* avformat/hlsenc: rename option from use_localtime to strftimeSteven Liu2018-09-05

* avformat/movenc: implicitly enable negative CTS offsets for ismvJan Ekström2018-08-24
| | | | | | | | | | | ISMV lacks any sort of edit list support, as well as tfxd is effectively the PTS of the fragment for most intents and purposes. Thus, if b-frames are requested without negative CTS offsets you end up with N frames' worth of delay (tfxd PTS plus the CTS offset of the first sample). Negative CTS offsets enable the first sample to have CTS=DTS, and thus a/v desync due to b-frame reorder delay is avoided.
* avformat/movenc: creating producer reference time (PRFT) boxVishwanath Dixit2018-05-29
| | | | | | | | | The producer reference time box supplies relative wall-clock times at which movie fragments, or files containing movie fragments (such as segments) were produced. The box is mainly useful in live streaming use cases. A media player can parse the box and utilize the time fields to measure and improve the latency during real time playout.
* avformat/dashenc: Added option for Segment file formatKarthick Jeyapal2018-05-28
| | | | | | | | Right now segment file format is chosen to be either mp4 or webm based on the codec format. This patch makes that choice configurable by the user, instead of being decided by the muxer. Also with this change per-stream choice segment file format(based on codec type) is not possible. All the output audio and video streams should be in the same file format.

* avformat/dashenc: addition of segment index correction logicVishwanath Dixit2018-04-17
| | | | | | | | | | | | | | The logic is applicable only when use_template is enabled and use_timeline is disabled. The logic monitors the flow of segment indexes. If a streams's segment index value is not at the expected real time position, then the logic corrects that index value. Typically this logic is needed in live streaming use cases. The network bandwidth fluctuations are common during long run streaming. Each fluctuation can cause the segment indexes fall behind the expected real time position. Without this logic, players will not be able to consume the content, even after encoder's network condition comes back to normal state.
* avformat/dashenc: segmentation at the configured segment duration rateVishwanath Dixit2018-04-17
| | | | | | | When use_template is enabled and use_timeline is disabled, typically it is required to generate the segments at the configured segment duration rate on an average. This commit is particularly needed to handle the segmentation when video frame rates are fractional like 29.97 or 59.94 fps.
* avformat/dashenc: replacing 'min_seg_duration' with 'seg_duration'Vishwanath Dixit2018-04-17
| | | | | | | | | There are use cases where average segment duration needs to be configured and muxer is expected to maintain the average segment duration. So, using the name 'min_seg_duration' will be misleading. So, changing the parameter name to 'seg_duration', where it can be minimum segment duration or average segment duration based on the use-case. The additional updates needed for this functinality are made the sub-sequent patches of this patch series.

* | movenc: Add an option for enabling negative CTS offsetsMartin Storsjö2017-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | This reduces the need for an edit list; streams that start with e.g. dts=-1, pts=0 can be encoded as dts=0, pts=0 (which is valid in mov/mp4) by shifting the dts values of all packets forward. This avoids the need for edit lists for such streams (while they still are needed for audio streams with encoder delay). This eases conformance with the DASH-IF interoperability guidelines.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
