1. 我们现在是做红外摄像机的,FPGA输出的16bit,YUV422数据给视频前端。但是这个代码工程是用的 TVP5150 解码然后输出8bit,YUV420数据,不知该如何下手将 TVP5150 修改为 FPGA?
       (1)代码里将TVP5150加入到了视频前端的子设备内:
                        vpfe_subdev_info  vpfe_sub_devs[ ] = {
                                                                                             {
                                                                                                      .module_name = "tvp5150",
                                                                                                      .grp_id = VPFE_SUBDEV_TVP5150,
                                                                                                      .inputs = tvp5150_inputs,
                                                                                                      .routes = tvp5150_routes,
                                                                                                      .ccdc_if_params = {
                                                                                                                                             .if_type = VPFE_BT656,
                                                                                                                                             .hdpol = VPFE_PINPOL_POSITIVE,
                                                                                                                                             .vdpol = VPFE_PINPOL_POSITIVE,
                                                                                                                                    },
                                                                                                      .board_info = {   I2C_BOARD_INFO("tvp5150" , 0x5d)    }
                                                                                              }
                                                                                      }
          TVP5150通过挂载在 I2C 上,现在不需要TVP5150 和 I2c ,不知如何将FPGA加载到子设备中。
 
  希望朋友能指导一下!

感谢你的回复,我仔细看了一下,还是没得到解决办法。

我现在是采集线程内采集不到数据,而且open设备文件失败,不知这个设备文件是如何创建的?
