Saxon 4aa71e901c codec/h264/h264dec: put function parameters on one line for parseTotalCoeffAndTrailingOnes 2019-09-09 16:41:26 +09:30
Saxon 61a5065556 codec/h264/h264dec: added functions to get TrailingOnes and TotalCoeff as well as testing 
The functions firstly derive the value of nC and then read the value of coeff_token from the BitReader. The table read prior and loaded into
a 'map' is then used to get the corresponding values of TrailingOnes and TotalCoef.

Saxon 817cc86a34 revid: now have MinPeriod and ClipDuration params 
This change included a rename of IntraRefreshPeriod to MinPeriod, and the addition of the ClipDuration param. PSI are now written before IDR. Clips are no longer outputed
based on PSI but rather a time ClipDuration, where ClipDuration >= MinPeriod, however, PSI must still be at the beginning of each clip. Also created functionality to update
meta time even if we don't have a response to update.
