TEB `v42` Release

v42

Release Date: 2024.12.17

TEB v42 Base

TEB v42 New Changes

  • Improvement: TEB Linux (flatpak): Fix AMD HEVC VAAPI vertical resolution (1920x1080)
    • Applied an FFmpeg patch to the flatpak build, which requires libva API >= 1.21
    • Updated the KDE runtime to 6.8 from 6.6 (and updating libdatachannel to fix build errors) to get libva API >= 1.21
    • Note: The fix only applies to flatpak. DEB and standalone builds will send the wrong vertical resolution for HEVC 1080p (1920x1088)

Previous Changes Not Available in 31.0.0

  • Improvement: TEB Linux: Enable JACK and PulseAudio for non-flatpak builds
  • Improvement: TEB Linux: Parse .flatpak-info file if present in flatpaks
  • Improvement: TEB Linux: Handle "profile" setting string-to-integer conversion for VAAPI encoders in the TEB code instead of obs-ffmpeg
  • Feature: TEB Linux: "Connect Account" option is now available
  • Feature: TEB Linux: Improve the GPU detection logic to prevent invalid information on multi-GPU systems
  • Feature: Linux support has been enabled and supports NVIDIA and AMD GPUs
  • Feature: Add GPU optimized colorspace and range conversion
  • Feature Removal: Remove PresentMon telemetry
  • Feature: Set the codec level properly when using AMF encoders
  • Feature: Support pixel formats other than NV12 for the canvas, and convert to NV12 using the GPU for texture encoders
    • This allows the canvas to be recorded in I444 for example while live-streaming using NV12
    • Tested for NVIDIA and AMD GPUs
  • Feature: Enable the Windows updater for Enhanced Broadcasting builds
  • Feature Removal: Audio is no longer resampled to stereo, behavior is now the same as OBS Studio v31.0.0-rc1
  • Feature: Add an option to enable Simulcast when using WHIP/WebRTC Output
  • Feature: Stream Delay and “Enable Network Optimizations” / “Enable TCP Pacing” are now compatible with Enhanced Broadcasting and have been re-enabled
  • Feature: Client Performance Events (Twitch-internal Berryessa)
  • Feature: Dynamic Bitrate (beta) Support
  • Feature: Core Plugin File Checksum Validation
  • Bugfix: Fix a bug in the interaction between enabling Enhanced Broadcasting and Dynamic bitrate (beta)
  • Bugfix: Fix automatic reconnection behavior (i.e. when disconnected after 48 hours when running a 24/7 broadcast)
  • Bugfix: TEB Linux: Fix GPU card probing logic to provide non-empty GPU data in the configuration request

Previous Changes Now Available Upstream in OBS Studio

  • Feature: Amazon IVS Support for FindIngest
  • Feature: Broadcast Performance Metrics (Timestamps & Frame Counters)
  • Bugfix: Improve timestamp alignment for advanced codecs (AV1)
  • Bugfix: AutoConfig wizard was overwriting the stream key
  • Bugfix: If multitrack streaming failed, selecting the non-multitrack fallback option could cause a crash in some cases
