bibliothèque de liens vidéos : mise à jour (C#/Vala)
janvier
2013
Un article de Rachel
voici une nouvelle version de ma bibliothèque de liens vidéo, mise à jour suite à la modification du code source de youtube. Le code est moche certes, mais il fonctionne. Manque juste la gestion de la qualité.
la version c# nécessite json.Net, disponible ici
Le code C# :
using System;
using System.IO;
using System.Collections;
using System.Collections.Generic;
using System.Net;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
namespace Media
{
public class Video

protected List<string> qualities;
protected Dictionary<string,string> table;
protected WebClient wc;
protected JObject o;
public Video(){
urls = new List<string>();
table = new Dictionary<string,string>();
qualities = new List<string>();
wc = new WebClient();
}
public Video (string url) : this()
{
o = JObject.Parse (wc.DownloadString (url));
}
public Video (string url, string param): this()
{
wc.DownloadFile (url, "temp");
StreamReader sr = new StreamReader ("temp");
string str;
while ((str = sr.ReadLine ())!=null) {
if(str.Contains (param)){
string[] tab = str.Split(new string[]{" = "},StringSplitOptions.None);
tab[1] = tab[1].Trim(';');
o = JObject.Parse (tab[1]);
break;
}
}
}
public List<string> Urls {
get{return urls;}
}
public Dictionary<string,string> Table {
get{return table;}
}
}
public class Dailymotion : Video
