• Anomalie #3436 (Nouveau) : Forum : id_thread = 0

  5 mai 2015, par Debondt Didier

  Si j’utilise l’API objet pour créer des éléments de forum, sans spécifier explicitement un id_thread :

  $id_forum = objet_inserer(’forum’, null, $c) ;
  

  Il est possible que le champ id_thread soit égale à 0. Hors cela ne devrait jamais être le cas, il devrait à minima être égale à id_forum.

• How to encode downloaded m3u8 video using ffmpeg ?

  8 décembre 2014, par Patrick Alessi

  I have found a lot of guides to download and convert live streams using ffmpeg.
  My problem is that i have downloaded a tv show using the video downloader app for ipad, transfarred the .ts files and m3u8 file to my mac.

  How do I convert it into an mp4 og mkv file using ffmpeg now that the files are located on my local hard drive ?

  I have tried converting each clip with a video converter but they are rendered with gaps, and other problems...

  I need it to play as smooth as on an ipad but on my mac.

  I have no idea how ffmpeg works. I just follow a tutorial to make the installation. and i dont know how to set up virtuel servers...

• Possible to stream video over 115kbps ?

  15 mai 2014, par Arcadio Alivio Sincero

  I need some advice from people experienced with streaming video.

  I have a task to put together a system that allows video coming from RS-170 (composite) video cameras and have them displayed on an iPad. The catch is that no wireless (no Wi-Fi, no bluetooth) is allowed. Only a wired interface.

  The physical I/O options on an iPad are apparently extremely limited, but I did manage to come across a company named Redpark that makes an RS232-to-Lightning cable. So my proposed solution is to have the video feeds go into a box with software that digitizes and encodes the video, and then sends it over RS232 to the iPad using that cable. The catch here is that the maximum bandwidth on that cable is 115kbps.

  My preliminary testing of this setup on a prototype system have been less than stellar so far. I set up two PCs, each with serial ports, and hooked them together with a null modem. I then set the baud rates of the ports to 115kpbs and then attempted to stream a web cam video feed over the serial connection in real-time using ffmpeg. The results weren’t very encouraging, but I at least did manage to get some sort of image to show up.

  I guess I need to play around with the ffmpeg encoding options some more. But I need to ask : am I wasting my time with this idea, or should what I am asking here be possible ?
