Hi Monica, The v4l2-library is not the best mailinglist for that so I've added linux-media as well, which is more appropriate. I've also added Lars-Peter since he does a lot of adv work as well. The short answer is that those colorspaces are not supported at the moment, but that it is not a problem to add them, provided the driver you are working on is going to be upstreamed (i.e., we'd like to have users for the API elements we add). One note of interest: there is currently no API mechanism to tell userspace if the image data is limited or full range. YCbCr is always assumed to be limited range and RGB full range. If you need to signal that, then let me know. A flags field has been added to struct v4l2_pix_format in the last few days that would allow you to add a 'ALT_RANGE' flag, telling userspace that the alternate quantization range is used. This flag doesn't exist yet, but it is no problem to add it. Hope this helps, Hans On 07/22/14 08:18, Monica, Agnes wrote: > Hi , > > One of drivers which we are developing supports formats like sYcc , > AdobeRGB and AdobeYCC601 which was added recently in HDMI spec1.4.
