GStreamer Buffer Synchronization Applications
The GStreamer Buffer Synchronization consists of a library and a GStreamer plug-in for synchronizing sensors:
Library
The Buffer Synchronization library is a sensor-agnostic framework to synchronize multiple sensor data. Within the sensor data, it is possible to synchronize accelerometer, gyroscope, camera, radar, and lidar data.
The library is written in C++17, allowing easy integration with the most common frameworks, such as GStreamer, NVIDIA Holoscan, and other custom applications compatible and linkable with C++.
Some of the features of the library:
- Same-rate sensor synchronization
- C++ integrable
- Lightweight
- No additional dependencies needed.
- Different-rate sensor synchronization (coming soon)
- Modes:
- Nearest neighbors (closest to time)
- Interpolation / data generation (coming soon)
GStreamer Element
The Buffer Synchronization library has been extended to support GStreamer as a plug-in to provide support for isochronous sensor synchronization (same data rate). It has the following features:
- Queue limit: limit how many buffers to store
- Modes: same as the library
- Multi-pad: similar to GStreamer's multiqueue
- Latency and proper clock handling
- Compatible with most memory types (NVMM and system memory)
Applications
The Buffer Synchronization Library can be used in the following applications, not limited to:
- Video stitching
- Birds-eye-view
- Multi-sensor applications like Electronic Video Stabilization.
- LiDar and Radar applications.
- Sensor fusion.
