DVRRDK McFw: Can declink be connected to IPC frame out link?

Hi All,

In our project, we want to use DM8168 to decode an IPNC, then pass the frame to DSP to do abandoned object analysis. But when I connect the declink to an  ipc frame out link, see the following:

.ipcFramesOutVideoId = SYSTEM_VIDEO_LINK_ID_IPC_FRAMES_OUT_0;  

.ipcFramesInVpssId   = SYSTEM_VPSS_LINK_ID_IPC_FRAMES_IN_0;

 

it will produce errors.

    You can send decoder output buffer to DSP. A chain like below can achieve it:

     

    IpcBitsOutHost -> decLink -> ipcOutM3Video -> ipcInM3Vpss -> ipcFramesOutRTOS --> (nextLink) -> dupLink

                                                                                                                                            --> (processLink) -> ipcFramesInDSP
