• FFMPEG & JNI : How to decode from URL

  24 avril 2013, par Hafedh Haouala

  I'm trying to make an android application that uses the FFMPEG for decoding videos that are not supported by Android ( not on all the devices at least ) : MPEG-TS & h264 Main Profile.
  So, until now, I was able to use FFMPEG from JNI to decode some local video with the above specs, but my goal is to make the FFMPEG decode data from a streaming URL (http://127.0.0.1:1666/) on which I will send buffers from an android service (for certain reasons)

  So, basically, I have two questions :

  • how I will be able to do the decoding from a streaming URL as I couldn't find any good example ?

  • when decoding my local MPEG-TS video, I've noticed that the playback speed is quite slow, and it happen that the video freezes for a while, even the Dolphin Player (based on FFMPEG) has the same behavior, and I don't know if is there some solution for this. Any suggestion ?

  I appreciate your help.

• Evolution #4637 (Fermé) : Jointure inutile pour critère "extension"

  21 janvier 2021, par jluc -

  La boucle suivante
  

  ’tout>

  
  produit un MYSQL simple :
  

  SELECT documents.fichier
  FROM spip_documents AS `documents`
  WHERE (documents.taille > 0 OR documents.distant=’oui’)
      AND (documents.extension  IN (’png’,’jpg’,’gif’))
  ORDER BY FIELD(documents.extension,’png’,’jpg’,’gif’)
  

  Si à la boucle on ajoute une jointure avec un objet :
  

  ’toutobjet=articleid_objet=3>

  
  une jointure supplémentaire avec la table spip_types_documents apparaît :
  

  SELECT documents.fichier
  FROM spip_documents AS `documents`  
  INNER JOIN spip_documents_liens AS L1 ON ( L1.id_document = documents.id_document )
  WHERE (documents.taille > 0 OR documents.distant=’oui’)
      AND (documents.extension  IN (’png’,’jpg’,’gif’))
      AND (L1.objet = ’article’)
      AND (L1.id_objet = 3)
  GROUP BY documents.id_document
  ORDER BY FIELD(documents.extension,’png’,’jpg’,’gif’)
  

  Il me semble que cette jointure n’est pas plus utile pour cette 2eme boucle que pour la première et ne devrait pas être ajoutée.
