如何读一个H264文件，将数据转换到DM8127或DM8168的Bitstream_BufList

问题如下：
Receiving encoded stream from network via RTSPClient and decode those stream. I just know copy the encoded stream from the network intoBitstream_Buf->addr and I don't know how to initialize (fill up) all fields of Bitstream_Buf before put
them to the decoder by calling the function IpcBitsOutLink_putFullVideoBitStreamBufs.
Bitstream_BufList定义如下：
dm8127下有个例子：
Void *MultiCh_ipcBitsMain(Void *prm)
{
UInt32 i;
OSA_DmaCopy1D copy1D;
Bitstream_BufList fullBitsBufList;
Bitstream_BufList emptyBitsBufList;
IpcBitsOutLinkHLOS_BitstreamBufReqInfo ipcReqInfo;
OSA_printf("Entered IPC Bits Handler function\n");
gIpcBitsThObj.exitTh = FALSE;
gIpcBitsThObj.exitDone = FALSE;
while(gIpcBitsThObj.exitTh == FALSE)
{
OSA_semWait(&gIpcBitsNotifySem,OSA_TIMEOUT_FOREVER);
IpcBitsInLink_getFullVideoBitStreamBufs(gIpcBitsInHLOSId,&fullBitsBufList);
ipcReqInfo.numBufs = fullBitsBufList.numBufs;
for(i = 0;i < ipcReqInfo.numBufs;i++)
{
ipcReqInfo.minBufSize[i] = DEC_MIN_BUF_SIZE;
}
if(IpcBitsOutLink_getEmptyVideoBitStreamBufs(gIpcBitsOutHLOSId,&emptyBitsBufList,&ipcReqInfo) == IPC_BITSOUT_LINK_S_SUCCESS)
{
emptyBitsBufList.numBufs = fullBitsBufList.numBufs;
for(i = 0;i < fullBitsBufList.numBufs;i++)
{
if((Int32)emptyBitsBufList.bufs[i]->addr & 0x80000000)
{
goto skip;
}
emptyBitsBufList.bufs[i]->channelNum = fullBitsBufList.bufs[i]->channelNum;
emptyBitsBufList.bufs[i]->fillLength = fullBitsBufList.bufs[i]->fillLength;
emptyBitsBufList.bufs[i]->timeStamp = fullBitsBufList.bufs[i]->timeStamp;
if(gDmaHndl.chId == 0xFF)
{
memcpy(emptyBitsBufList.bufs[i]->addr,
(fullBitsBufList.bufs[i]->addr + fullBitsBufList.bufs[i]->startOffset),
fullBitsBufList.bufs[i]->fillLength);
}
else
{
copy1D.srcPhysAddr = (unsigned long)CMEM_getPhys(fullBitsBufList.bufs[i]->addr + fullBitsBufList.bufs[i]->startOffset);
copy1D.dstPhysAddr = (unsigned long)CMEM_getPhys(emptyBitsBufList.bufs[i]->addr);
copy1D.size = fullBitsBufList.bufs[i]->fillLength;
OSA_dmaCopy1D(&gDmaHndl,©1D,1);
}
}
IpcBitsOutLink_putFullVideoBitStreamBufs(gIpcBitsOutHLOSId,&emptyBitsBufList);
}
skip:
IpcBitsInLink_putEmptyVideoBitStreamBufs(gIpcBitsInHLOSId,&fullBitsBufList);
}
gIpcBitsThObj.exitDone = TRUE;
OSA_printf("Exiting IPC Bits Handler function\n");
return NULL;
}
参考这个例子：将h264数据送到videoM3解码时，出现错误；
1）在videoM3解码有问题，错误码为0x2000a00, 通过查找TI的文档，该错误码是一个32位，表示32个错误，此错误码表示第9,11,25位对应为1；
错误如下：
XDM_APPLIEDCONCEALMENT :Applied concealment;
XDM_CORRUPTEDDATA : Data problem/corruption;
IH264VDEC_ERR_MISSINGSLICE: one or more slices are completely missing in this picture;
因为使用的视频是用海康相机录的，使用海康工具将视频文件转换为标准h264文件，然后ultraEdit裁剪到0x00 00 00 01 67 前的数据，解决；
2）dm8148，我将h264数据送入videoM3 解码时，出错； if(IpcBitsOutLink_getEmptyVideoBitStreamBufs(IPCBITOUTHOSTTOVIDM3ID,&emptyBitsBufList,&ipcReqInfo) == IPC_BITSOUT_LINK_S_SUCCESS) dm8127 这个地方获取的地址emptyBitsBufList有时有问题，获取的是物理地址了，本来是虚拟地址的； 有人知道原因吗？
调试日志：
[host] ###Bit buff of size from the SR # 1 : 2073600
[host] IPC_BITSOUT:BitBuffer Alloc.PoolID:0,Size:0x1FA400
[host] IPCBITSOUTLINK:Translated Addr Virt:0x4189d080 To Phy:0x90000080
从这里看0x4189d080是虚拟地址，而 0x90000080是物理地址；
平时正常跑的时候，获取的地址是0x4189d080，而有时，获取的地址是0x90000080，然后拷贝了数据就出错了。
产生原因：
1)可能是由于读264文件时，IPCBitoutlink还未初始化；
解决办法：使用0x80000000过滤掉，另外当下面条件成立时，emptyBitsBufList的buff数可能为0，所以if语句中应该加一个条件过滤(emptyBitsBufList.numBufs>0)
if(IpcBitsOutLink_getEmptyVideoBitStreamBufs(IPCBITOUTHOSTTOVIDM3ID,&emptyBitsBufList,&ipcReqInfo) == IPC_BITSOUT_LINK_S_SUCCESS)
3）出现decLink_h264.c[333]::INTERNAL ERROR: -1 ALGPROCESS FAILED :STATUS
