Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased - ReleaseDate

Changed

  • Improve feature flag documentation and enable feature markers on items in docs.rs, that show under what conditions certain items are available.
  • Revamp the integration tests to use a mocking server instead of running against a real OBS instance. This was long overdue as the tests didn't work anymore and it became harder and harder to make all tests work due to bugs or behavior in OBS.

0.14.0 - 2025-01-01

Added

  • New features from obs-websocket v5.5.0
    • New RecordFileChanged event.
    • New split_file and create_chapter command for recordings.
  • Added builders for all request structures, available behind the new builder feature.
  • Allow disabling of the OBS Studio and OBS WebSocket version checks.

Changed

  • Updated tokio-tungstenite to the latest v0.26.1.
  • Updated all dependencies to their latest version.
  • BREAKING CHANGE: Reworked the ConnectConfig struct to provide a nice builder for it, available behind the new builder feature.
  • BREAKING CHANGE: Refactor several APIs to reduce the amount of external types exposed in the public API.

0.13.0 - 2024-09-23

Changed

  • Updated tokio-tungstenite to the latest v0.24.

Fixed

  • BREAKING CHANGE: Deserialize the UUIDs of scene list responses, effectively exchanging the name field for an id. This was an oversight when introducing the UUIDs.

0.12.0 - 2024-05-04

Added

  • New features from obs-websocket v5.3.0
    • New set_record_directory command, that allows to modify the output directory for recordings.
    • New NotReady status code, that signals the obs-websocket server is not ready yet to accept any commands.
  • New features from obs-websocket v5.4.0
    • BREAKING CHANGE: Support for UUIDs to identify sources, inputs, scenes and transitions. This includes various breaking changes around those fields to make it impossible to misuse them in requests (basically using an enum to only use the name or UUID in a request but not both).
    • New list_kinds command for filters.
    • New source command for scene items.
    • New InputSettingsChanged and SourceFilterSettingsChanged event.
  • BREAKING CHANGE: Extend the connection config with a connection_timeout setting that allows to cancel the connection attempt after a set duration. The Client::connect method now defaults to a 30 second timeout.

Removed

  • BREAKING CHANGE: Removed the Error::NoPassword variant, which was a relic from the previous v4.x API of obs-websocket. The new API doesn't provide any way to tell whether the password is the cause of an authentication error. However, the WebSocketCloseCode::AuthenticationFailed is the closest to identifying this error.

0.11.5 - 2023-09-04

Changed

  • Explicitly unsubscribe from all events when the events feature isn't enabled. By default, obs-websocket sends all possible events, but those are not needed without the events feature flag in obws.

Fixed

  • Any received event from obs-websocket was wrongly reported as error level log while the events feature flag wasn't enabled in obws. These are now handled properly and logged as trace level log.

0.11.4 - 2023-08-23

Changed

  • Unpin serde and update to 1.0.185, which resolved the issue in serde_derive serde-rs/serde#2538. Also, raised the version of time as it pinned the serde version as well.

0.11.3 - 2023-08-19

Changed

  • Updated several dependencies, most notably tokio-tungstenite to 0.20.
  • Pin serde to 1.0.171, as newer versions use a pre-compiled binary for the derive macros.

0.11.2 - 2023-06-22

Fixed

  • Some of the bitflag values like FontFlags, Alignment and EventSubscription were not always serialized as numbers but their string form, causing errors in the respective request or response.

0.11.1 - 2023-05-22

Added

  • All client methods now have a doc alias with the original name from the obs-websocket spec.
    • The search will point to the right function when putting the original name in the search bar on docs.rs (or in locally generated docs).
    • Latest rust-analyzer can use this information in the method completion menu.

0.11.0 - 2023-05-18

Added

  • New features from obs-websocket v5.1.0
    • New ScreenshotSaved event, that is triggered by hotkeys in the OBS UI.
    • New variants for the OutputState enum, that signal reconnecting and reconnected states.

Changed

  • BREAKING CHANGE: Due to the update of bitflags the list of derived traits changed.
  • Update all dependencies to their latest version, most notably base64, bitflags and tokio-tungstenite.
  • The MSRV is now 1.68.

0.10.0 - 2022-11-14

Changed

  • BREAKING CHANGE: Update to the new obs-websocket v5 API, which is a complete rewrite, so all APIs of this crate had to change as well. Expect all types and function calls to be slightly different.
    • In addition, I didn't agree with the new naming scheme in obs-websocket, as it includes a great amount of naming repetition. Therefore, most function calls and data structures/fields are named different to be more concise.
    • Thank you to @715209 and @Elinvynia for testing out these changes pre-release ❤️. Your ideas and bug reports helped a lot!
  • All response and event data structures now implement the recommended common traits, where possible. In addition, serde::Serialize and serde::Deserialize is implemented for all of them. That means, they can now be constructed easier, and used in more places, for example, as a HashMap key.

0.9.1 - 2022-02-25

Fixed

  • Deserialization of Freetype2 and GDI+ failed in some situations, especially when many fields were not set to a custom value (as OBS omits default values). Thank you @peddermaster2!

