NetBSD people sent a fix to the upstream mailing list (see URL).

Patch from NetBSD people.

seems a bit overkill to use a callback and count by themselves the row number when the function 'png_get_current_row_number' exists...
could you please explain me ?

Sorry I can't explain that as I simply took the patch NetBSD is using. According to the mail correspondence in URL, upstream has already pushed a fix into their VCS. Maybe that fix is better that the one from NetBSD.

This should be fixed in mjpegtools-2.0.0_rc1 please reopen if there are still issues.
