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。

==========================================================================================

tw9990:ioctl_g_ifparm
clock_curr=mclk=0
Returning size of 960x625
g_fmt_cap returns widthxheight of input as 960 x 625
