GStreamer Interpipes

GStreamer Interpipes is a plugin that enables efficient communication between multiple GStreamer pipelines. It allows sharing buffers, reducing latency, and optimizing resource usage.

📌 Features

• Low-latency pipeline communication.
• Supports inter-source and inter-sink elements.
• Dynamically link/unlink pipelines without restarting.

🔗 Key Concepts

Interpipes introduce:

• interpipesink – Acts as a producer of media buffers.
• interpipesrc – Acts as a consumer, receiving data from interpipesink.

💡 Use Cases

• Multi-camera setups – Combine multiple camera feeds efficiently.
• Live video processing – Apply real-time filters across multiple streams.
• Edge AI & Computer Vision – Process data from multiple sources dynamically.

🚀 Example Pipeline

Start a producer pipeline:

gst-launch-1.0 -e interpipesrc name=src1 is-live=true ! interpipesink name=sink1

Connect a consumer pipeline to receive data:

gst-launch-1.0 -e interpipesrc listen-to=sink1 ! autovideosink
