606eac7b07 avformat/hlsenc: add hls_flag option to write segments to temporary file until complete
Adds a `-hls_flags +temp_file` which will write segment data to
filename.tmp, and then rename to filename when the segment is complete.

This patch is similar in spirit to one used in Plex's ffmpeg fork, and
allows a transcoding webserver to ensure incomplete segment files are
never served up accidentally.

8811d6d9a0 avformat/hlsenc: hls_start_number_source and start_number
start_number option starts the playlist sequence number
(#EXT-X-MEDIA-SEQUENCE) from the specified number. Unless hls_flags
single_file is set, it also specifies starting sequence numbers of
segment and subtitle filenames. Sometimes it is usefull to have unique
starting numbers at each run, but currently it is only achiveable by
setting this parameter manually.
This patch enables to specify start_number source parameter by
introducing hls_start_number_source with 3 possible values:
generic/epoch/datetime. This ensures to set start sequence number
automatically for practically unique numbers. Generic option is the
default and this is the curent behaviour: start_number option value
specifies the start sequence number. (start_number default value is 0)
If hls_start_number_source is set to epoch, then the start number will
be the seconds since epoch (1970-01-01 00:00:00). If set to datetime,
then the start sequence number will be based on the current date/time
value as YYYYmmddHHMMSS. e.g. 20161231235659.
Hls speficication allows 64 bit integers as sequence numbers. This patch
also changes some code where only 32 bit integer values were handled
correctly.

557c0df9a8 avformat/hlsenc: size and duration in segment filenames
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

0ff8c6b6d5 avformat/hlsenc: strftime identifiers and segment index
in filenames

Putting date/time values into segment filenames is very usefull.
But to produce non-conflicting segment filenames with -use_localtime
option with date/time
values in hls_segment_filename option, sometimes is not enough.
Like in cases when multiple segments produced in the same second.
But hlsenc currently does not make possible to use segment index (%d) at
the

same time whe use_localtime is in effect, due to identifier conflict.
This patch makes possible to use strftime identifiers and still put
segment index (%d) at same time in segment filenames by introducing
second_level_segment_index flag. When -use_localtime is active,
identifier %d is for month day index, so %%d is the segment index
placeholder. This enhanced behaviour only exists when new
second_level_segment_index flag is specified.
For instance putting 'segment_%Y%m%d%H%M%S_%%05d.ts' value into
-hls_segment_filename option and specifing -hls_flags
second_level_segment_index and -use_localtime 1, may produce segment
filename as 'segment_20161230235758_00002.ts'

An example:

ffmpeg -loglevel info -y -f lavfi -i color=c=red:size=640x480:r=25 -f
lavfi -i anullsrc=r=44100:cl=stereo -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 delete_segments+second_level_segment_index -use_localtime 1
-hls_segment_filename "segment_%Y%m%d%H%M%S_%%05d.ts" stream.m3u8

will produce segments filenames:

....
segment_20161227005902_00013.ts
segment_20161227005902_00014.ts
segment_20161227005902_00015.ts
