Michael Niedermayer 4abc411b97 nutenc: choose for non audio streams a timebase with finer resolution.
While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.

This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise

Michael Niedermayer e3fb5bc147 nut: store and read the r_frame_rate
With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.
