  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • delay between subtitles and video/audio hls ffmpeg videojs

    16 juillet 2020, par Maxou

    I use ffmpeg to convert video to hls format (m3u8) and I use videojs to read this video. But I have a problem, subtitles appeared 1.4 seconds before the real timestamp.

    


    I execute this command to extract video, audio and subtitles :

    


    ffmpeg -i [file] -map 0:1 -c:a aac -ar 48000 -b:a 320k -hls_time 2 -hls_segment_filename audio/1/seq-%d.ts audio/1/320kbit.m3u8 -map 0:2 -c:a aac -ar 48000 -b:a 320k -hls_time 2 -hls_segment_filename audio/2/seq-%d.ts audio/2/320kbit.m3u8 -map 0:s:0 -f webvtt sub.vtt -map 0:v:0 -vf scale=1920:-2 -c:v h264 -profile:v main -g 48 -keyint_min 48 -crf 20 -sc_threshold 0 -b:v 5000k -maxrate 5350k -bufsize 7500k -hls_time 2 -hls_segment_filename video/1080p/seq-%d.ts video/1080p/5000k.m3u8


    


    And this command to convert substile to hls format

    


    ffmpeg -i sub.vtt -f segment -segment_time 2 -segment_list_size 0 -segment_list my-hero/subtitles/sub.m3u8 -segment_format webvtt -scodec copy my-hero/subtitles/seq-%d.vtt


    


    And then I create a playlist file to gather all of that

    


    #EXTM3U
#EXT-X-VERSION:3

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio-group",LANGUAGE="fre",NAME="Français",DEFAULT=YES,AUTOSELECT=YES,URI="audio/1/128k.m3u8"
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio-group",LANGUAGE="jpn",NAME="Japonais",DEFAULT=NO,AUTOSELECT=YES,URI="audio/2/128k.m3u8"

#EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",NAME="Français",DEFAULT=yes,AUTOSELECT=YES,FORCED=NO,LANGUAGE="fr",URI="subtitles_fr.m3u8"

#EXT-X-STREAM-INF:BANDWIDTH=5000000,RESOLUTION=1920x1080,SUBTITLES="subs",AUDIO="audio-group"
video/1080p/5000k.m3u8


    


    I don't see the problem so if anyone have an idea :/

    lavf/hls : add http_seekable option for HTTP partial requests

    Add http_seekable option for HTTP partial requests, when The
    
EXT-X-BYTERANGE tag indicates that a Media Segment is a sub-range
    
of the resource identified by its URI, we can use HTTP partial
    
requests to get the Media Segment.
