[DVDnav-discuss] [PATCH] fix dvdnav_convert_time to work for full range

[Reimar Döffinger]

Hello,
currently the calculation will use int and thus overflow for anything
larger or equal to 20 hours.
Not sure if this is the best/nicest way, personally I prefer to do this
kind of thing with the
result = hour >> 4;
result *= 10;
result += hour;
result *= 6;
result += minute >> 4;
result *= 10;
....
scheme, but this is the minimal change required.
