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 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
