达芬奇A8传递数据给M3时BUFSTATE改变？

tony gan

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

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）：

Tony，

你有修改过memory map/bld/cache相关的部分？

会不会和cache相关？

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：

[m3video] 15495: Assertion @ Line: 1312 in links_m3video/iva_dec/decLink_common.c: status == FVID2_SOK : failed !!!

提示错误发生在Utils_quePut()函数里，我加了打印信息：

Int32 Utils_quePut(Utils_QueHandle * handle, Ptr data, Int32 timeout)
{
    Int32 status = -1;                                     /* init status to
                                                            * error */
    UInt32 cookie;

    do
    {
        cookie = Hwi_disable();

        if (handle->count < handle->maxElements)
        {
            handle->queue[handle->curWr] = data;

            handle->curWr = (handle->curWr + 1) % handle->maxElements;

            handle->count++;

            Hwi_restore(cookie);

            status = 0;

            if (handle->flags & UTILS_QUE_FLAG_BLOCK_QUE_GET)
            {
                Semaphore_post(handle->semRd);
            }

            break;

        }
        else
        {

           Vps_printf("###chenh<encdec>>> %s:que is full,request %d >= max %d",__func__,handle->count,handle->maxElements);

           Hwi_restore(cookie);

            if (timeout == BIOS_NO_WAIT)
                break;

            if (handle->flags & UTILS_QUE_FLAG_BLOCK_QUE_PUT)
            {
                Bool semPendStatus;

               handle->blockedOnPut = TRUE;
                semPendStatus = Semaphore_pend(handle->semWr, timeout);
                handle->blockedOnPut = FALSE;
                if (!semPendStatus || handle->forceUnblockPut)
                {
                    handle->forceUnblockPut = FALSE;
                    break;
                }
            }
            else
            {
                break;
            }
        }
    }
    while (1);

    return status;
}
然后，日志输出：

提示que is full，可为什么第一次提示时最大元素个数是0？
