GstSEIMetadata – Insert & Extract Metadata in H.264/H.265 Video Streams
GstSEIMetadata plugin provides an elegant, efficient way to insert and extract metadata from H.264 and H.265 encoded video streams using Supplemental Enhancement Information (SEI). Designed for embedded applications that require synchronized video and data—such as AI tagging, sensor fusion, and analytics—this plugin allows developers to embed per-frame metadata directly into encoded streams without affecting playback or compatibility.
Whether you’re streaming, recording, or processing video, GstSEIMetadata gives you powerful control over how your data and media are synchronized, transported, and decoded.
Key Features:
-
Supports H.264 and H.265
Insert and extract SEI metadata in both AVC and HEVC streams. -
No Impact on Playback or Decoders
Receivers that don’t support SEI simply ignore the data—ensuring backward compatibility. -
Flexible Metadata Handling
Send object detection results, timestamps, camera data, or other custom payloads alongside video—without needing to multiplex. -
Transport-Independent
Works with any transport method (UDP, TCP, RTP, etc.)—no additional muxers required. -
Lightweight GStreamer Integration
Seamlessly integrates into your pipeline with minimal overhead and full support for streaming or file-based workflows.
Use Cases:
-
Real-time AI metadata tagging (e.g., bounding boxes or classification results)
-
Timestamp synchronization between multiple video streams
-
Combining sensor data (e.g., LiDAR, GPS, IMU) with video for autonomous systems
-
Medical imaging and diagnostic metadata embedding
-
Forensics, surveillance, and audit trail creation in recorded video
