1st: 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 2nd: doc/muxers: beside second_level_segment_duration and second_level_segment_size, added some more details and example to hls_segment_filename, use_localtime, use_localtime_mkdir, hls_flags. hls_flags option list reformatted to table Signed-off-by: Bela Bodecs <bodecsb@vivanet.hu> Signed-off-by: Steven Liu <lq@chinaffmpeg.org>
