    Le lecteur ne fonctionne pas sur Internet Explorer
    Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

  • avio : fix potential crashes when combining ffio_ensure_seekback + crc

    avio : fix potential crashes when combining ffio_ensure_seekback + crc

    Calling ffio_ensure_seekback() if ffio_init_checksum() has been called
    
on the same context can lead to out of bounds memory accesses and
    
crashes. The reason is that ffio_ensure_seekback() does not update
    
checksum_ptr after reallocating the buffer, resulting in a dangling
    
pointer.
    

    This effectively fixes potential crashes when opening mp3 files.

  • OpenCV ffmpeg issues when running Windows 10 app on Windows 7

    1er 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.

    • Did you encounter this type of issue and, maybe, have part of a solution ?
    • I would like to monitor which DLLs are loaded as the program runs and see possible "DLL not found" errors. Is it possible, especially on a machine that does not have the entire developement environment ?
    • Can building OpenCV on my own address the issue ?
    • Even further, would it be worth to port the development environment on Windows 7 and build from there ? This requires significant work due to the project itself.
