The change log fixes several bugs in Beta 1, including a crash when canceling a stream attempt with incompatible settings, a WebSocket settings migration issue, a theme loading issue, Lua scripts not working on Linux, a chapter marker hotkey setting not showing up, incorrect Replay Buffer button text, theme overriding another theme with the same ID, a warning dialog box for Multitrack Video errors with untranslated buttons, clarification of warning messages,



OBS Studio 30.2.0 Beta 2

Note: NVIDIA users may need to update their GPU drivers to 531.61 (Windows) / 530.41.03 (Linux) or newer.

Note: The code signing certificate for OBS is being updated. This may impact game capture compatibility with some anti-cheat solutions starting with the next major OBS update. If you are a game or anti-cheat developer please see https://obsproject.com/kb/capture-hook-certificate-update for more information.

30.2 New Features
-----------------

* Added support for Multitrack Video streaming [palana]
+ On Twitch, this is known as Enhanced Broadcasting. Currently, this requires Windows and an NVIDIA GPU. Support for other platforms and GPU vendors is planned. For more information, see: https://help.twitch.tv/s/article/multiple-encodes
+ When this feature is enabled, the following data about your system will be sent to the streaming service when starting a stream:
* OBS config info (canvas width and height, frame rate, encoder width and height, VOD Audio Track setting, OBS version)
* CPU info (name, speed, core counts)
* GPU info (model, memory, driver version, device ID, vendor ID)
* Memory info (free, total)
* OS info (name, version, arch, emulation)
+ Windows info (gaming feature status: Game Bar, Game DVR, Game Mode, Hardware-accelerated GPU Scheduling)
* Multitrack Video settings (maximum streaming bandwidth, maximum video tracks)
* Added support for Enhanced RTMP/FLV multi-track audio and video [palana/kc5nra]
+ Replaces the old metadata-based "VOD Track"
* Added "Hybrid MP4" output format (BETA) [derrod]
+ Combines fault-tolerance of fragmented MP4 with wide compatibility and faster access times of regular MP4. For more information, see: https://obsproject.com/kb/hybrid-mp4
+ Supports inserting chapter markers into the file via a hotkey or API. These markers are supported by most video players and editing software, such as DaVinci Resolve
* Added Linux support to the native NVENC encoder [derrod]
+ NVENC AV1 is now supported on Linux
* Added Linux shared texture support to the NVENC encoder [derrod]
* Added Linux shared texture support to the QuickSync encoder [kkartaltepe]
* Added Linux shared texture support to the VA-API encoder [nowrep]
* Added HEVC support to WebRTC output [murillo128]
* Added Composable Themes system to simplify theme creation, maintenance, and enable future customisation options [derrod/Warchamp7]
+ Themes now consist of a base theme and variants that can be switched between in the new "Appearance" settings tab
+ Old themes will no longer work and will need to be updated to the new system. See the wiki page for details: https://github.com/obsproject/obs-studio/wiki/OBS-Studio-Theme-System

30.2 Changes
------------

* Various UI and Theme tweaks [Warchamp7]
