  All of them are like that.
  I’m a newb and don’t know how to solve this. They’re right next to each other.
  Any suggestion is appreciated. Thank you.

• Anomalie #4189 : extraire_multi mélange un /li /ul final avec le de langue ajouté par code_...

  17 novembre 2018, par jluc -

  Ce bug révèle peut être un pb conceptuel dans la manière qu’a extraire_multi de parfois ajouter des div en début et fin de texte lors de ses traitements intermédiaires. Ç’a peut être été conçu à l’origine avec l’idée qu’il n’y aurait que des éléments inlines dans une chaîne traitée, et pas de balises html, alors que maintenant il y a des blocs et des balises. Et l’astuce initiale, qu’on peut qualifier de hack, se trouve devenue foireuse dans certains cas.

• MP4Box does not create final segment

  5 janvier 2019, par Dhruva

  MP4Box is not creating the final segment of video when I dash it. If I run this command on the command line I get only 15 segments out of 16(there is no error) and running it in Google’s Shaka player gives me a 404 at the end of the video saying that the 16th video segment is not found. I am running MP4Box version 0.5.2.

  MP4Box -dash 4000 -rap -frag-rap -sample-groups-traf -profile dashavc264:live -bs-switching multi -url-template video-700k-encrypted.mp4 video-1000k-encrypted.mp4 video-1500k-encrypted.mp4 video-2000k-encrypted.mp4 audio-encrypted.mp4 -out "dash_protected/manifest.mp4"
