  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • How to run a python code via Django templates ?

    18 novembre 2018, par Iskender Berdiev

    I want to execute code below when the is submitted (project on Django) :

    from os import system, listdir, remove
    
link = 'https://www.youtube.com/watch?v=ME9yO1KEVoo'
    

    
def download(): ## Downloading a video from YouTube using youtube-dl
    
    system("youtube-dl -o download {}".format(link))
    

    
def convert():  ## Converting downloaded video to mp3 format via ffmpeg.exe(same directory)
    
    listOfFiles = listdir('.')
    
    for i in listOfFiles:
    
        if i.startswith("download"):
    
            name = i
    
            system("ffmpeg -i {} download.mp3".format(name))
    

    
def main():
    
    download()
    
    convert()
    

    
main()

    I have tried to put this code into views.py :

    class download(TemplateView):

  • FFmpeg adding 0.05 seconds of silence to transcoded AAC file ?

    29 octobre 2015, par FTLRalph

    In Java, I’m using FFmpeg to convert a WAV file to AAC with the function :

    -i input.wav -ac 1 -ab 64000 -ar 22050 output.aac

    When I open these two files in Audacity, I can clearly see that the AAC file is 0.05 seconds longer, with 0.05 seconds of silence added to the beginning.

    This is an issue when I try to mux this AAC file with a video file - the audio doesn’t sync up.

    Is there some sort of parameter to prevent this behavior or another way to get around this issue ?

    Edit - Console output while running the function :

  • 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 :

    &#xA;

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

    &#xA;

    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 :

    &#xA;

    Adapter 0&#xA;  Description: Intel(R) HD Graphics 630&#xA;  Vendor ID:   0x8086&#xA;  Device ID:   0x5912&#xA;  SubSys ID:   0x86941043&#xA;  Revision:    4&#xA;  Luid:    46459&#xA;  Flags:    None&#xA;  Dedicated Video Memory:    128 MB&#xA;  Dedicated System Memory:  0 MB&#xA;  Shared System Memory:     8092 MB&#xA;Adapter 1 // &lt;- additional addapter&#xA;  Description: Intel(R) HD Graphics 630 &#xA;  Vendor ID:   0x8086&#xA;  Device ID:   0x5912&#xA;  SubSys ID:   0x86941043&#xA;  Revision:    4&#xA;  Luid:    1322913970&#xA;  Flags:    None&#xA;  Dedicated Video Memory:    128 MB&#xA;  Dedicated System Memory:  0 MB&#xA;  Shared System Memory:     8092 MB&#xA;Adapter 2&#xA;  Description: Microsoft Basic Render Driver&#xA;  Vendor ID:   0x1414&#xA;  Device ID:   0x8C&#xA;  SubSys ID:   0x0&#xA;  Revision:    0&#xA;  Luid:    50158&#xA;  Flags:    Software&#xA;  Dedicated Video Memory:    0 MB&#xA;  Dedicated System Memory:  0 MB&#xA;  Shared System Memory:     8092 MB&#xA;

    &#xA;

    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.

    &#xA;

    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 ?
