• Evolution #3179 : Pouvoir désactiver l’héritage de logo entre les rubriques (via une constante)

  5 mars 2014, par - Equipement

  Une solution consisterait à modifier, dans le fichier ecrire/public/quete.php, la fonction quete_logo, en remplaçant :

          else if ($id_rubrique) 
              $type = ’id_rubrique’ ;
              $id = $id_rubrique ;
              $id_rubrique = 0 ;

  par :
  

          else if (defined("_DESACTIVER_HERITAGE_LOGO_RUBRIQUE"))
              return ’’ ;
          else if ($id_rubrique) 
              $type = ’id_rubrique’ ;
              $id = $id_rubrique ;
              $id_rubrique = 0 ;

• Anomalie #2327 : Voir le logo du site dans l’espace privé

  25 octobre 2011, par tetue -

  Pourquoi pas, mais ce serait plutôt ’edition’, car il s’agit d’éditer (le descriptif, etc.) et non de publier le site. On peut essayer, mais ça n’est pas choquant que ça reste à sa place habituelle. C’est surtout l’entrée ’Plugins’ qu’il faut déplacer dans ce menu, pour marquer la séparation entre (...)

• Is it possible using FFMPEG to replace one ".ts" file in a HLS ts file collection with another ".ts" file ?

  27 juillet 2019, par Vadim

  There is a video, actually an HLS stream (sequence of TS files)
  I would like to take out one TS chunk and replace it with another.
  Another chunk will be encoded using same FFMPEG encoding settings.

  In case you wonder why i need this :
  There is a five hours HLS stream. One of TS has a wrong title on the video. I need to change that TS without re-encoding the whole HLS stream.

  Currently i tried :

  1. Take TS and convet it using FFMPEG into mp4
  2. Edit mp4 video (change title) and save as new mp4
  3. Convert new mp4 into new TS (using FFMPEG, same settings as was used for original video)
  4. Replace original TS with the new TS.

  But it doesn’t work, player shows loading in progress icon. (in the network console i see that this new TS is loaded normally, with status 200)

  As soon as i replace new TS with original one, player plays it normally.

  Both TS files start with I-frame, both have audio. There’s only a slight difference in the sequence of P and B frames.

  How can i get new TS chunk working in original TS sequence ?

  Update :

  As per szatmary advice (below) i tried to include "-copyts" flag during all ts>mp4>ts conversions. Also tried "-copytb" flag with all 3 options -1, 0, and 1. However result still the same - player doesn’t play HLS TS sequence (m3u8) with new TS chunk.

  Adding "#EXT-X-DISCONTINUITY" tag after replaced TS in the M3U8 list, doesn’t fix the situation.

  Without "#EXT-X-DISCONTINUITY" tag, player gives error :

  VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) There appears to be a playback issue.
  
  
  
  code: 4

  With "#EXT-X-DISCONTINUITY" tag, player gives error :

  VIDEOJS: ERROR: (CODE:3 MEDIA_ERR_DECODE) There appears to be a playback issue.
  
  
  
  code: 3

  Both TS files (old one and new one) have video and audio streams.

  Looks like something else should be done. I think solution will be similar to ad insertion.
