达芬奇A8传递数据给M3时BUFSTATE改变？

如题，A8在传递h264视频文件时，发送的状态为2（即IPC_BITBUF_STATE_OUTQUE），但VIDEOM3接收到时判断得到的状态为3（即IPC_BITBUF_STATE_INQUE），导致ASSERTION报错，为什么BUFSTATE会改变？

下面是具体提示：

[host] ###chenh<encdec>>> IpcBitsOutLink_putFullBufs sending notify to 268435486,NOW STATE is :0x00000002
 [m3video] NOW GET BUF STATE IS : 3
 [m3video]  15715: Assertion @ Line: 292 in links_common/ipcBitsIn/ipcBitsInLink_tsk.c: SYSTEM_IPC_BITS_GET_BUFSTATE(pListElem->bufState) == IPC_BITBUF_STATE_OUTQUE : failed !!!

另外，发送h264文件时，IpcBitsOutLink_getEmptyVideoBitStreamBufs(gIpcBitsOutHLOSId,&emptyBitsBufList,&ipcReqInfo)中的ipcReqInfo参数如何确定？emptyBitsBufList要怎么修改参数才能把h264文件发送给VIDEOM3？下面是我现在的h264发送线程（h264的分辨率时1280×738）：

Chris Meng：

Tony，

你有修改过memory map/bld/cache相关的部分？

会不会和cache相关？

tony gan：

回复 Chris Meng:

你好Chris Meng，我没有修改过cache，状态改变的问题找到了，是发送完成后多加了一句IpcBitsInLink_putEmptyVideoBitStreamBufs(gIpcBitsInHLOSId,&emptyBitsBufList);

删掉之后状态就正常来～不过，出现了其它问题：

提示错误发生在Utils_quePut()函数里，我加了打印信息：

提示que is full，可为什么第一次提示时最大元素个数是0？
