运行sample_venc示例后发现数据采集一段时间后就会出现[SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread [SAMPLE_COMM_VENC_GetVencStreamProc]-922: get venc stream time out, exit thread 而且每次采集数据时间也不相同有的长，有的短长的5,6分钟，短的几十秒，正常2，3分钟之后就采集不到数据了，cat  proc/umap/vi 发现中断计数也没有增加，但是当我把读取编码流的那段函数去掉后发现，vi是一直有输入的，当加上读取编码流后的代码后，就会出现问题，vi也没有输入了，也能帮我分析一下，什么原因

用的是sdk里的样例，运行后出现get vi frame err:0xa010800e，看手册说明是视频输入缓存为空，再看proc目录下的vi文件，发现Intcnt值为0 既没有发生过帧中断，不知道是那边问题，希望大家帮助一下
