As a sideeffect this simplifies the equation, the high bits are different after this but only
the low 16bits are stored and used in later steps.

When tak_get_nb_samples() fails, it will currently write
AVERROR_INVALIDDATA as TAKStreamInfo.frame_samples. The parser will then
use this negative value as a frame duration, which leads to various
breakage.
Avoid this by returning the error code from tak_parse_streaminfo()
directly; never store negative values in the parsed header.
One that is fine enough to represent all DV audio sample rates. Audio
packet durations are now sample-accurate.
This largely undoes commit 76fbb0052d. To
avoid breaking the issue fixed by that commit, resync audio timestamps
against video if they get more than one frame apart. The sample from
issue #8762 still works correctly after this commit.
Slightly changes the results of the lavf-dv seektest, due to the audio
timebase being more granular.
Current 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 fine enough to
handle all supported DV framerates.
The seek tests change slightly because the new timebase is more
granular.
