>>>> Dear All,
>>>>> this patch makes it possible to put actual segment file size (measured
>>>>> in bytes) and/or duration (calculated in microseconds) into segment
>>>>> filenames. This feature is useful when post-processing live streaming
>>>>> access log files. New behaviour works only when -use_localtime option
>>>>> is set and second_level_segment_size or/and
>>>>> second_level_segment_duration new hls_flags are specified. %%s is the
>>>>> placeholder for size and %%t for duration in hls_segment_filename
>>>>> option. Fix sized trailing zeropadding also works eg. %%09s or %%023t.
>>>>>
>>>>> A command to test new features:
>>>>> ./ffmpeg -loglevel info -y -f lavfi -i color=c=red:size=640x480:r=25 -f
>>>>> lavfi -i sine=f=440:b=4:r=44100 -c:v mpeg2video -g 25 -acodec aac
>>>>> -cutoff 20000 -ac 2 -ar 44100 -ab 192k -f hls -hls_time 3 -hls_list_size
>>>>> 5 -hls_flags
>>>>> second_level_segment_index+second_level_segment_size+second_
>>>>> level_segment_duration
>>>>> -use_localtime 1 -use_localtime_mkdir 1 -hls_segment_filename
>>>>> "segment_%Y%m%d%H%M%S_%%04d_%%08s_%%013t.ts" stream.m3u8
>>>>>
>>>>> this will produce segments like this:
>>>>> segment_20170102194334_0003_00122200_0000003000000.ts
