HI, Following is the ffmpeg command used to stream the data.
ffmpeg -re -f avfoundation -framerate 30 -i 0 -codec:v h264_videotoolbox -x264-params keyint=120:scenecut=0 -codec:a copy -f hls -hls_list_size 60 -hls_time 10 -hls_flags delete_segments -hls_flags +append_list -hls_flags +discont_start -hls_flags +program_date_time -strftime 1 -strftime_mkdir 1 -hls_segment_filename '%Y%m%dT%H%M%S%z.ts' playlist.m3u8 Following is the playlist.m3u8 content which generated for a few seconds. #EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:10 #EXT-X-MEDIA-SEQUENCE:0 #EXT-X-DISCONTINUITY #EXT-X-DISCONTINUITY #EXTINF:10.000000, #EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:07:53.000+0530 20201109T220753+0530.ts #EXTINF:10.000000, #EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:08:03.000+0530 20201109T220803+0530.ts #EXT-X-ENDLIST When the re-stream happens(in case of restarting the streaming service), the program date time of older segments(before #EXT-X-DISCONTINUITY) also get changed like below which is unexpected. #EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:10 #EXT-X-MEDIA-SEQUENCE:0 #EXT-X-DISCONTINUITY #EXT-X-DISCONTINUITY #EXTINF:10.000000, #EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:12:50.633+0530 20201109T220753+0530.ts #EXTINF:10.000000, #EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:13:00.633+0530 20201109T220803+0530.ts #EXT-X-DISCONTINUITY #EXTINF:10.000000, #EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:13:12.000+0530 20201109T221312+0530.ts #EXTINF:5.400000, #EXT-X-PROGRAM-DATE-TIME:2020-11-09T22:13:22.000+0530 20201109T221322+0530.ts #EXT-X-ENDLIST Why does the program date time of older segments change? Should we add any arguments explicitly in ffmpeg command to handle this?
