Description

PCIeSrc Node — receives samples from a PCIe-connected host (Modalix as PCIe target).

Wraps the legacy simaaipciesrc GStreamer element which uses standard GStreamer buffer allocation (no SiMa DMA allocator), keeping memory usage low and compatible with all board configurations. Use as the source in pipelines where the host pushes frames into the Modalix board over PCIe.
