Those differences are described in this section. We will -have to see whether we need to adjust the spec or not. - -1) It is no longer required to have all controls contained in a -v4l2_ext_control array be from the same control class. The framework will be -able to handle any type of control in the array. You need to set ctrl_class -to 0 in order to enable this. If ctrl_class is non-zero, then it will still -check that all controls belong to that control class. - -If you set ctrl_class to 0 and count to 0, then it will only return an error -if there are no controls at all. - -2) Clarified the way error_idx works. For get and set it will be equal to -count if nothing was done yet. If it is less than count then only the controls -up to error_idx-1 were successfully applied. - - Proposals for Extensions ======================== |
