  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • ffmpeg fails to capture video running on screen

    21 septembre 2014, par Ralf

    I’m trying to capture a slide presentation as video. I’m using the following command to capture my screen

    ffmpeg \
    
   -f x11grab -s 1024x768 -r 25 -i $DISPLAY \
    
   -f alsa -i pulse \
    
   -vcodec libx264 -preset ultrafast -vb 1000k \
    
   -acodec libmp3lame -ab 128k \
    
   test.avi

    This works (application windows on the screen are visible and sound is recorded in test.avi), but the problem is : Any video shown on the screen (e.g. a youtube video running in a browser window, but also e.g. a video played by mplayer) only appears as an empty (e.g. green) box when I play the captured video (test.avi).

    I’m using ffmpeg version 0.8.16-4:0.8.16-0ubuntu0.12.04.1 on Ubuntu 12.04.5 LTS with the nvidia-331 driver (effect is the same with older nvidia-304).

    I would really appreciate any suggestions, thanks a lot !

  • How to distinguish a physical D3D adapter from a virtual adapter used by the Remote Desktop Protocol ?

    31 octobre 2023, par rustak

    I'm currently developing a desktop application(c#/wpf) that decodes video using FFmpeg. I would like to give the user the option to select an adapter for video decoding. I'm using Direct3D method EnumAdapters to list available adapters on current device which works fine. The list of available adapters looks something like this :

    


    Adapter 0
  Description: Intel(R) HD Graphics 630
  Vendor ID:   0x8086
  Device ID:   0x5912
  SubSys ID:   0x86941043
  Revision:    4
  Luid:    46459
  Flags:    None
  Dedicated Video Memory:    128 MB
  Dedicated System Memory:  0 MB
  Shared System Memory:     8092 MB
Adapter 2
  Description: Microsoft Basic Render Driver
  Vendor ID:   0x1414
  Device ID:   0x8C
  SubSys ID:   0x0
  Revision:    0
  Luid:    50158
  Flags:    Software
  Dedicated Video Memory:    0 MB
  Dedicated System Memory:  0 MB
  Shared System Memory:     8092 MB


    


    I have noticed that an additional adapter appears in the list of available adapters when RDP is used. The additional adapter has the same properties as the physical one ; the only difference is in the LUID. The output looks something like this :

    


    Adapter 0
  Description: Intel(R) HD Graphics 630
  Vendor ID:   0x8086
  Device ID:   0x5912
  SubSys ID:   0x86941043
  Revision:    4
  Luid:    46459
  Flags:    None

  Dedicated System Memory:  0 MB
  Shared System Memory:     8092 MB
Adapter 1 // <- additional addapter
  Description: Intel(R) HD Graphics 630 
  Vendor ID:   0x8086
  Device ID:   0x5912

  Luid:    1322913970

  Dedicated System Memory:  0 MB
  Shared System Memory:     8092 MB
Adapter 2
  Description: Microsoft Basic Render Driver
  Vendor ID:   0x1414
  Device ID:   0x8C
  SubSys ID:   0x0
  Revision:    0
  Luid:    50158
  Flags:    Software
  Dedicated Video Memory:    0 MB
  Dedicated System Memory:  0 MB
  Shared System Memory:     8092 MB


    


    I'm aware that the additional adapter is some kind of virtual adapter used by RDP. I have tried both of them, and it seems that both are suitable for video decoding using FFmpeg.

    


    However, from a UX perspective, it doesn't look or feel right that the combo box contains two adapters with the same name. So my question is : how can I distinguish a physical adapter from a virtual adapter used by the Remote Desktop Protocol ?

    vulkan : set VkDescriptorAddressInfoEXT.sType

    This was not done, resulting in validation issues, and potential
    
driver issues.
