How to download .ism files protected by DRM (Widevine or IIS Smoth Streaming)
16 septembre 2019, par Foopy7774I’m struggling to download a video which is protected by DRM or something else (idk)...I tried to download it by using VLC, ismdownloader, ffmpeg and youtube-dl but the video seems encrypted. There bound to be a way to do it, given that Chrome is able to read it...
I’ve seen that they are using Widevine or IIS Smooth Streaming, I don’t really know...but if you can’t answer my post, can you atleast set me on the right path by telling me :
What they use ? Widevine ? IIS Smooth Streaming ? Both ?Video link :

Place two videos side by side using ffmpeg ?and download it as one file
5 août 2019, par marceloo1223I have two video files, which I want to play side by side and download them later. I used FFMPEG to merge them as one :
protected void combinetwovideo()
{
string strParam;
string Path_FFMPEG = Path.Combine(HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings["FFMpegPath"]));
string apppath=HttpRuntime.AppDomainAppPath;
//Merging two videos
String video1=apppath+"\\recordings\\client2019-08-03 02_23_59";
String video2 =apppath+"\\userrecord\\User2019-08-03 02_24_00";
String strResult =apppath+"\\RESULT\\";
strParam = string.Format("-i ('" + video1 + "') -i ('" + video2 + "') -filter_complex \'[0:v]pad=iw*2:ih[int];[int][1:v]overlay=W/2:0[vid]' /-map [vid] -c:v libx264 -crf 23 -preset veryfast output.mp4");
process(Path_FFMPEG, strParam);
}public void process(string Path_FFMPEG, string strParam)
{
try
{
Process ffmpeg = new Process();
ProcessStartInfo ffmpeg_StartInfo = new ProcessStartInfo(Path_FFMPEG, strParam);
ffmpeg_StartInfo.UseShellExecute = false;
ffmpeg_StartInfo.RedirectStandardError = true;
ffmpeg_StartInfo.RedirectStandardOutput = true;
ffmpeg.StartInfo = ffmpeg_StartInfo;
ffmpeg_StartInfo.CreateNoWindow = true;
ffmpeg.EnableRaisingEvents = true;
ffmpeg.Start();
ffmpeg.WaitForExit();
ffmpeg.Close();
ffmpeg.Dispose();
ffmpeg = null;
}
catch (Exception ex)
{
}
}But this method outputs nothing and does not throw any errors. I’m confused about the
strParam
query. Did I write it wrong or am I missing something. Any help would be apreciated. -
Download youtube videos with youtube-dl/ffmpeg in php
24 juillet 2019, par Baraque ObahamasI have been using youtube-dl for a long time, and I now want to install it on my dedicated server to make it easier for me to download content.
I created a php script that allows me to download the video of my choice to the server, then I download it to my computer, pretty cool !
I am now trying to improve this script in order to redirect only the feed to avoid uploading the video to the server.
Example with this site : https://mpgun.com
It seems to redirect the stream without downloading the video to the server. If you try to download a video that lasts 3 hours, the site will offer you the download immediately !I think ffmpeg allows you to do that, only I don’t know where to start in the code.
Do you have any idea how to set this up in php ?
Thank you
