Hi,
Recently, I try to use a raw8 grey sensor on rv1106 platform.
From the rv1106 datasheet, the vicap support YUV400SP format output.
But when I try to set vi and venc to YUV400sp
vi_chn_attr.enPixelFormat = RK_FMT_YUV420SP;
stAttr.stVencAttr.enPixelFormat = RK_FMT_YUV420SP;
it tell me
RTDeviceV4L2 13:05:57-820 {ispInitFormat :697} pixFormat:b not support.

Hello, please use the v4l2-ctl command to check whether the sensor you are using supports input in the format you specify. ,
At the same time, according to the MPI document, although RV1106 does not have a support list description on the VENC component, other models do not support outputting to YUV400SP or encoding YUV400SP into a compressed format. Format conversion is mainly implemented using VPSS. The output of YUV400SP is also mentioned in the description of the VPSS component. Please try to use the VPSS component to achieve it.

Thank you very much. I am sure my sensor output raw8 gray image. If I set Vi to YUV420SP， it is noraml, but If I set to YUV400SP, it is failed.
what I want to do is send the YUV400SP to jpeg encoder but the encoder seems does not support YUV400SP
