请教一下各位大神，V853怎样实现连续解码多个ts文件，中间不断流？

[yu741373252]

我的想法是在demux解码完上一个文件直接加载下一个文件，刚好看到全志有AW_MPI_DEMUX_SwitchDateSource这个函数，但是我测试的AW_MPI_DEMUX_SwitchDateSource函数一直返回-1，不知道什么原因，有哪位大神使用过AW_MPI_DEMUX_SwitchDateSource，帮忙解答一下白，感恩感恩！！！

{
    switch (event)
    {
        case MPP_EVENT_NOTIFY_EOF:
        {
        	int ret = 0;
        	//char path[256] = {0};
            LT_LOGD("demux to end of file");
			if(pContext->mDmxChn >= 0)
			{

我另起一个线程，收到demux的EOF后延时一秒在AW_MPI_DEMUX_SwitchDateSource是可以的
