calculate_quantisation()

int64_t calculate_quantisation ( raw_time_64  time, uint64_t  framerate, uint64_t  framerate_divisor = 1  )

inline

Grid-align the raw time to a frame grid, which can be fractional.

Note

for extreme values of framerate and framerate_divisor, the computation is approximative and will be µs-aligned.
