DM8168 RDK中:ListMP_getHead(pObj->ListMPINHndl,)后来一直返回为空(NULL)问题请教

基于DM8168开发板硬件和RDK开发包,设计下面了Link流程: 【captureLink --> ipcFramesOutVpssLink -->ipcFramesInDspLink --> dspAlgLink -->ipcFramesOutDspLink --> ipcFramesInVpssLink -->tdisplayLink 】 目前图像可显示,但C6XDSP很快挂掉了. 检查发现ipcFramesOutDspLink的ipcFramesOutDspLink_releaseFrameBufs()函数中ListMP_getHead(pObj->ListMPINHndl,)后来一直返回为空(NULL)导致。RDK代码工程中没有搜索到ListMP_PutTail(pObj->ListMPINHndl,),只搜索到ListMP_PutTail(pObj->ListMPOUTHndl,),应该不是和前面ListMP_getHead(pObj->ListMPINHndl,)对应的。 请大侠们看看是啥原因? 另外,同样代码的ipcFramesOutVpssLink,为啥没这个问题?在captureLink 也没找到ListMP_PutTail(pObj->ListMPINHndl,)。
