Can we figure out this sample rate thing before this gets really

Please use rational values. Hardly anyone ever resamples to an
irrational number and it's also needed to do proper A/V sync.
While it's true that most real-life applications will be happy with a
(double) - it can not guarantee exactness and most (double)-precision
bugs are hard to trace/detect in the source.
ffmpeg provides a simple API - see their `rational.h`
static inline double av_q2d(AVRational a){
return a.num / (double) a.den;
}
