Hello. > +#define VIDIOC_S_COLOR_SPACE_CONV _IOW('V', 83, struct v4l2_color_space_conversion) > +#define VIDIOC_G_COLOR_SPACE_CONV _IOR('V', 84, struct v4l2_color_space_conversion) Do you mind if I ask a question about those ioctls? Because as far as I understand, we can use VIDIOC_S_FMT ioctl to convert colorspaces. Setting through colorspace member in v4l2_pix_format, we could change output colorspace. If there is some different use, can you tell me what it is? Regards, Nate -- ======================================================== Dong Soo, Kim Engineer Mobile S/W Platform Lab.
