This is empiric tuning to avoid bitrate peaks above maximum bandwidth.
c->bit_rate is a mean bitrate.
When doing real-time encoding, rate control cannot be deterministic.
As bitrate peaks are disastrous for user experience (ugly video frames, slowing down), this 0.7 factor try to make this to never happen.
