hi3516a+adv7611视频输入

后面找到原因是ADV7611配置的是视频同步方式为外同步。而hi3516a默认的是内同步方式。

你是把ADV7611转换后的BT1120信号 通过MIPI接口输入到3516的吗？

是的，adv7611转换成bt1120后，用mipi接口接到hi3516a。

用mipi接口接到hi3516a

楼主您好，我现在adv7842接到3516的mipi，使用sample_venc测试，VI没有中断，和您当初的问题一样，我在配置了7842内同步之后还是无中断，可以给我看一下您7611的寄存器的配置吗，我参考一下，7842与7611寄存器区别不大。谢谢！

}

我是从这里下载下来的，基本没有改到，只是改了IIC读写。

对， 把我搞晕了。他应该是复用成BT1120接口了

你好，你这个7611的驱动是不是可以正常使用的了，谢谢！  我看到这个配置是 8bit  DDR mode  (bt656 mode )  bt1120 应该是 SDR 16 (20) bit   mode
adv7611_write(0x98, 0x03, 0x80); // 8-bit 4:2:2 DDR mode 2 (ITU-656 mode)

认真学习了下
