OBS Studio 30.2 RC

• 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

I tried this today, everything (monitors + spectrogram plugin) indicated that my mic + media source was producing audio, but on the stream it was silent. I checked a VOD and it had sound too, nothing changed other than me updating from latest stable to latest beta, and turning on enhanced broadcasting (auto for bitrate + video tracks).
Remaking sources makes audio work again, but I want to avoid this if possible.

Downgrading back to stable makes everything work again.
Is this a bug or me being dumb?

Thanks!

Hello! Can you shed some light on how the Twitch "Enhanced Broadcasting" encoder settings work? Once I toggle it on, all my encoder settings are disabled, and the bandwidth test stream bandwidth is at ~9000Kbps. What codec is being used? Can I change it? Is AV1 / NVENC supported on Twitch yet? Will it be with the Stable release of this version?

Twitch Inspector reports this:

as the encoder, which doesn't tell me anything useful.

Thank you!
