• FFMPEG "Could not allocate memory" Errors through php

  10 décembre 2019, par Applepiee

  I’ve tried to find a solution online for days now but cannot find any solution.

  I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.

  All commands that the script executes (copied from log files) were tried in shell and executed with no problems.

  The errors look like this :

• In the using directive "using Accord.Video.FFMPEG", FFMPEG does not exist in the name space

  15 septembre 2019, par StewartMetcalfe

  I am building an Azure Function in Visual Studio to convert a videos frames to images. I’m using the VideoFileReader class from Accord.Video.FFMPEG class. The code works on my machine but when trying to build this as an Azure Function Project, the using directive Accord.Video.FFMPEG errors.
  And subsequently the type VideoFileReader can not be found.

  I have tried re-installing the Accord, Accord.Video and Accord.Video.FFMPEG NuGet packages.

  using System.IO;
  
  using Microsoft.Azure.WebJobs;
  
  using Microsoft.Extensions.Logging;
  
  using Accord;
  
  using Accord.Video;
  
  using Accord.Video.FFMPEG;
  
  
  
  namespace ConvertVideo
  
  {
  
      public static class Function1
  
      {
  
          [FunctionName("Function1")]
  
          public static void Run([BlobTrigger("videos/{name}", Connection = "AzureWebJobsStorage")]Stream myBlob, string name, ILogger log)
  
          {
  
              log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
  
  
  
              //start a new videoFileReader
  
              using (var vFReader = new VideoFileReader())
  
              {
  
                  //open the video
  
                  vFReader.Open(name);
  
                  //get the framerate
  
                  double frameRate = vFReader.FrameRate.ToDouble();
  
                  //more code which converts a frame to jpg
  
              }
  
          }   
  
      }
  
   }

• Is there any way to input command into running "cmd" that we called before ? FFMPEG

  26 août 2019, par Rio Manik

  So, i tried to build some apps that can record my computer’s screen (i’m using ffmpeg).
  To record my screen i need to input some arguments into cmd, so i made a button that will run cmd and arguments on it when clicked, but here is the problem :
  the record process need to be stopped by pressing "q" or "ctrl+c",
  is that possible to input some extra command on running cmd ?
  because while recording my screen, i don’t want to see the cmd panel, because the app will do something and i need to record it, so i hide it, when the process that i need to record is completed i need to stop the record process through pressing one single button,
  is this possible ?

          Process cmd = new Process();
  
          cmd.StartInfo.FileName = "cmd.exe";
  
          cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
          cmd.StartInfo.Arguments = command;
  
          cmd.Start();
  
          cmd.WaitForExit();

  thanks !
