视频处理芯片是TP9950,CVBS进来的转换BT656,如果分辨率720x576是没有问题的,但是TP9950输出分辨率改为960x576时,驱动ioctl_g_fmt_cap返回960x576会出现如下错误,提示不支持。

感谢你提供的连接,这个文档我看了2遍,没找到关键有用信息。
用720x576是可以显示摄像头画面,如下,但是右边没有显示全。改成960x576后,提示“imx-ipuv3 imx-ipuv3.0: Unsupported CCIR656 interlaced video mode”错误
When the camera you change to 960x576, you also can try to set the display to support this display.
You can see this https://community.nxp.com/docs/DOC-332679 to adjust your board.
