Key Capabilities:
- Timestamp-Based Synchronization: Buffers are compared and aligned using their timestamps, allowing streams to remain temporally consistent before downstream processing.
- Multi-Stream Synchronization: Synchronize two or more camera or sensor streams within the same application.
- GStreamer Integration: The included GStreamer plugin provides an easy way to add synchronization to existing pipelines.
- Flexible Synchronization Modes: Configure how the reference timestamp is selected depending on the application requirements.
- Buffer Drop Management: Buffers outside the configured synchronization window can be dropped automatically to prevent outdated frames from propagating through the pipeline.
- Latency Control: Minimum and maximum latency settings provide additional control over how long buffers are held while waiting for synchronization.
- Event-Driven Operation: Synchronization, buffer drops, flushes, and failures can be reported through callbacks and GStreamer debug output.
- Cross-Platform Design: Built as a portable C++ library without dependence on dedicated hardware acceleration.
- Production-Ready Architecture: Designed for embedded, desktop, edge, industrial, and commercial multimedia systems.
Example Use Case:
An autonomous delivery robot uses multiple onboard cameras to navigate urban environments and avoid obstacles. Without hardware-triggered synchronization, frames from each camera arrive at slightly different times, causing inconsistencies in perception and object detection. This leads to poor spatial alignment and unreliable vision-based navigation.
RidgeRun’s GStreamer Buffer Synchronization library solves this by aligning video frames in software based on timestamps, ensuring that multi-camera streams are synchronized before processing. This enables consistent and accurate input to AI models and SLAM algorithms—no special hardware or GPIO needed. Ideal for embedded platforms where cost, space, or hardware limitations prevent hardware sync.

"As a side note: just to let you know, I'm really happy to be working with RidgeRun in general. It's pretty clear that you tell it like you see it, and know what you do and don't know; it's really refreshing. That's super rare on these kinds of technical engagements when everyone seems to either want to claim expertise they don't have, or are so cautious they are don't actually say anything useful"

"RidgeRun has been so good that part of me doesn't even want to write this testimonial—because if more companies discover them, I might have to share the amazing engineers I get to work with. But credit where credit's due: their team is sharp, responsive, and consistently delivers beyond expectations. They make tough technical challenges feel easy, and that's rare."
