The call path is (v4l2_m2m_streamon -> device_run -> > ipu_image_convert_queue -> convert_start -> ipu_ic_task_init_rsc -> > init_csc). Looking at v7 of the mem2mem driver, it will set ycbcr_enc at the output side to V4L2_YCBCR_ENC_DEFAULT if colorspace is default. So colorspace will need to be set to something non-default in addition to setting ycbcr_enc, at the output side. I don't know whether gstreamer v4l2videoNconvertelement will do this, but you could hack the driver for now to get around it, and let Philipp know this may need a workaround in mem2mem for v8.
