| | | | | | | | | | | | | | Return a channel layout and the number of channels based on the specified name. This function is similar to av_get_channel_layout(), but can also parse unknown channel layout specifications. Unknown channel layout specifications are a decimal number and a capital 'C' suffix, in order to not break compatibility with the lowercase 'c' suffix, which is used for a guessed channel layout with the specified number of channels.

* avformat/hlsenc: hls_start_number_source and start_numberBodecs Bela2017-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* avformat/hlsenc: size and duration in segment filenamesBela Bodecs2017-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* avformat/hlsenc: strftime identifiers and segment indexBodecs Bela2016-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 segment_20161227005903_00016.ts segment_20161227005903_00017.ts segment_20161227005903_00018.ts segment_20161227005903_00019.ts segment_20161227005903_00020.ts ....
