DM368 接 BT.1120 输入

Other Parts Discussed in Thread: TVP7002

您好,

  我们目前的方案是FPGA直接输出BT.112016bit YUV到DM368的VPFE的YIN[0-7] &CIN[0-7],看Davinci Linux VPFE Capture Driver User's Guide里VPFE接收 YUV data都有外部解码设备,我们的方案是没有的。看vpfe_capture.c里,好像必须最少要有一个sub device设备才能加载起来vpfe。请问目前我们这种连接方式怎么处理前端采集?我个人想法是使用TVP7002作为sub device,修改tvp7002驱动的初始化部分,让vpfe能正常加载起来,再配置isif,这样是否可行?谢谢!
