code. I'd prefer writing my own network framework in this particular case just because you give away so much control of the network interface. Wasted an entire day trying to go through FFmpeg issues. There's just no way FFmpeg should be used for real streaming (at least without being patched or submitting some sort of patch, but I'm sort of feeling "meh" on that idea) I had to end up writing multiple threads just to handle both connecting and writing, because av_interleaved_write_frame blocks every call, stalling the main encoder thread, and thus also stalling draw signals. - Add some temporary user interface for streaming settings. This is just temporary for the time being. It's in the outputs section of the basic-mode settings - Make it so that dynamic arrays do not free all their data when the size just happens to be reduced to 0. This prevents constant reallocation when an array keeps going from 1 item to 0 items. Also, it was bad to become dependent upon that functionality. You must now always explicitly call "free" on it to ensure the data is free, and that's how it should be. Implicit functionality can lead to confusion and maintainability issues.

Make it so obs_data settings input in to *_update are applied to the existing settings rather than fully replace the existing settings. That way you can update with only certain specific settings, leaving other settings untouched. Of course if you're already using the original settings pointer in the first place then you've already done that, so it'll just ignore it because you've already applied them.

The API used to be designed in such a way to where it would expect exports for each individual source/output/encoder/etc. You would export functions for each and it would automatically load those functions based on a specific naming scheme from the module. The idea behind this was that I wanted to limit the usage of structures in the API so only functions could be used. It was an interesting idea in theory, but this idea turned out to be flawed in a number of ways: 1.) Requiring exports to create sources/outputs/encoders/etc meant that you could not create them by any other means, which meant that things like faruton's .net plugin would become difficult. 2.) Export function declarations could not be checked, therefore if you created a function with the wrong parameters and parameter types, the compiler wouldn't know how to check for that. 3.) Required overly complex load functions in libobs just to handle it. It makes much more sense to just have a load function that you call manually. Complexity is the bane of all good programs. 4.) It required that you have functions of specific names, which looked and felt somewhat unsightly. So, to fix these issues, I replaced it with a more commonly used API scheme, seen commonly in places like kernels and typical C libraries with abstraction. You simply create a structure that contains the callback definitions, and you pass it to a function to register that definition (such as obs_register_source), which you call in the obs_module_load of the module. It will also automatically check the structure size and ensure that it only loads the required values if the structure happened to add new values in an API change. The "main" source file for each module must include obs-module.h, and must use OBS_DECLARE_MODULE() within that source file. Also, started writing some doxygen documentation in to the main library headers. Will add more detailed documentation as I go.

- Add planar audio support. FFmpeg and libav use planar audio for many encoders, so it was somewhat necessary to add support in libobs itself. - Improve/adjust FFmpeg test output plugin. The exports were somewhat messed up (making me rethink how exports should be done). Not yet functional; it handles video properly, but it still does not handle audio properly. - Improve planar video code. The planar video code was not properly accounting for row sizes for each plane. Specifying row sizes for each plane has now been added. This will also make it more compatible with FFmpeg/libav. - Fixed a bug where callbacks wouldn't create properly in audio-io and video-io code. - Implement 'blogva' function to allow for va_list usage with libobs logging.

- Add 'set_default' functions to obs-data.*. These functions ensure that a paramter exists and that the parameter is of a specific type. If not, it will create or overwrite the value with the default setting instead. These functions are meant to be explicitly called before using any of the 'get' functions. The reason why it was designed this way is to encourage defaults to be set in a single place/function. For example, ideal usage is to create one function for your data, "set_my_defaults(obs_data_t data)", set all the default values within that function, and then call that function on create/update, that way all defaults are centralized to a single place. - Ensure that data passed to sources/encoders/outputs/etc is always valid, and not a null value. - While I'm remembering, fix a few defaults of the main program config file data.

- First, I redid the output interface for libobs. I feel like it's going in a pretty good direction in terms of design. Right now, the design is so that outputs and encoders are separate. One or more outputs can connect to a specific encoder to receive its data, or the output can connect directly to raw data from libobs output itself, if the output doesn't want to use a designated encoder. Data is received via callbacks set when you connect to the encoder or raw output. Multiple outputs can receive the data from a single encoder context if need be (such as for streaming to multiple channels at once, and/or recording with the same data). When an encoder is first connected to, it will connect to raw output, and start encoding. Additional connections will receive that same data being encoded as well after that. When the last encoder has disconnected, it will stop encoding. If for some reason the encoder needs to stop, it will use the callback with NULL to signal that encoding has stopped. Some of these things may be subject to change in the future, though it feels pretty good with this design so far. Will have to see how well it works out in practice versus theory. - Second, Started adding preliminary RTMP/x264 output plugin code. To speed things up, I might just make a direct raw->FFmpeg output to create a quick output plugin that we can start using for testing all the subsystems.
