#4048: segment: Handle WebVTT as per HLS spec -------------------------------------+------------------------------------ Reporter: 11rcombs | Owner: Type: enhancement | Status: new Priority: normal | Component: avformat Version: git-master | Resolution: Keywords: hls webvtt | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------ Comment (by Djfe): I guess this kinda belongs to this ticket: https://amd.cdn.turner.com/adultswim/episodes/no_uk_geo/bobsburgers/2017/03/... is the webvtt Stream (subtitle only stream) related to https://amd.cdn.turner.com/adultswim/episodes/no_uk_geo/bobsburgers/2017/03/... from http://www.adultswim.com/videos/bobs-burgers/the-itty-bitty-ditty- committee/ Though I'm not sure. If this is only an issue about the muxer but not the demuxer, then say so and I'll open a new ticket. FFmpeg only saves the first segment instead of merging all segments together, like it's described in this ticket. ffmpeg -i url -c copy example.vtt Since the m3u8 won't be up forever, here's the content of it: {{{ #EXTM3U #EXT-X-VERSION:3 #EXT-X-TARGETDURATION:300 #EXT-X-MEDIA-SEQUENCE:1 #EXT-X-PLAYLIST-TYPE:VOD #EXTINF:300.299, bobsburgers_cc_505_Digital_IttyBittyDittyCommittee_stream_webvttvtt_00001.vtt #EXTINF:300.300, bobsburgers_cc_505_Digital_IttyBittyDittyCommittee_stream_webvttvtt_00002.vtt #EXTINF:300.300, bobsburgers_cc_505_Digital_IttyBittyDittyCommittee_stream_webvttvtt_00003.vtt #EXTINF:300.300, bobsburgers_cc_505_Digital_IttyBittyDittyCommittee_stream_webvttvtt_00004.vtt #EXTINF:104.104, bobsburgers_cc_505_Digital_IttyBittyDittyCommittee_stream_webvttvtt_00005.vtt #EXT-X-ENDLIST }}} FFmpeg only saves the first 5mins, so I guess that's the segment time. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4048#comment:5> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
