Hi all,
We are working on a camera driver. We plan to use v4l2 interface to send
image data to users. We have a question we'd like to ask.
The situation we are facing is as follows.
We have an image processing unit that can process raw data collected by
the sensor into the V4L2_PIX_FMT_NV12M format and send it to the user.
However, due to the requirements of the V4L2_PIX_FMT_NV12M format, the
width and height of the image must be divisible by 16.
For example, when the sensor provides an image size of 2104x1560, after
NV12M encoding, it should be pading to 2112x1566. But the additional 8
rows and 8 columns are padded with 0s and contain no actual content.
So, we would like to ask, in this case, what size should we list in
VIDIOC_ENUM_FMT? Should it be the actual image size with content,
2104x1560, or the padded size, 2112x1566?"
Thank you,
Zhaoxuan
