Release Notes: Live Video Captioning#

Version 1.0.0#

April 01, 2026

Live Video Captioning is a new sample application, using DLStreamer and VLMs to produce captions on live camera feed. It enables you to configure the VLM model used, prompt, frame selection, the rate at which the captions are generated, frame resolution, and more. It also presents usage metrics of CPU, iGPU, and memory. A rich UI displays all the configuration options, live camera feed, and the generated text.

In addition, the sample application may generate alerts with custom prompts, with customizable generation delay. Docker-based deployment is supported currently.
