* 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>

* libavformat/hlsenc: default segment name and use_localtimeBela Bodecs2017-01-01

This %s specifier will insert the seconds since EPOCH. But %s is not available on all system/environment. This patch check %s availabilty at runtine and alter the default format string if necessary.

* 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 ....

Basically, the bug is that the last segment and the "#EXT-X-ENDLIST" tag are not being written to the subtitle playlist file when converting a file with subtitles to the HLS format. The reason for this seem to be that the filename for the subtitle file is being freed too early. This solution is simply to free that memory after it's last use in the "hls_window" function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

In addition, each filename in the playlist output will be prefixed with this subdirectory (if playlist and segment shares the same base path).

| * lavf: allow custom IO for all filesAnton Khirnov2016-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.
