Software-update: OBS Studio 28.0.0

OBS Studio logo (79 pix)Versie 28.0.0 van OBS Studio is uitgekomen. Open Broadcaster Software Studio is opensource en crossplatform software bedoeld voor het opnemen en streamen van videobeelden van een of meer bronnen, zoals een webcam, microfoon, mediabestanden en de desktop. In versie 28 is onder meer ondersteuning voor 10-bit en hdr-video encoding toegevoegd, is er een versie voor Apple hardware uitgerust met een Apple Silicon-cpu en is de overstap naar Qt 6 voor de gebruikersinterface gemaakt. De complete changelog voor deze uitgave is hieronder te vinden:

28.0: 10-bit and HDR Video Encoding Support

OBS now supports 10-bit and HDR, courtesy of rcdrone, YouTube, and Luxoft. New color format and color space settings have been added in the advanced settings to allow this.

Important notes about HDR and 10-bit:

  • HDR and 10-bit can only be encoded with AV1 and HEVC encoders.
    • 10-bit HEVC encoding requires NVIDIA 10-series, AMD 5000 series, or newer GPU. Intel QuickSync and Apple VT are not yet supported.
  • The recommended settings for HDR are Color Format P010 and Color Space Rec. 2100 PQ.
  • If you wish to encode 10-bit SDR, you can use Color Format P010 with an SDR color space (e.g. Rec. 709, Rec. 601). However, AV1 or HEVC will still be required.
  • HDR streaming is currently only supported via YouTube's HLS service via an HEVC encoder.
  • When composing in SDR, games that operate in HDR can now be properly tonemapped to SDR.
  • Video capture devices can be used to capture and stream in HDR if the device supports it (e.g. EVGA XR1 Pro, Elgato 4K60 Pro Mk.2, AverMedia Live Gamer 4K).
    • For a list of tested devices, see this page
  • Certain filters will not function if a source is rendering with HDR:
    • Apply LUT, Chroma Key, Color Key, Image Mask/Blend, Luma Key, Sharpness
  • Mac/Linux support is limited. HDR preview does not work, and several inputs/encoders still need to be updated.
28.0: Updating to Qt 6

As of May 2020, version 5 of the Qt user interface toolkit ceased public development and is no longer being updated. Since then, our need for a more up-to-date version has been increasing as time goes by. With version 28.0, we felt it was important for us to update our user interface toolkit to the latest version; not just to gain access to the latest features, but also for the latest bug fixes and improved support for newer operating systems and architectures such as Windows 11 and Apple Silicon. Unfortunately, this also means that certain plugins that depend on version 5 of Qt will no longer work when you upgrade to version 28.0 and will need to be updated.

During this beta period of OBS 28.0, many of those plugins which rely on Qt version 5 may not yet be updated yet, and we'll be working with third-party plugin developers in order to get them updated before the final release deploys.

Additionally, Qt 6 has dropped support for Windows 7 & 8, macOS 10.13 & 10.14, Ubuntu 18.04 and all 32-bit operating systems. As such, OBS will no longer be supported on these platforms.

For more details, please refer to our Discussion Post: Plan to Upgrade OBS Studio to Qt 6.

28.0: Native Apple Silicon Support

With OBS 28, OBS now has native builds for Apple Silicon systems. This means that OBS will run more optimally and without x86 emulation. Unfortunately, an important caveat for this is that many third-party plugins may not yet be readily available for Apple users running native Apple Silicon builds. Users can still use x86 builds of OBS if they desire a wider selection of third-party plugins that are not yet available natively for Apple Silicon.

28.0: New Features and Additions

  • Added application audio capture on Windows to allow capturing the audio output from a single process
  • Added the ability to select a separate video mix for the virtual camera
  • Added support for NVIDIA Background Removal on Windows (requires NVIDIA Video Effects SDK Runtime to be installed)

  • Added support for sending chat messages to YouTube from within OBS
  • Added file integrity check option on Windows to validate and repair the current OBS installation
  • Added improved macOS permissions flow on startup
  • The Video Capture Device source on Windows will now save/remember settings changed in the "Configure" dialog
  • Added “What’s New” dialog on macOS and Linux
28.0: Tweaks
  • Updated all dependencies to their latest versions
  • It is now possible to use any version of Python 3 on Windows and macOS rather than just 3.6

  • Added a rotation handle to sources selected in the preview
  • Added spacing distance helpers to sources selected in the preview
  • Added a keyboard shortcut to copy/paste scene item transformations

  • Moved Twitch/Restream OAuth to a serverless edge compute platform to improve reliability and response times, especially for users in Asia
  • Updated obs-browser's CEF (Chromium) to version 103 (5060) on all platforms, fixing a rendering crash on Windows

Waarom zijn plugins platform afhankelijk??? dat moet toch anders kunnen.
Kan jij toelichten welke platform onafhankelijke API men dan kan gebruiken?
Dat is aan de ontwikkelaars van de plugin. En ja, sommige plugins zijn alleen maar relevant op een bepaald platform.
Lijkt me nog best lastig.
De ontwikkeling van een cross platform video platform, waarbij elementen als video encoding vaak enorm platform afhankelijk zijn.
Ook dingen als HDR zijn absoluut niet gestandaardiseerd over Windows, Linux en Mac
Risico bestaat dat het 3 losse codebases worden, die handmatig functioneel hetzelfde moeten worden gehouden.
Geen eenvoudige opgave, lijkt me.
Dit is in wezen gewoon een transcoder applicatie, het is niet dermate afhankelijk van de implementatie van het OS. Worst case wordt de weergave niet in HDR getoond op de monitor van de gebruiker, maar dan nog gaan de HDR signalen gewoon mee in de stream. Maar programma's als VLC laten natuurlijk ook zien dat multi-OS niet multi-codebase oplevert.

Lijkt me dat OBS ook gewoon libavcodec gebruikt, dat gebruikt VLC ook. Zo hoeven ze zichzelf niet bezig te houden met platformspecifieke video/encoding/transcoding ondersteuning.
Ff snel de codebase bekijkend lijkt het erop dat ze zelfs alleen maar ffmpeg wrappen. En zelfs libvlc voor playback.
ffmpeg is een front-endje voor libavcodec. Libvlc ook, dus 2keer libavcodec :p

leuk ook die screenshot van obs 23, meerdere jaren oud.
Het ziet er anders alsnog bijna net zo uit...
28.0: Updating to Qt 6
  • Added new default Theme "Yami"
Als het goed is nu júist niet meer :p
Valt wel mee hoor, ziet er nog vrij hetzelfde uit. Het oogt wat platter en volgens mij iets andere kleuren maar geen extreme makeover.
