STM32F407与TVP5150调试模拟视频转换并显示全是黑屏

之前都是使用STM32F10系列的单片机做小项目
最近想做视频方面的，给模拟视频转换并显示，看到TVP5150，但大部分是 arm开发板带的模块。
由于只做视频，再买个ARM太浪费了，看到STM32新品中4系列有DCMI接口，刚好TVP5150能输出YCBCR数据流（可惜如果输出RGB就更好了）。
调试了三周左右，视频一直没有出来，但别人说配置几个寄存器就行了，可我的就是不行。全是黑屏，如果输出嵌入式同步信号，接收部分选择分离同步信号，屏幕上还有同步的斑点。数据接收没有问题。
昨天我用逻辑分析仪分析输出信号，拿掉了几根数据线，屏幕居然出现了图像！！！
全接上又没有了，接的数据线多少和图像的持续时间有关！！！
这个会不会是高频信号的干扰？（我用杜邦线飞到开发板上的）
还可能是TVP5150的数据输出能力与 STM32数据接口的配置
谁有过这样的经验？我的TVP5150模块在ARM嵌入式开发板淘宝店买的。
