- Run analysis after all frames are processed. Before part of it was done at bitrate change points; - Analysis is done for whole stream as well as for each rate update interval; - Changed units from number of frames to time units for some metrics and thresholds. E.g. 'num frames to hit tagret bitrate' is changed to 'time to reach target bitrate, sec'; - Changed data type of FrameStatistic::max_nalu_length (renamed to max_nalu_size_bytes) from rtc::Optional to size_t. There it no need to use such advanced data type in such low level data structure.
