• How to install ffmpeg on shared hosting ? [duplicate]

  19 mars 2021, par R.H. Tasin

  I am using shared hosting and installed a PHP script there. This script needs FFmpeg (recommended version 3.0+) to work. But I don't know how to install it on shared hosting. I have searched on youtube, they are showing, download the FFmpeg file from ffmpeg.org then set the path inside the script. but that's not working for me. FFmpeg needs to be installed on my server to make this script work.

  


  My server info :

  


  Hosting Package : undefined

  


  Server Name : server

  


  cPanel Version : 92.0 (build 6)

  


  Apache Version : 2.4.46

  


  PHP Version : 7.3.23

  


  MySQL Version : 5.7.33-cll-lve

  


  Architecture : x86_64

  


  Operating System : linux

  


  Shared IP Address : 161.97.101.164

  


  Path to Sendmail : /usr/sbin/sendmail

  


  Path to Perl : /usr/bin/perl

  


  Perl Version : 5.16.3

  


  Kernel Version : 3.10.0-1127.19.1.el7.x86_64

  


  I have tried to run some command VIA terminal of my hosting, but whatever command I type, it says that "command not found".


  


  so now tell me guys, how can I install FFmpeg on my server ?

• Concatenate multiple video files alongside delayed audio files

  28 mars 2022, par Spartan 117

  I am currently working on a utility that is responsible for pulling audio and video files from the cloud and merging them together via FFMPEG. As I am new to FFMPEG, I am going to split the question into an FFMPEG part and a C# part just so people can answer either 1 part or the other (or both !).

  


  FFMPEG Part

  


  Currently, I have a working FFMPEG arg if there is only 1 video file present and it needs to be merged with multiple files.

  


  ffmpeg -i input1.mkv -i input1.mka -i input2.mka -i input3.mka -i input4.mka -filter_complex "[1:a]adelay=0s:all=1[a1pad];[2:a]adelay=20s:all=1[a2pad];[3:a]adelay=30s:all=1[a3pad];[4:a]adelay=40s:all=1[a4pad];[a1pad][a2pad][a3pad][a4pad]amix=inputs=4:weights=1|1|1|1[aout]" -map [aout] -map 0:0 output4.mkv


  


  The delays you see in there are determined by subtracting the start time of each file from the start time of the earliest created audio or video file. I know that if I wanted to create a horizontal stack of multiple videos, i could just do

  


  ffmpeg -i input1.mkv -i input1.mka -i input2.mkv -i input2.mka -i input3.mka -i input4.mka
-filter_complex 
"[2:v]tpad=start_duration=120:color=black[vpad]; 
 [3:a]adelay=120000:all=1[a2pad]; 
 [4:a]adelay=180000:all=1[a3pad];
 [5:a]adelay=200000:all=1[a4pad]; 
 [0:v][vpad]hstack=inputs=2[vout]; 
 [1:a][a2pad][a3pad][a4pad]amix=inputs=4:weights=1|1|1|1[aout]" 
 -map [vout] -map [aout] 
 output.mkv


  


  but what I want to do is both keep those delays for the audio and video files AND concatenate (not stack) those videos, how would i go about doing that ?

  


  C# Part

  


  You see that giant arg up there ? The utility is supposed to generate that based on a List of recordings. Here is the model.

  


  List<filemodel> _records;&#xA;public class FileModel {&#xA;  public string Id { get; set; }&#xA;  public string FileType { get; set; }&#xA;  public string StartTime { get; set; }&#xA;}&#xA;</filemodel>

  


  The utility has to then go through that list and create the arg (as seen in the FFMPEG part) to be executed by the Xabe.FFMPEG package. The way i was thinking to approach this is to basically create 2 string builders. 1 string builder will be responsible for dealing with the inputs, the other string builder. Here is what i have so far

  


  private async Task CombineAsync()
    {
        var minTime = _records.Min(y => Convert.ToDateTime(y.StartTime));
        var frontBuilder = new StringBuilder("-y ");
        var middleBuilder = new StringBuilder("-filter_complex \"");
        var endString = $" -map [vout] -map [aout] {_folderPath}\\CombinedOutput.mkv";

        for (var i = 0; i < _records.Count; i++)
        {
            var type = _records[i].FileType.ToLower();
            var delay = (Convert.ToDateTime(_records[i].StartTime).Subtract(minTime)).TotalSeconds;
            frontBuilder.Append($"-i {_folderPath + "\\" + _records[i].Id} ");
            var addColon = i != _records.Count - 1 ? ";" : "";
            middleBuilder.Append(type.Equals("video") ? $"[{i}:v]tpad=start_duration={delay}:color=black[v{i}pad]{addColon} " : $"[{i}:a]adelay={delay}s:all=1[a{i}pad]{addColon} ");
        }
        middleBuilder.Append("\"");
        Console.WriteLine(frontBuilder.ToString() + middleBuilder.ToString() + endString);
        // var args = frontBuilder + middleBuilder + endString;
        // try
        // {
        //     var conversionResult = await FFmpeg.Conversions.New().Start(args);
        //     Console.WriteLine(JsonConvert.SerializeObject(conversionResult));
        // }
        // catch (Exception e)
        // {
        //     Console.WriteLine(e);
        // }
    }


  


  


  1. Is this the correct way to go about building the argument out ?

     


  


  2. How in god's name do i get something like this in there, since it relies on naming and total count for the piping and inputs=

     


       [0:v][vpad]hstack=inputs=2[vout]; // This part will change for video concatenation depending on what gets answered above
  [1:a][a2pad][a3pad][a4pad]amix=inputs=4:weights=1|1|1|1[aout]
