Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

How to write a unit test class that creates a new process in C#
12 mars 2023, par IceAgeI have a question about how to write unit test method that creates a new process.


At the moment I write a normal unit test to create a process, but it's very difficult to setup.


This is my code I want to test.


using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;

namespace xxx
{
 public class FFmPeg
 {
 private Process _process;
 private string ffmpegPath { get; set; }
 private Regex _durationRegex;

 public event EventHandler<string> OutputData;
 public event EventHandler<int> ProgressChange;

 public FFmPeg()
 {
 _process = new Process();
 ffmpegPath = Path.Combine(Directory.GetCurrentDirectory(), "engine", "ffmpeg.exe");
 }

 public void Run(string Argument)
 {
 _process.StartInfo.FileName = ffmpegPath;
 _process.StartInfo.Arguments = $"{Argument} -y";
 _process.StartInfo.UseShellExecute = false;
 _process.StartInfo.RedirectStandardOutput = true;
 _process.StartInfo.RedirectStandardError = true;
 _process.StartInfo.StandardOutputEncoding = Encoding.UTF8;
 _process.StartInfo.CreateNoWindow = true;
 _process.OutputDataReceived +=(o,e) =>
 {
 };
 _process.ErrorDataReceived += (o, e) =>
 {
 if (string.IsNullOrEmpty(e.Data) == false)
 {
 OnProgressChange(OutputExtractor.GetProgress(e.Data));
 }//end if.check data is not empty
 };

 _process.Start();
 _process.BeginOutputReadLine();
 _process.BeginErrorReadLine();
 _process.WaitForExit();
 } //end method

 protected virtual void OnProgressChange(int progress)
 {
 ProgressChange?.Invoke(this,progress);
 } //end method

 protected virtual void OnOutputData(string data)
 {
 OutputData?.Invoke(this, data);
 }
 }
}
</int></string>

Thanks for any helpful answers, and sorry for my English.

Mp4 Video File not playing after downloading using Content Disposition php but it plays when it streams directly from the server
1er juin 2021, par Razor RasshI'm trying to combine a video and audio file using the FFMPEG and it worked successfully for me. The FFMPEG successfully created the MP4 file in the target destination folder. When I'm trying to download the Video file from the destination folder using Content-Disposition in Php. The server successfully downloads the Video file from the exact target folder.


The problem is that when I'm trying to play the video using VLC or any other player, nothing happened. The VLC player just launched and do nothing. I checked the downloaded file size with the video file located on the server and found that they both are the same size.


The code I used for creating Video file and content disposition is,



 $downloadFolderPath = "/var/www/html/temp/{$downloadFolderName}";
 $result = mkdir($downloadFolderPath, 0777); 
 $downloadFileName = "$downloadFolderPath/$filename";
 //echo $downloadFileName;
 $command = $ffmpeglocation." -i $audio_link -i $link -c:v copy -c:a aac -preset fast -crf 20 $downloadFileName 2>&1";
 shell_exec($command);

 $file=fopen($downloadFileName,'r');
 header("Content-Type:video/mp4");
 
 header("Content-Disposition: attachment; filename=$filename");
 
 header('Content-Description: File Transfer');
 header('Content-Type: application/octet-stream');
 
 header('Content-Disposition: attachment; filename="'.basename($downloadFileName).'"');
 header('Expires: 0');
 header('Cache-Control: must-revalidate');
 header('Pragma: public'); 
 header('Content-Length: ' . filesize($downloadFileName)); 
 flush(); // Flush system output buffer
 readfile($downloadFileName); 
 die();


The above code did its purpose by properly downloading the video file hosted on the server. But after downloading, the video file is not playing. I tried to access the file directly through the URL of the file in the browser and it plays fluently in the browser.


Help me out. Sorry for the bad english.
