TEB `v50` Release

TEB beta v50 release

Release Date: 2025.03.25.

This TEB beta release is based on OBS Studio v31.0.2 and includes new features, changes, and bug fixes described at the link. Additionally, all upstream unreleased changes as of 2025.03.17 are also included.

⚠️ This release is more bleeding edge than builds from the recent past and includes many unreleased upstream OBS Studio changes.

ℹ️ For NVIDIA GPUs, v50 requires NVIDIA driver version 570.0 or higher (this applies to both Windows and Linux).

New Changes

  • Feature: Groundwork for supporting multiple canvas
  • Feature Removal: Remove Client Performance Events (Twitch-internal Berryessa)
  • Feature Removal: The option to enable Simulcast when using WHIP/WebRTC Output is removed from the TEB Beta build. Refer to Upstream PR#10885

Previously Released Changes

The following list describes changes in the TEB Beta build that were included in previous builds and are not available in the OBS Studio release. Where applicable, the upstream OBS Studio PR (pull request) is referenced.

  • Feature: Set the codec level properly when using AMF encoders Upstream PR#11548
  • Feature: Enable the Windows updater for Enhanced Broadcasting builds
  • Feature: Stream Delay Upstream PR#12003 and “Enable Network Optimizations” / “Enable TCP Pacing” Upstream PR#12004 are now compatible with Enhanced Broadcasting and have been re-enabled.
  • Feature: Dynamic Bitrate (beta) Support
  • Feature: Core Plugin File Checksum Validation
  • Feature Removal: Remove PresentMon telemetry
  • Bugfix: Fix a bug in the interaction between enabling Enhanced Broadcasting and Dynamic bitrate (beta)

TEB-Linux: Previously released changes

The following list describes Linux-specific changes in the TEB Beta build that are not available in the OBS Studio release. Where applicable, the upstream OBS Studio PR (pull request) is referenced.

  • Feature: Linux support has been enabled and supports NVIDIA, AMD, and Intel GPUs Upstream PR#11541
    • Feature: "Connect Account" option is now available (X11-based desktops)
    • Feature: Improve the GPU detection logic to prevent invalid information on multi-GPU systems
    • Improvement: Parse .flatpak-info file if present in flatpaks
    • Improvement: Handle "profile" setting string-to-integer conversion for VAAPI encoders in the TEB code instead of obs-ffmpeg
    • Bugfix: Fix GPU card probing logic to provide non-empty GPU data in the configuration request
  • Improvement: Enable JACK and PulseAudio for non-flatpak builds
  • Bug Fix (flatpak only): Fix AMD HEVC VAAPI vertical resolution (1920x1080)
    • Note: The fix only applies to flatpak. DEB and standalone builds will send the wrong vertical resolution for HEVC 1080p (1920x1088)
    • Applied an FFmpeg patch
    • KDE 6.8 runtime is now used upstream
