  • Other interesting software

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • trying to make OpenCV 3.2.0 work with virtualenv

    24 juillet 2017, par lollercoaster

    I’m on Ubuntu 16.04 with Python 2.7 and virtualenv & virtualenvwrapper.

    By following this guide I managed to get the following script working with my system Python2.7 which has cv2 globally installed.

    I used this script to install it :

    The following script below works great with that system-wide installation :

    import cv2
    

    
img = cv2.imread('some_img.jpg')

    Though this one doesn’t - even the system Python can’t read videos for some reason...

    import cv2
    

    
video_capture = cv2.VideoCapture(0)
    
ret, frame = video_capture.read()
    
print ret  # always False

    but I want it to work with my virtualenv. So I recompiled OpenCV with :

    cmake -D WITH_QT=ON \
    
    -D WITH_OPENGL=ON \
    
    -D FORCE_VTK=ON \
    
    -D WITH_TBB=ON \
    
    -D WITH_GDAL=ON \
    
    -D WITH_XINE=ON \
    
    -D BUILD_EXAMPLES=ON \
    
    -D INSTALL_PYTHON_EXAMPLES=ON \
    
    -D ENABLE_PRECOMPILED_HEADERS=OFF \
    
    -D BUILD_NEW_PYTHON_SUPPORT=ON \
    
    -D OPENCV_EXTRA_MODULES_PATH=/home/me/code/myproject/opencv_contrib-3.2.0/modules \
    
    -D PYTHON_EXECUTABLE=~/.envs/myenv/bin/python \
    
    ..
    

    
make -j4
    
sudo make install
    
sudo ldconfig

    Unfortunately, while this works and I can import cv2 in the shell, it cannot read video using the above script, probably due to incorrect compilation or linking of ffmpeg ? The confusing part is the system-wide installation of OpenCV works fine, even without ffmpeg installed !

    What am I doing wrong ? How can I get OpenCV working with a virtualenv ?

    EDIT : Running the C++ video writing example has this result :

    $ cd /home/me/code/myproject/OpenCV-3.2.0/build/bin

  • ClickOnce Deployment looking for manifest signature on an nuget sourced .exe (FFMPEG #) as if it is a .csproj output. Deployment fails

    9 octobre 2019, par M_Ryce

    I have a C# forms app which utilizes the nuget package "FFMPEG Sharp" (Nuget Github) to generate video from a sequence of images.

    Unlike most nuget packages which simply pull in a .dll, installing FFMPEG Sharp places an "FFMPEG" folder into the .csproj root directory, in addition to bringing the appropriate .dll into "packages"

    Inside this folder are a few FFMPEG artifacts and a /bin folder containing FFMPEG executables. According to the project’s Github readme, this /bin directory needs to be specified in the app.config.

    From Github Readme example :

    <appsettings>
    
  <add key="ffmpegRoot" value="C:\ffmpeg\bin\"></add>
    
</appsettings>`

    Adjusting the above to work in alignment with the default location Nuget placed the dependency artifacts :

    <appsettings>
    
  <add key="ffmpegRoot" value="..\..\FFMPEG\bin"></add>
    
</appsettings>`

    Everything related to this dev effort has been smooth sailing, until I tried to utilize the existing Clickonce deployment for the app. The FFMPEG folder in my .csproj root wasn’t making it to the build output and therefore the application’s call to the FFMPEG .exe was throwing a null reference error. Understandable result, given that I had not set up any method of ensuring the FFMPEG artifacts made it to the build output with the same folder structure as existed on my local dev box.

    To counter this, I set a POST-build command to XCOPY....

    XCOPY "$(SolutionDir)MyApp\FFMPEG" "$(TargetDir)FFMPEG" /S /Y /I

    ...the nuget-provisioned FFMPEG artifacts into the build output root, and adjusted the config setting accordingly (see below)

    <appsettings>
    
  <add key="ffmpegRoot" value=".\FFMPEG\bin"></add>
    
</appsettings>`

    This worked like a dream when building/running locally. The XCOPY succeeded in placing FFMPEG folder contents into the compiled solution’s Debug/Release bin and the updated config referenced them. No errors.

    Attempting to deploy with the .NET ClickOnce tool has created a rather befuddling error though.

    (Apologies for formatting ugliness below. I tried but didn’t succeed. The important parts are in bold)

    ERROR SUMMARY
    Below is a summary of the errors, details of these errors are listed later in the log.

    ...

    My interpretation of this is that the ClickOnce deployment is treating the Nuget-sourced .exe’s as if they are compiled code from this very project, and checking for a signed manifest.

    This ClickOnce deployment was not set up by me, and had not needed to account for such external artifacts existing in the output previously. I do not believe turning off signed assemblies is an option for me, for security reasons.

    Is there a way to make ClickOnce deployments ignore a specific .exe when checking for signed manifests ? I think the "correct" intended usage is for FFMPEG to be pre-installed on the machine as a stand-alone application, but This is not an option for me at this time. I will need FFMPEG to be brought in by the ClickOnce.
