Description

PCIeSink Node — sends samples to a PCIe-connected host (Modalix as PCIe target).

Wraps the simaaipciesink GStreamer element, which delivers buffers across the PCIe link to the host driver. Use as a terminal sink in pipelines where the Modalix board is acting as a PCIe target and the host is the actual consumer of the output.
