• Anomalie #3420 (Nouveau) : ajaxCallback.js + les styles de la balise p

  9 avril 2015, par chan kalan

  http://contrib.spip.net/prive/javascript/ajaxCallback.js
  génère une balise p juste avant la balise fermante /body
  cette balise est visible et crée une marge blanche en bas de page à cause de la règle css suivante :
  h1, h2, h3, h4, h5, h6, ul, ol, dl, p, blockquote
  padding : 10px ;
  

  Suppositions :
  - Il me semble que ce ne serait pas le cas si les styles top et left de cette balise p étaient déterminés :
  left :-5000px ;top :-5000px ;
  au lieu de ceci actuellement
  left :-5000 ;top :-5000 ;

  - Ou au moins prévenir l’héritage de certaines règles comme le padding en définissant padding:0 ;

  26 mai 2015, par MichaelMHerbert

  ffmpeg is not working. I put ffmpeg in site root folder. here is my function for converting videos. I also almost try each and every method and try many things on google, but I am unable to figure what is problem. I also try to install ffmpeg extension on my 64bit version system but I get another error as I start up xammp

  "Unable to load dynamic library ’D :\xamp\php\ext\php_ffmpeg.dll’ - %1 is not a valid Win32 application."

  I am working on localhost xammp and php version is 5.5.19

• gstreamer rtsp streaming chain with LGPL elements

  25 avril 2016, par user3612009

  The following chain seem to work well to stream video :

  gst-launch filesrc location=/home/manusha/Downloads/movies/<movie file="file">.mkv ! decodebin ! ffenc_mpeg4 bitrate=5000000 ! rtpmp4vpay mtu=1400 pt=96 ssrc=0 timestamp-offset=0 seqnum-offset=0 send-config=true ! udpsink host=127.0.0.1 port=5000
  
  </movie>

  This chain is able to receive the stream and play it :

  gst-launch udpsrc uri=udp://127.0.0.1:5000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP4V-ES, profile-level-id=(string)1, config=(string)000001b001000001b58913000001000000012000c48d88007d0a041e1463000001b24c61766335322e3132332e30, payload=(int)96, ssrc=(uint)298758266, clock-base=(uint)3097828288, seqnum-base=(uint)63478" ! rtpmp4vdepay ! ffdec_mpeg4 ! autovideosink

  My problem is, both ffdec_mpeg4 and ffenc_mpeg4 are GPL licensed and will not suit my purpose because I need to redistribute them. I am lookiing for advice on alternative stream chains that I can form only with LGPL licensed elements. The streaming to be used only inside a LAN, but it need to support HD quality streaming.
