Media tech engineering company Konstrukt has introduced Omakase, an open-source media player.
The browser-native, timeline-first JavaScript framework is built specifically for frame-accurate playback, rich metadata visualisation, and complex quality control (QC) and media markup workflows, said the company.
Distributed under the Apache 2.0 license, Omakase Player aims to deliver an enterprise-grade solution with zero licensing fees and complete code ownership.
Key features include:
-
Unified Live and VoD: Player architecture that supports both real-time live feeds and file-based sources. It delivers frame-accurate playback, a sliding-window timeline, and thumbnail navigation out of the box.
-
Comprehensive Format Support: In-browser support for H.264/H.265 streams across HLS, Progressive MP4, and TAMS, alongside FairPlay, Widevine, and PlayReady DRM. Directly handles sidecar audio, text, and data tracks as additional media elements, including support for AAC, AC-3, MP3, WAV, IMSC, SRT, SCC, VTT, and JSON formats.
-
Extensible Multi-Lane Timeline and Markers: Renders media analysis, user markup, and AI/ML data across an interactive canvas. Connects temporal metadata to video playback for operational workflows such as semantic search, ad/promo insertion, frame annotation, review and approval, and QC.
-
QC Room-Ready: Unifies variable-speed playback, frame-stepping, jog/shuttle control, custom keyboard shortcuts, audio routing and soloing, VU metering, track visualisation, safe area overlays, technical metadata inspection, and dual-screen display management into a single framework for broadcast-accurate quality control entirely in the browser.
Omakase Player is already in production across cloud-native products, including SDVI’s Rally media supply chain platform.
“We selected Omakase Player for Rally because our customers needed more than basic playback: they needed frame-accurate review, multi-channel audio control, and support for the temporal metadata in a player that integrates our Rally Access panel in a browser,” said Chris Brähler, chief product officer at SDVI.
“Omakase gave us all of that in a player built specifically for professional media use cases. Its open-source foundation reflects the same commitment to open, interoperable workflows that we’ve built into Rally from the start. We’re excited to see that maturity and stability extend even further with Omakase 1.0, and we look forward to continuing to build on what’s already been a great partnership with Konstrukt.”
