Hi, i'm trying to sync webVTT subtitles with HLS video. my process: 1. segment the mp4 to 10sec segments 2. repeat step 1 for multiple renditions * these steps are done by using the script found here: https://gist.github.com/mrbar42/ae111731906f958b396f30906004b3fa 3. segment the webVTT file and update the master playlist with the subtitles info. * using this command: ffmpeg -i SOURCE -f segment -segment_time 10 -segment_format webvtt -scodec copy -segment_list PLAYLISTNAME-sub.m3u8 -segment_list_type m3u8 SEGMENTNAME-%d.vtt
problem: subtitles are not synced with video/audio cause: i noticed that my VOD script changes the video start time and my first segment of the video gets pkt_pts = 133200 , whereas in the original video it starts with 0. i'm not sure if a.i should force my script to set the initial ts to 0 - was not able to accomplish that b. add an offset to my VTT files. - seems really strange that i would have to ffprobe each segmented video for pkt_pts value and then edit my VTT files accordingly. what am i missing? is there an easier way to achieve this? Thanks. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
