* avfilter/drawtext: present 'hms' formatted 'pts' in 24h formatVishwanath Dixit2018-06-04
| | | | | | | | | | | | HMS is formatted as HH:MM:SS.mmm, but, HH part is not limited to 24 hours. For example, the the drawn text may look like this: 243029:20:30.342. To present the timestamp in more readable and user friendly format, this patch provides an additional option to limit the hour part in the range 0-23. Note: Actually the above required format can be obtained with format options 'localtime' and 'gmtime', but, milliseconds part is not supported in those formats.
