Release Notes: DL Streamer Pipeline Server#

Version 2026.1.0#

Release Date: June 17, 2026

New:

  • Added an exemplary pipeline configuration for NPU decode-and-inference (pallet_defect_detection pipeline using 1VA-API H.264 decode and gvadetect targeting the NPU device).

Improved:

  • Updated the base Docker image from intel/dlstreamer:2025.2.0-ubuntu22 to intel/dlstreamer:2026.0.0-ubuntu24. The default published image is now Ubuntu 24.

  • Updated the bundled OpenVINO™ Python package to 2026.0.0.

  • Replaced hardcoded render group IDs (109, 110, 992) in all Docker Compose files with a single configurable RENDER_GID environment variable, simplifying GPU/NPU device access across different host operating systems.

  • Improved Swagger/OpenAPI documentation formatting and readability for all REST API endpoints.

  • Graceful GStreamer pipeline shutdown: pipelines now terminate cleanly with improved shutdown logging.

Fixed:

  • Fixed a memory leak in the latency_times dictionary where per-pipeline entries accumulated indefinitely.

  • Replaced the x264enc H.264 encoder with openh264enc in the WebRTC streaming path, removing a GPL-licensed codec dependency.
