![]() An “FFmpeg” folder in its source package must contain the “ffmpeg.exe” and “ffplay.exe” files to work with the software. You can also explore additional creation parameters like codecs, frame size, frame rate, blur/sharpen amount, bitrate, add and modify subtitles, edit metadata, sampling frequency, and more. The UI of this program offers a variety of choices for use with the video file you wish to convert. Using the predefined Avanti/AviSynth pre-processor options does not require any prior knowledge of AviSynth.Īvanti doesn’t need to be installed because it is a portable application in a zip folder. It provides easy access to all FFmpeg options, including advanced ones. I have tried to trace using WinApiOverride32, with no results.Avanti is a free front-end for FFmpeg that allows you to add AviSynth as a pre-processor. ![]() 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.It seems that the DLL is simply not recognized on Windows 7.Įdit: Further investigation using Process Explorer clearly shows that the aforementioned DLL is not loaded when the app runs on Windows 7. 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. the isOpened call on VideoCapture returns false. The same video files that successfully load during the previous tests are not recognized by the app at all i.e. I have tested on a Windows 8 machine as well, no issues so far. On a Windows 10 computer, not the same as the developement machine and no developer libraries present, the video decoding works fine. Issues arise when I try to run the application in a standalone fashion with all the required DLLs in the same folder as the. Here, everything runs fine, I am able to decode a video using VideoCapture::open(). ![]() OpenCV version is 3.0, the official distribution. The development environment is on Windows 10, using QT Creator and MSVC12 64-bit as compiler. As far as I understood, the decoding part of OpenCV is delegated to ffmpeg in a separate DLL for licensing reasons. I need to maintain a desktop app written in C++, using Qt and OpenCV for some video processing. ![]()
