请教关于DM8148的HDVPSS子系统采集16bit YUV 4:2:2视频数据的配置问题?

设计使用FPGA+DM8148的视频采集处理方案,使用FPGA采集外部视频进行格式的转换,转换为内嵌同步信号(embedded syncs)的16bit YUV数据,数据输出到DM8148的视频采集的VIP0接口;请问

1)VIP0接口支持内嵌同步的16bit视频输入吗?

2)支持的话,要有哪些部分需要修改?

可以支持的,你的fpga输出按bt1120协议输出就可以,采集配置capure link 为 VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC 和 VPS_CAPT_VIDEO_IF_MODE_16BIT
