DM8148 DEI link 与 CaptureLink 数据交互的疑问

DM8148分别对7002和5158模块同时进行视频采集,CaptureLink中有2个instance,一个用于7002,另一个用于5158,CaptureLink的下一个link就是DEI link,由于5158采集的PAL视频需要经过去隔行处理,因此CaptureLink下一个link必须是DEI link,但是由于CaptureLink中又包含了VGA的视频数据,这个是不需要去隔行处理的,然而在DEI link的参数中没有找到可以针对某个输入的CaptureLink进行使能去隔行或失能去隔行的开关变量,也就是说,CaptureLink传入DEI link的视频数据,要么全部被去隔行处理,要么被旁路处理,这就导致5158和7002采集到的视频无法同时处理,有什么好的解决方法吗?

Chris Meng：

你好，

1. 标清可以不去隔行，在编码的时候使用隔行编码。

2. 请问两路采集是用的两个VIP口么？如果是，两个VIP口输出可以接不同的link吧。
