• How can I start ffmpeg while playing a full screen game ?

  11 janvier 2021, par Muhamed Shair benshair

  This is a class of the ffmpeg :

  


  using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using System.IO;  
using System.Diagnostics;  
  
namespace Ffmpeg_App  
{  
    class Ffmpeg  
    {  
        Process process;  
  
        public void Start(string FileName, int Framerate)  
        {  
            process = new System.Diagnostics.Process();  
            process.StartInfo.FileName = @"D:\ffmpegx86\ffmpeg.exe"; // Change the directory where ffmpeg.exe is.  
            process.EnableRaisingEvents = false;  
            process.StartInfo.WorkingDirectory = @"D:\ffmpegx86"; // The output directory  
            process.StartInfo.Arguments = @"-f gdigrab -framerate " + Framerate + " -i desktop -preset ultrafast -                                                                     pix_fmt yuv420p " + FileName;  
            process.Start();  
            process.StartInfo.UseShellExecute = false;  
            process.StartInfo.CreateNoWindow = false;  
            Close();  
        }  
  
        public void Close()  
        {  
            process.Close();  
        }  
    }  
}  


  


  And in form1 :

  


  At the top :

  


  Ffmpeg fmpeg = new Ffmpeg();


  


  In a button click event :
To start :

  


  private void Start_Click(object sender, EventArgs e)  
        {  
            fmpeg.Start("test.mp4", 24);  
        }


  


  and to stop :

  


  private void Stop_Click(object sender, EventArgs e)  
        {  
            fmpeg.Close();  
        }


  


  The problem is when I'm in full screen game I don't have access to the form and the buttons they are hidden in the background.

  


  I need to make some global keys hook maybe ?

  


• Couldn't find platform family in Info.plist for dylib CFBundleSupported platforms or Mach-O LC_VERSION_MIN

  1er décembre 2016, par user2331687

  

  I have developed a App (Mac OS) and I want release it to Mac App Store, and my App use the FFMPEG library, so there are many .dylib (as you can see, for example, libSDL-1.2.0.dylib), when I upload my App, and I got this error, I have googled several days, but I don’t know how to add the "platform family" to a .dylib, since the dylib is build from command line. Can anyone help me to solve this problem, thanks very much !

  avcodec/opus : always use ambisonic layout for mapping family 2
  No need to use a Custom layout when the non diegetic channels can be
  
  described as a standard mask.
