Hans any opinion ? I think commas are hard to parse. Note that v4l_getsubopt is normally a #define for getsubopt from glibc. So you can't change the behavior of that function. I propose this format for parsing instead: widthxheight@(top;left) e.g.: 1000x2000@(0;0) According to this: https://www.dr-aart.nl/Geometry-coordinates.html the ';' is the separator in countries where a decimal comma is used instead of a decimal point. I prefer to have the position after the size of the rectangle, for two reasons: it feels more natural to talk about a 'rectangle of size S at position P', and it also makes it possible to allow a variant where only the size is given and the position will default to (0;0). I.e., we can support parsing either "widthxheight" or "widthxheight@(top;left)". However, logging rectangles in the kernel should use a comma instead of a semicolon. Inside v4l-utils just consistently use the semicolon. What do you think, Laurent?

I would very strongly like to avoid that. Have we used that notation in the kernel? Where? I will admit that I am not a fan of the media-ctl notation, I think it is weird. I think WxH@(x,y) is much more natural. But if v4l_getsubopt can be adapted for this, then I'm fine with it.
