  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • installing yasm / nasm on heroku with vulcan

    21 novembre 2013, par scientiffic

    I'm trying to do a build of ffmpeg on Heroku, and I need to use libvpx. In order to install libvpx, I need to have nasm or yasm. I tried installing both using vulcan, but I keep getting the error Neither yasm not nasm has been found

    Here is what I did

    Installing Nasm

    Installing Yasm

    Installing Libvpx

    Attemping to build libvpx yields this error :

    Packaging local directory... /.rvm/gems/ruby-1.9.2-p320/gems/vulcan-0.8.2/lib/vulcan/cli.rb:49: warning: Insecure world writable dir /usr/local in PATH, mode 040777

Configuration failed. This could reflect a misconfiguration of your
    
toolchains, improper options selected, or another problem. If you
    
don't see any useful error messages above, the next step is to look
    
at the configure error log file (config.err) to determine what
    
configure was trying to do when it died.

    How can I successfully build libvpx on heroku using vulcan ?

    The instructions I've been (loosely) following are from here :

    https://gist.github.com/czivko/4392472

    And the reason I need to use libvpx is that I'm using the carrierwave-video gem in my Rails app to convert videos, and it needs libvpx to convert to webm to support video playback in Firefox.

  • {OpenAL(+FFmpeg)} How to queue variable size buffer due to ogg format ?

    11 février 2014, par user3293833

    (First of all, I may feel sorry about my poor English as it's not my native language.)

    I use FFmpeg to decode some audio file and play it with OpenAL by "stream"(i.e."queue" and "unqueue" function of OpenAL).

    When I use my program to play .ogg file, I find that it has a variable nb_samples.(due to ogg has variable bit rate ??) There are 128 B, 512 B and 1024 B of nb_samples. As a results, I must call alDeleteBuffers and alGenBuffers before I use alBufferSamplesSOFT(similar to alBufferData) because it would fail to call alBufferSamplesSOFT without recreate the buffer.
    Notes : alBufferSamplesSOFT is provided by OpenAL Soft. You can just see it as alBufferData.

    Nevertheless, I think it's foolish and inefficient if I do this. Is there is some smart method ? I paste the part of code :

    while (av_read_frame(...) == 0){
    
  avcodec_decode_audio4(...);
    
  swr_convert(...);  // to convert PCM format from FLTP to FLT
    
  alDeleteBuffers(1, theBuffers[?]);
    
  alGenBuffers(1, theBuffers[?]);
    
  alBufferSamplesSOFT(...);  // put those data into OpenAL buffer
    
}

    if I don't do this, It would failed to update the OpenAL buffer. Is there any method to create a variable size buffer or a big size buffer ? Or is there any method to change the size of buffer ?

    Thanks for you guys.
