Sinca build 5.2.458, recording start taime, end time and duration time are calculated by stream frames time stamps. note that RTMP stream timestamps are always starting from 0, but WebRTC publisher usually sets full time stamp by its own clock for ever frame.
To calculate recording times more preciosly, audio data should be buffered to keep synchronization. To do this, the following parameter is added
