  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • OpenCV ffmpeg DLL not loaded when running app on Windows 7, works on 8 and 10

    2 novembre 2016, par David G.

    I need to maintain a desktop app written in C++, using Qt and OpenCV for some video processing. As far as I understood, the decoding part of OpenCV is delegated to ffmpeg in a separate DLL for licensing reasons.

    The development environment is on Windows 10, using QT Creator and MSVC12 64-bit as compiler. OpenCV version is 3.0, the official distribution. Here, everything runs fine, I am able to decode a video using VideoCapture::open().

    Issues arise when I try to run the application in a standalone fashion with all the required DLLs in the same folder as the .exe file. All cases below are 64-bit OSes.

    On a Windows 10 computer, not the same as the developement machine and no developer libraries present, the video decoding works fine. I have tested on a Windows 8 machine as well, no issues so far.

    On Windows 7, the things get tricky. The same video files that successfully load during the previous tests are not recognized by the app at all i.e. the isOpened call on VideoCapture returns false. For further testing, I stripped the opencv_ffmpeg300_64.dll file to narrow down the issue on Windows 10 and 8 ; as expected, without this DLL the app is no more able to open the same video files.

    It seems that the DLL is simply not recognized on Windows 7.

    Edit : Further investigation using Process Explorer clearly shows that the aforementioned DLL is not loaded when the app runs on Windows 7.

    • Is there something specific about how Windows 7 manages the DLL path resolution and eventual security measures ? Seems normal that the first search location is the same folder as the executable, which is the case here.

    I have tried to trace using WinApiOverride32, with no results.

  • Get a thumb from a partial loaded file [closed]

    6 novembre 2024, par JD11

    I use ffmpegwasm to get thumbnail of video files. Some time files are very large. Can i download only a part of file (using html header range) and get a thumbnail.

    


    i use this command for extraction :

    


    ffmpegWasm!.run(['-y','-ss','00:00:01','-i','temp.mp4','-vframes','1',"-an","-vf",
    "scale=$width:-1",outName
  ]);


    


    thank you in advance
