我们现在的DM385开发板上外挂了一个tvp5151芯片，用来接CVBS摄像头，原理图如下：
tvp5151输出8bit 内嵌同步的CVBS(NTSC或PAL)信号到DM385的VIP1 PORTA的D0~D7位上，数据流如下：
tvp5151(cvbs) -> capture-> deinterlace -> encode -> send
软件版本使用的是dvr rdk 4.0，代码如下：

测试结果如下：
1. 当“pCaptureInstPrm->standard = SYSTEM_STD_D1”时，capture采不到视频；
2. 当“pCaptureInstPrm->standard = SYSTEM_STD_MUX_4CH_D1”时，capture可以采到视频，但deinterlace会出错；
麻烦各位帮忙看一下上面的哪些配置是错误的，到底该怎么配置才能让视频出来？ 谢谢！
