Live555获得的帧数据是否可以通过IPC bits links

你好，

我认为这个chain没有问题。

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};

static UInt64 timestamp_base = 0;

Bitstream_BufList emptyBufList;
Bitstream_BufList fullBufList;
IpcBitsOutLinkHLOS_BitstreamBufReqInfo reqInfo;
UInt32 bitBufSize;

UInt32 frameStartTime = 0;
UInt32 frameEndTime = 0;
UInt32 frameInterTime = 8;
Int32 milliSecondsToSleep = 0;
//Chains_Ctrl *chCfg = (Chains_Ctrl *) user_data;

frameStartTime = OSA_getCurTimeInMsec();

bitBufSize =1360*768/2;

reqInfo.bufSize = bitBufSize;
reqInfo.chNum = chns[0];

IpcBitsOutLink_getEmptyVideoBitStreamBufs(SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0,
&emptyBufList,
&reqInfo);
if(0 == emptyBufList.numBufs)
{
return 0;
}
fullBufList.numBufs = 0;
pEmptyBuf = fullBufList.bufs[fullBufList.numBufs++] = emptyBufList.bufs[0];

memcpy(pEmptyBuf->addr, frame->frameBuf,frame->frameSize);
pEmptyBuf->fillLength = frame->frameSize;

UInt64 curTimeStamp =timestamp_base++ * 16;

pEmptyBuf->lowerTimeStamp = (UInt32)(curTimeStamp & 0xFFFFFFFF);
pEmptyBuf->upperTimeStamp = (UInt32)((curTimeStamp >> 32)& 0xFFFFFFFF);

if (fullBufList.numBufs)
{
IpcBitsOutLink_putFullVideoBitStreamBufs(SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0,
&fullBufList);
}

milliSecondsToSleep = 1;

frameEndTime = OSA_getCurTimeInMsec();
milliSecondsToSleep = frameInterTime + frameStartTime - frameEndTime;
if (milliSecondsToSleep > 0) {
OSA_waitMsecs(milliSecondsToSleep);
milliSecondsToSleep = 0;
}
return 0;
}

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？

live555 frame -> ipcBitsOutLinks ->ipcBitsInLinks -> decLinks ->ipcOut ->ipcIn ->displayLinks

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；

有一个问题我停止stop chain，按0然后结束当前demo

出现了这样子错误是什么原因呢？视频已经播放出来了的。

谢谢！

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；
