.. _vvas_xskipframe: vvas_xskipframe ================== vvas_xskipframe plugin is used in video analytics pipelines in conjunction with :ref:`vvas_xreorderframe` plugin to control inference rate. It achieves this by using the user configured infer-interval property and determines which frames to be served for inference and which frames to be skipped for inference. For example, if the infer-interval is 1, all frames are sent for inference, if infer-interval is 2, then every alternate frame is sent for inference. This element has one sink pad and two source pads. It is multi-stream aware and its sink pad can connect with :ref:`vvas_xfunnel` element to accept frames from multiple streams. One source pad is connected to :ref:`vvas_xinfer` element to send the frames that are marked for inference, another source pad is connected to :ref:`vvas_xreorderframe` to send the frames marked skipped. vvas_xskipframe plugin adds frame id to the GstVvasSrcIDMeta metadata so that :ref:`vvas_xreorderframe` plugin can identify the order of the frames. Input and Output -------------------- vvas_xskipframe plugin is format agnostic and can accept any format on input and output pads.
