* Swresample can buffer data if more input has been provided than available
* output space, also converting between sample rates needs a delay.
* This function returns the sum of all such delays.
+ * The exact delay is not neccessarily an integer value in either input or
+ * output sample rate. Especially when downsampling by a large value, the
+ * output sample rate may be a poor choice to represent the delay, similarly
+ * for upsampling and the input sample rate.
