• How to run a bat file when clicking a button in an electron + react application ?

  12 novembre 2020, par Артем

  I am using Windows 7
  
I want to write a windows app using electron + react.
  
The essence of the application is to run bat files.
  
Bat files will execute their script.
  
In this case, I have already written baht files, they work with the FFMPEG.
  
I like FFMPEG and I would like to make it easy to use on Windows with such an application.
  
At this stage, I have two folders Your_files and Result, next to these folders are ready-made baht files and ffmpeg.exe.
  

  


  

  1. In the folder Your_files I put the files to convert.
     

  


  2. I click on the desired baht file, it converts.
     

  


  3. I take the finished files from the Result folder.
     

  


  


  I would like to write a nice application now.
  
There will be one window with buttons in the CMD style - minimalism. On the buttons, the labels are similar (mp4 - mkv) and others.
  
I also plan to place two folders Your_files and Result next to the application.
  
The principle is the same, only here is a beautiful visual interface with buttons for the place of many baht files.
  
It will be easier to visually choose what you need.
  
The crux of the question : How to launch a baht file when you click on a button in the application ?
  Perhaps you have some ideas on how to implement this even better .. I welcome your suggestions with a detailed description.
  
------------------------
  
P.S. I originally planned the following... But I decided to abandon this implementation. ))
  
I recorded a cycle in a baht file.
  
The cycle was launched in the bat file mshta.exe with HTML layout (visual interface). lol
  
Received the value of a variable, which he entered in the visual interface of the mshta.exe window.
  
The variable returned to the loop and the baht file was executed.
  
But I don't think this is the best approach. Use a similar hybrid.
  
Take a look at this for fun.

• Why ffmpeg can play h264 even when flag —disable-libx264 is set ? [closed]

  2 décembre 2020, par Jams

  To be complient with x264 licensing (for a commercial software I'm making) I plan to use a compiled version of ffmpeg without x264 support.
Here is the ouput of the command line ffmpeg -L :

  But when I play a video encoded with h264 it plays perfectly.
Is expected ? How to be sure I'm not infringing the license ?

  


  Here is where I downloaded the binaries :
https://github.com/BtbN/FFmpeg-Builds/releases
  
And I picked a release with the following name : win64-gpl-shared-4.3.zip

  


  Thanks.
