Sample Postprocess Library Configuration Reference - Sample Postprocess Library Configuration Reference - 6.3 English - XD056

The vvas_xinfer plugin loads a postprocess shared library at runtime to decode inference output tensors into structured results (classifications, detections). The library is specified by the library-path field inside the postprocess-config JSON object, and library-specific options are passed through the library-config JSON object.

Three reference postprocess libraries are shipped as source under vvas-gst-plugins/sys/infer/vvas_postprocess_models/ in the vvas repository. They are built as standalone shared libraries and installed to /usr/lib/ on the target.
