Hi all, As a summar from the discussion, I think we have reached the following conclusion. Please say if you agree or disagree with what's below. :-) - The drivers will be moved to use monotonic timestamps for video buffers. - The user space will learn about the type of the timestamp through buffer flags. - The timestamp source may be made selectable in the future, but buffer flags won't be the means for this, primarily since they're not available on subdevs. Possible way to do this include a new V4L2 control or a new IOCTL.