0.9.0 - 2021-12-20

This is going to be the last release before the upcoming obs-websocket v5.0 release. Support is currently in progress on the v5-api branch and the release is expected to be soon.

Added

  • Several new types are available at the requests::custom module, that can be used for the generic set_source_settings and set_transition_settings requests to provide typed versions for common sources and transitions out of the box.
    • Note: These typed versions are not covered by automated tests yet, so careful testing is advised.

Changed

  • BREAKING CHANGE: Updated many dependencies, including tokio-tungstenite which included some changes to the TLS feature.
  • BREAKING CHANGE: Replace the chrono crate with time to avoid potential security issues. This crate only uses the Duration type, but the dependency was still switched in case of future issues.
  • Reduce size of the crate bundle by excluding unnecessary files, making downloads from https://crates.io faster.
  • Improved on several spelling errors throughout the API docs.

0.8.0 - 2021-06-14

Added

  • Dependabot is now used to create new PRs for version updates in cargo and GitHub Actions.

Changed

  • BREAKING CHANGE: Upgraded to obs-websocket 4.9.1, adding a few new events and requests. Unfortunately although this looks like a patch release of obs-websocket, it actually included some breaking changes.
  • BREAKING CHANGE: As with the upgrade to 4.9.1, the new required minimum version for OBS is 27.0.0 and for obs-websocket is 4.9.1. Versions requirements have been further relaxed for OBS so that even a 28.0.0 release will work with the current version of obws.
  • Code coverage data is now directly hosted on GitHub Pages at https://dnaka91.github.io/obws, instead of using codecov.io. This has been done to reduce the amount of dependencies on external services and reduce security risks due to recent codecov incidents.
  • Several dependencies have been updated to their latest version.

Fixed

  • Internal renaming and fixes have been done, mostly for naming conventions or other clippy lints. No logical fixes related to obs-websocket though.

0.7.0 - 2021-03-27

Changed

  • The open_projector] request now accepts a struct for geometry to define the projector window instead of a simple string. This allows to set the geometry without the need to know about the Qt geometry works and how it has to be encoded.

Fixed

  • The version requirement for OBS Studio was reduced from 26.1.2 to 26.1.0 as the x.x.2 was a MacOS specific fix version and generally fix versions don't break API compatibility.

0.6.0 - 2021-03-16

Added

  • If the connection to obs-websocket is lost, a Event::ServerStopped event is sent to signal the disconnect. Thanks @715209 !

Changed

  • BREAKING CHANGE: Client::events now returns a Result and fails with an error when trying to get a new event stream while disconnected from obs-websocket.
  • BREAKING CHANGE: During Client::connect the version of OBS Studio and obs-websocket is now checked and the connection will fail if the versions are too old or too new.
  • The event streams returned from Client::events are properly being closed when the connection to obs-websocket is disconnected in any way.

Fixed

  • Requests were never finishing if the connection was lost in the meantime. They're now properly cancelled when a disconnect happens.
  • The TransitionVideoEnd event could not be deserialized as the from_scene field was wrongly a required field and was therefore changed to be optional. Thanks @715209 !

0.5.0 - 2021-03-07

Changed

  • BREAKING CHANGE: Upgraded to obs-websocket 4.9.0, adding all the new events and requests. Some existing ones have changes as well.
  • Dependencies updated to the latest version, including the just released tokio-tungstenite with support for rustls as TLS backend.
  • The tls feature now uses rustls instead of native-tls as backend.

Fixed

  • obs-websocket sends a non-JSON message when shutting down that is now properly handled instead of failing. Thanks @715209 !

0.4.0 - 2021-01-22

Added

  • The client can now be shut down with the disconnect function and will do so automatically on drop. It is still recommended to call this manually as it allows to wait for the client to fully close all the internal machinery.

Changed

  • Events are opt-in with the events feature flag to reduce final binary size when events aren't used.

Fixed

  • All fields of ConnectConfig have been made public to actually allow setting them.

0.3.0 - 2021-01-11

Added

  • Github actions added to run automated tests and lints on each commit.
  • Unit tests for all custom (de)serializers ensuring the right in-/output.
  • More integration tests, covering almost all requests now.
  • Added .editorconfig file to allow consistent indenting and other common editor settings.
  • Added a Justfile (similar to a Makefile) that allows to run common tasks and especially code coverage conveniently.
  • A new connect_with_config function that allows to customize the client behavior.
  • Support for TLS connections.

Changed

  • Update readme to show the current code coverage.
  • Upgraded to tokio 1.0 and all related dependencies.

Fixed

  • Corrected a few links in the API docs.
  • A required tokio feature was missing as the dev dependencies added it.

0.2.0

Added

  • Most request types implement Default for easier request creation.
  • Many integration tests.
  • Basic usage details in the docs and readme.

Changed

  • Parse into more concrete types where possible. For example durations and timestamps are represented as types from the chrono crate instead of strings and integers now.
  • Errors are specific now, using thiserror instead of anyhow allowing to match against the error and find out what exactly went wrong on a type level.

Fixed

  • Various small fixes in request and response types that were found while creating the integration tests.
  • Some links in the API docs were broken, pointing to private items.

0.1.0

Added

  • Initial release.
