• Linphone Android Import and Build

  29 novembre 2013, par AppleDroid

  I am working on Linphone Library and using GITHUB repo and downloaded the zip file with Download Zip button.

  

  Now when i go through the README file i saw that i need to run ./prepare_sources.sh script then i ran it on terminal but it asks for file to patch as

  Now when i opened the folder inside submodules/externals/ffmpeg — It's completely empty
  and other folders are also empty.
  But on GitHub also i saw it with some kind of black folder which i can't select.
  I am stuck here ? should i do how can i get all these files into my directory so that i can make the build.

  One more thing Should i import this downloaded Zip into my eclipse it shows me these projects which one should i import (Should i import it after i download the Zip from Github or should i import it after running all the scripts to make the build on terminal and then import it in eclipse) ?

  Need Help .
  

  

• VideoWriter can't generate .avi file in C [closed]

  7 décembre 2022, par JohnChin

  I encounter the problem as the title now. The purpose of my code is using lots of images to generate a video. Here is my code :

  


  Mat frame = imread(img_path[0], -1) ;

  


  int codec = VideoWriter::fourcc('M', 'J', 'P', 'G');
double fps = 30.0;
Size sizeFrame(frame.cols, frame.rows);

VideoWriter OutputVideo(output_video, codec, fps, sizeFrame, TRUE);

int i = 0;
while (i != flag_img) {
    frame = imread(img_path[i], -1);
    resize(frame, frame, Size(frame.cols, frame.rows));
    OutputVideo.write(frame);
    i++;
}
OutputVideo.release();
destroyAllWindows();


  


  PS : img_path is the directory of images (ex : ../database/RushPixar/random/001.png)

  


  After running, there's no .avi file in my folder. Then I see the terminal, it displays there are lots of .dll files I lost and some .dll files I unloaded.

  


  list of .dll files of loading failed :

  


  

  • opencv_videoio_ffmpeg460_64d.dll

  


  • opencv_videoio_gstreamer460_64d.dll

  


  • opencv_videoio_intel_mfx460_64d.dll

  


  • opencv_highgui_gtk460_64.dll

  


  • opencv_highgui_gtk3460_64.dll

  


  • opencv_highgui_gtk2460_64.dll

  


  


  list of .dll files of unloading :

  


  

  • opencv_videoio_msmf460_64d.dll

  


  • opencv_videoio_ffmpeg460_64.dll

• creating Homebrew symlink for beginners

  19 mars 2021, par Platypore

  I am having issues installing the Rust dependency while trying to install ffmpeg through Homebrew on macOS 10.3.6. Terminal just eventually hangs, as is well known in other posts about the topic for Sierra (and I guess High Sierra too). I have installed Rust subsequently using the following command from their website :

  


  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh


  


  It seems I need to now create a symlink between the Rust directory created by the above command and Homebrew so that Homebrew can recognize the dependency as being installed, but I am absolutely not versed in how to do this ; my terminal knowledge is limited to very simple basics and plugging in code from other answers has not worked. I don't have the knowledge to discern what is a generic path meant to be replaced by specific locations and what is meant to be left as is when it comes to terminology such as prefix and $PATH.

  


  I believe the following are the paths I need to symlink to continue on with my installation of ffmpeg, but I honestly have no idea.

  


  /Users/usr/.rustup/toolchains/stable-x86_64-apple-darwin/bin/rustc 
/Users/usr/.rustup/toolchains/stable-x86_64-apple-darwin/bin/cargo


  


  Could anyone please help and explain step-by-step how to go about doing this ?
