From 3f725b7eee496d7d0e0daea94df23a8daafbec40 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 2 Aug 2015 16:37:11 -0300 Subject: [PATCH] [media] v4l: vsp1: Decouple pipeline end of frame processing from vsp1_video To make the pipeline structure and operations usable without video devices the frame end processing must be decoupled from struct vsp1_video. Implement this by calling the video frame end function indirectly through a function pointer in struct vsp1_pipeline.
