• Setup FFMpegCore in Visual Studio 2019

  27 juillet 2022, par DsiakMondala

  I am confused on the basics of using a library. I understand that there is a library called FFMpeg and a wrapper called FFMpegCore so we can use FFMpeg with C#, correct ? I downloaded both FFMpeg and FFMpegCore and I have them in my project's folder. Although I didn't perceive any class named FFMpegOptions in either of the file's folders.
I am stuck on how to actually set it up so I can use it in my little project, I never downloaded someone's library before. Can somebody please walk me though the motions of connecting the three of them together ?

  


  So far I experimented with :

  


  

  • Add a reference to my project, but there doesn't seem to be any .dll, .tlb, .olb, .ocx or .exe files to add

  


  • Add an existing project to my solution. There is a project called FFMpegCore.csproj but adding it raises a missing SDK error. Weirdly enough, opening the same project as a standalone doesn't raise any issues which makes me thing the operation I am trying is inadequate.

  


  


  I am sure this is a silly and easy setup to perform but I just don't know enough to find a solution.

  


• Python script doesn't work properly when ran through terminal, but works fine in Jupyter and Visual Studio

  21 octobre 2018, par Ivan Novikov

  I have a script to extract the audio from all video files in a folder.

  The folder with videos is located at : /Users/MyName/Downloads/Video_Audio_files

  When I try to run it through terminal and I’m prompted for the folder path folder = input("Path to folder:"), I drag and drop it there (which is how I got the above path), but the script doesn’t seem to be working (stuck at 0 out of 7 and no output files).

  When I input exactly the same path when prompted in Jupyter Notebook or in Visual Studio it works perfectly !

  Edit : I think I have found the issue, when I drag and drop the folder, there is an extra space (’Downloads/folder ’ instead of ’Downloads/folder’).

  pbar = ProgressBar()
  
  files = []
  
  extensions = []
  
  folder = input("Path to folder:")
  
  #folder = 'Video_Audio_files'
  
  pathlist = Path(folder).glob('**/*.mp4')
  
  for path in pathlist:
  
      path_in_str = str(path)
  
      name = path_in_str.split("/")[1]
  
      files.append(path_in_str.split(".")[0])
  
      extensions.append(path_in_str.split(".")[1])
  
  
  
  os.system('cd ' + folder)
  
  
  
  for i in pbar(range(len(files))):
  
      video_format = extensions[i]
  
      video_name = files[i]
  
      output_format = 'flac'
  
      output_name = video_name + '_audio'
  
  
  
      bashCommand = 'ffmpeg -i ' + video_name + '.'   + video_format + ' -f ' + output_format + ' -ab 192000 -vn ' + output_name + '.' + output_format
  
  #should be of this format: bashCommand = 'ffmpeg -i Video.mp4 -f flac -ab 192000 -vn ExtractedAudio.flac'
  
  
  
      os.system(bashCommand)

• How to add dagger in my android studio project

  14 janvier 2016, par Vijay

  I am trying to compress the video using ffmpeg in android. I found one good example and I downloaded the project from https://github.com/WritingMinds/ffmpeg-android-java. It’s working fine. When I try to add that ffmpeg library in my project I am facing error. After make many changes I resolved many issues. But I can not clear the following issue :

  Error:(34, 13) Failed to resolve: com.squareup.dagger:dagger-compiler:1.2.2
  
  
  
  Error:(35, 13) Failed to resolve: com.squareup.dagger:dagger:1.2.2

  I decided to download the dagger.jar and dagger-compiler.jar. I download the jar and I added into my project. But I am facing another error.

  Error:Execution failed for task ':ContainerCentralen:compileDebugJava'.
  
  > java.lang.NoClassDefFoundError: javax/inject/Scope

  I can not solve this two issues. Please let me any idea to resolve this issue.
