The code will call avpriv_set_pts_info() for each video frame, possibly
setting a different timebase if the stream framerate changes. This
violates API conventions, as the timebase is supposed to stay constant
after stream creation.
Change the demuxer to set a single timebase that is granular enough to
handle all supported DV framerates.
The seek tests change slightly because the new timebase is more
granular.
Just because the timebase is more granular the packet timestamps should
not change.
