Subject: [PATCH] matroskadec: use uint64_t instead of int for index_scale

index_scale is set to matroska->time_scale of type uint64_t.

When index_scale is int, the assignment can overflow and e.g. result
in index_scale = 0. This causes a floating point exception due to the
division by index_scale.
