Live555获得的帧数据是否可以通过IPC bits links，能否用这种方式来显示？
live555 frame -> iPCBitsOutLinks ->ipcBitsInLinks -> decLinks ->displayLinks

流程： ipc out -> ipc video in -> dec -> dis 把live555的帧数往ipc out里面填充就可以了吗？就可以对live555在线直播了吗？我的代码是这样子： vooid* getFrame(handle,frame,userdata) [ Bitstream_Buf *pEmptyBuf = NULL; //Int32 status = TRUE; int chns[16] = [0];

bbywerwr 发表于 2018-5-31 07:58 是我写反了，因该是： IpcBitsOutLinkRTOS_CreateParams ipcBitsInVideoPrm; IpcBitsInLinkHLOS_CreateParams ipcBitsOutHostPrm; 改为这个： IpcBitsInLinkRTOS_CreateParams ipcBitsInVideoPrm; IpcBitsOutLinkHLOS_CreateParams ipcBitsOutHostPrm; 又一个问题： IpcBitsOutLink_getEmptyVideoBitStreamBufs(SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0, &emptyBufList, &reqInfo); if(0 == emptyBufList.numBufs) [ return 0; ] 这上面的语句无法申请获得buffer？求指教！ |

恩恩，我现在是这样子： SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0 => SYSTEM_VIDEO_LINK_ID_IPC_BITS_IN_0 => SYSTEM_LINK_ID_VDEC_0 => SYSTEM_VIDEO_LINK_ID_IPC_OUT_M3_0 => SYSTEM_VPSS_LINK_ID_IPC_IN_M3_0 => SYSTEM_LINK_ID_SW_MS_MULTI_INST_0 => SYSTEM_LINK_ID_DISPLAY_0 这样子连这些link应该是没问题的吧？第一个link是这样子操作的： ipcBitsOutHostId = SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0; System_LinkQueInfo queInfo; queInfo.numCh = 1; queInfo.chInfo[0].bufType = SYSTEM_BUF_TYPE_VIDBITSTREAM; queInfo.chInfo[0].codingformat = chainsCfg->chCfg[0].encFormat; queInfo.chInfo[0].height = chainsCfg->chCfg[0].outHeight; queInfo.chInfo[0].width = chainsCfg->chCfg[0].outWidth; queInfo.chInfo[0].memType = SYSTEM_MT_TILEDMEM; queInfo.chInfo[0].dataFormat = SYSTEM_DF_YUV420P; queInfo.chInfo[0].scanFormat = SYSTEM_SF_PROGRESSIVE; ipcBitsOutHostPrm.baseCreateParams.inQueParams.prevLinkId = SYSTEM_LINK_ID_INVALID; ipcBitsOutHostPrm.baseCreateParams.inQueParams.prevLinkQueId = 0; ipcBitsOutHostPrm.baseCreateParams.numOutQue = 1; ipcBitsOutHostPrm.baseCreateParams.numChPerOutQue[0] = 1; ipcBitsOutHostPrm.baseCreateParams.outQueParams[0].nextLink = ipcBitsInVideoId; ipcBitsOutHostPrm.baseCreateParams.notifyNextLink = FALSE; ipcBitsOutHostPrm.baseCreateParams.notifyPrevLink = FALSE; ipcBitsOutHostPrm.baseCreateParams.noNotifyMode = TRUE; Chains_ipcBitsInitCreateParams_BitsOutHLOS(&ipcBitsOutHostPrm,&queInfo); System_linkCreate(ipcBitsOutHostId,&ipcBitsOutHostPrm,sizeof(ipcBitsOutHostPrm)); System_linkStart(ipcBitsOutHostId); emptyBufList.numBufs =0 ; bitBufSize =1360*768/2; reqInfo.bufSize = bitBufSize; reqInfo.chNum = chns[0]; OSA_waitMsecs(8); frameStartTime = OSA_getCurTimeInMsec(); IpcBitsOutLink_getEmptyVideoBitStreamBufs(SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0, &emptyBufList, &reqInfo); if(0 == emptyBufList.numBufs) [ return 0; ] 可我这样获取第一个link的缓冲区的时候，失败了，返回来 emptyBufList.numBufs =0的，不知道哪里出错了？能帮我看看吗？ |

你这样做完全ok，我做过实验，从A8->ipcBitsOutlinks->ipcBitsInLinks->videoM3 decLink->videoM3 encLink->ipcBitsOutM3->ipcBitsInHost->A8这样是ok的；

送终鸡酒 发表于 2018-5-31 08:59 是的！我的成功出来了！ A8（live555 client） ->IPC OUT(Bit Out) ->IPC IN (Video IN) -> DecLink (Video)->(Video Out )(IPC ) -> (Vpass In)(IPC) SwMs -> Display 原来是我忘记配置Ipc BitoutLink NotifyNextLink 以及NotifyMode！配置就可以了！IPC都需要配置 NotifyNextLink 以及NotifyMode！ |

bbywerwr 发表于 2018-5-31 09:26 你好； 你可以检查一下System_linkDelete 的link的注销的顺序，看是哪个link导致的； |
