    Yes you can use ipcFramesOutLinkHLOS to send the frames to vpss m3.

    You link connection should be of the form :

    SYSTEM_HOST_LINK_ID_IPC_FRAMES_OUT_0(A8)->SYSTEM_VIDEO_LINK_ID_IPC_FRAMES_IN_0(M3VPSS)

    Pls refer below file for example of connecting links to send frames to VPSS M3

    /dvr_rdk/mcfw/src_linux/mcfw_api/usecases/multichhd_vcap_venc_vdis.c

    Refer /dvr_rdk/demos/mcfw_api_demos/mcfw_demo/demo_vcap_venc_vdis_ipc_frames_exch.c for example application code to send frames to VPSS m3
