• Using FFmpeg with Nvidia GPU acceleration

  27 janvier 2021, par derekc23

  I’m using Using FFmpeg with NVIDIA GPU Hardware Acceleration : : NVIDIA Video Codec SDK Documentation for Windows 10

  


  All goes well until I hit the last three commands :

  


  • Goto nv-codec-headers directory and install ffnvcodec

  


  make install PREFIX=/usr

  


  • Go to the FFmpeg installation folder and run the following command.

  


  ./configure —enable-nonfree –disable-shared —enable-cuda-sdk —enable-libnpp –-toolchain=msvc —extra-cflags=-I../nv_sdk —extra-ldflags=-libpath :../nv_sdk

  


  • Compile the code by executing the following command.

  


  make -j 8

  


  I cannot get the ‘make’ command to work – I get 'make' is not recognized as an internal or external command,
operable program or batch file.
I did try the next command, the ./configure one, this was also rejected.

  


  The documentation is : https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/

  


  Can anyone please help with this ?

  


• Java IO Streaming Large Files Video/Data/Sound [on hold]

  2 mars 2015, par James Relic

  I have a series of questions listed below regarding java.io streaming and sockets.

  1. What is a video streaming server ? How does it differ from a standard web server.

  2. Remember Napster/Morpheus etc ? They’re P2P programs, did they allow users to stream data to each other ? Is there a difference between streaming and downloading (on the clients end) ?

  3. How would you go about writing a generic program in java that streams anything to the client , word docs, mp3 files, videos files ? Would you use serverlets for this purpose ?

  4. If all you are doing is sending files video/sound/docs/text etc from one computer to another would you need to use specialist APIs like FFMPEG-Java, Red5 ?

  5. if you are sending video or sound as a file supposedly you don’t need to worry about encoding or decoding ?

  6. Do I need to worry about RTSP if im streaming videos as a file ? Rather then wanting them to play live on the client end ?

  I understand my questions sound very untechnical and basic, but I’m a little confused on this whole streaming topic and want to know the best way to stream large files of all types using the Java EE/Spring platform.

• Evolution #4610 (Nouveau) : HTML5 : name est déprécié pour une ancre

  30 novembre 2020

  Bonjour,

  https://developer.mozilla.org/fr/docs/Web/HTML/Element/a indique que :
  name HTML 4 seulement, Obsolète depuis HTML5
  Cet attribut est utilisé pour définir une ancre cible au sein de la page. La valeur de name est similaire à la valeur de l’attribut global id, et doit être un identifiant alphanumérique unique au document. Sous la spécification HTML 4.01, id et name peuvent être tous les deux utilisés sur un élément s’ils ont des valeurs identiques.

  Or, SPIP génère des ancres avec un a et un id identique.

  Résolution : ne générer que le id.

  Où ? Dans inc/filtres.php, ligne 2773 (en 3.3)

  Remplacer :
  $bloc_ancre = $ancres[$ancre] = "<a></a>";
  Par :
  $bloc_ancre = $ancres[$ancre] = "";
