I think movie source should keep original time, let next filter to determine
how to use these frame. if next filter need monotonically increasing timestamp,
it can insert setpts filter or other filters to fix timestamp. In the
movie source,
when rewind,   we are difficult to determine first frame's timestamp.

others are updated. Please check again.
