PermissionError: [WinError 5] Access is denied

• When I run youtube-dl.exe with c# process class on server, it returns below error in StandardOutput:

Traceback (most recent call last): File "__main__.py", line 19, in <module> File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\rg3\tmpc7h_sle1\build\youtube_dl\__init__.py", line 449, in main File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\rg3\tmpc7h_sle1\build\youtube_dl\__init__.py", line 416, in _real_main File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\rg3\tmpc7h_sle1\build\youtube_dl\YoutubeDL.py", line 367, in __init__ File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\rg3\tmpc7h_sle1\build\youtube_dl\YoutubeDL.py", line 2100, in _setup_opener File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\rg3\tmpc7h_sle1\build\youtube_dl\utils.py", line 642, in make_HTTPS_handler File "C:\Python\Python34\lib\ssl.py", line 439, in create_default_context File "C:\Python\Python34\lib\ssl.py", line 390, in load_default_certs File "C:\Python\Python34\lib\ssl.py", line 377, in _load_windows_store_certs PermissionError: [WinError 5] Access is denied

My Version is youtube-dl --version: 2016.0.31.0 and also when I used latest version,this problem was occured too.

• I've verified and I assure that I'm running youtube-dl 2016.0.31.0

What is these errors?I don't have these paths and files with these directories.
And Here is my code

string ydlPath = Server.MapPath("/ydlPath/youtube-dl.exe");
string tempLocation = Server.MapPath("/ydlPath/");

    System.IO.StreamReader errorreader;
    System.Diagnostics.Process proc = new System.Diagnostics.Process();
    proc.EnableRaisingEvents = false;
    proc.StartInfo.ErrorDialog = false;
    proc.StartInfo.RedirectStandardError = true;
    proc.StartInfo.FileName = ydlPath ;
    //proc.StartInfo.Arguments = "-F \"" + Url + "\"";
    proc.StartInfo.WorkingDirectory = tempLocation;
    proc.StartInfo.Arguments = "-f bestvideo[ext=mp4]+bestaudio[ext=m4a] \"" + Url + "\"";
    proc.StartInfo.Verb = "runas";
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.CreateNoWindow = false;
    proc.StartInfo.RedirectStandardOutput = true;
    proc.Start();
    errorreader = proc.StandardError;
    string Output = proc.StandardOutput.ReadToEnd();

    proc.WaitForExit();
    proc.Close();

My Description

I used this on my local and it works fine. Also when I use youtube-dl.exe with cmd on server or on my local I don't have problem.

Are you using IIS? It's a Python bug. Could you install Python 2.7.12 or 3.5.2 and use the zipped version of youtube-dl?

[parsasaei]

@yan12125 Yes,I'm using iis,and I installed python 3.4.0 in C:\Python\Python34\ Matching with error sayed.

[parsasaei]

@yan12125 How can I install this zipped version?

[yan12125]

Download that file, then

C:\PythonXY\python.exe C:\some\directory\youtube-dl

[parsasaei]

@yan12125 What should I type In cmd? I ask this question because when I use this in cmd, I can configure it on my server code.
I mean command code for dl is like ablout this:

C:\PythonXY\python.exe C:\some\directory\youtube-dl -f bestvideo[ext=mp4]+bestaudio[ext=m4a] **YoutubeVideoLink**

[yan12125]

Just replace the path to python.exe and youtube-dl to real paths. Anything wrong?

[parsasaei]

@yan12125 Thank you very much.It worked with your beneficial helps.
After install python 3.5 in c:\Python35
I use it in my code :

string ydlPath = @"C:\Python35\python.exe";
string ydl = @"C:\YoutubeDownload\ydlPath\youtube-dl";
string tempLocation = Server.MapPath("/ydlPath/");
        System.IO.StreamReader errorreader;
        System.Diagnostics.Process proc = new System.Diagnostics.Process();
        proc.EnableRaisingEvents = false;
        proc.StartInfo.ErrorDialog = false;
        proc.StartInfo.RedirectStandardError = true;
        proc.StartInfo.FileName = ydlPath ;
        //proc.StartInfo.Arguments = "-F \"" + Url + "\"";
        proc.StartInfo.WorkingDirectory = tempLocation;
        proc.StartInfo.Arguments = ydl + " -f bestvideo[ext=mp4]+bestaudio[ext=m4a] \"" + Url + "\"";
        proc.StartInfo.Verb = "runas";
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.CreateNoWindow = false;
        proc.StartInfo.RedirectStandardOutput = true;
        proc.Start();
        errorreader = proc.StandardError;
        string Output = proc.StandardOutput.ReadToEnd();

    proc.WaitForExit();
    proc.Close();

Thank You.

[yan12125]

Glad to see that fixed :)

@yan12125 With this compressed python version,I can't download from somelinks,but with exe version it's work.
How can I handle it? can I?
have this compressed python a new version for this isssue or I should do anything?

[yan12125]

@parsasaei Could you post the command line output of both versions?

[parsasaei]

@yan12125 yes. exe version download file and here exists output of it:

but python compressed output is empty and not return anything.
and here is this youtube link which I want to download it :https://www.youtube.com/watch?v=MZctQy6uEo8

[yan12125]

How did you run the compressed version?

[parsasaei]

With process class of c#

[yan12125]

Could you paste relevant C# codes?

[parsasaei]

In top of this topic it's there

[yan12125]

Nothing printed to StandardError either?

[parsasaei]

it's print:
ERROR: MZctQy6uEo8: YouTube said: This video is not available.

[yan12125]

For https://www.youtube.com/watch?v=MZctQy6uEo8, I got "This video is not available." here too. Does the exe version and the Python version run on the same PC?

[parsasaei]

No.It's different.I check exe version my local pc,and check python verion on server

[parsasaei]

On server, exe vesrion return YouTube said: This video is not available too.

[parsasaei]

What is the reason of it?is it related to location ip?

[yan12125]

Yes, and I guess you need a proxy on the server. From the youtube page, it says only the following countries are allowed to watch this video: AS,AU,BE,CA,DK,FI,FR,GB,GU,IE,IS,KR,LU,MP,MX,NL,NO,NZ,PR,SE,US,VI. Full names for those abbreviations can be found in http://data.okfn.org/data/core/country-list

[parsasaei]

My server location is on "United States, Illinois, Chicago", and with this recommendation,it must be download.

[yan12125]

Does your server allow running browsers? (IE, edge, etc.) If so could you open https://www.youtube.com/watch?v=MZctQy6uEo8 and check whether it plays or not?

[parsasaei]

It can't open on browser of server.

[parsasaei]

Sorry, my server location is on Netherlands but Netherlands exists in list of countries which can access to watch this video too.

[yan12125]

youtube-dl tries its best to mimic browsers. If you got "This video is not available" in youtube-dl, I bet you'll get the same in browsers. You may want to ask Google why blocking your server. AFAIK there are reports that geolocation detection misbehaves.

[parsasaei]

Thank you so much.
