same problem, may be youtube change their website source code again

[Vinquer]

Same issue here, since the end of November approximately (just to raise the number of persons concerned).
No error returned but impossible to get a working url on some videos using "YouTube.GetVideoUriAsync" (Vevo mainly)

[RicoSuter]

Can you post some video IDs?

[Vinquer]

Sure.
Not working VEVO : https://www.youtube.com/watch?v=oeCihv9A3ac
Not working, not VEVO : https://www.youtube.com/watch?v=6Yl9tgkEbTg

Working: https://www.youtube.com/watch?v=SuBDt7GCbIc

[mjdavy]

Looks like YouTube.GetVideoUriAsync is returning an invalid Uri for some videos, including everything I tried from vevo. Check out this playlist for testing https://www.youtube.com/playlist?list=PLtZ7tJkCfjGyPcROkcYAKdeIDXC3aZ9Uw

Numbers 1,9 and 38 work for me. the others do not. They were all working right before Christmas

[rajeshkomatlapalli]

Some Videos from Youtube Viveo are not playing using the MyToolkit.Multimedia.YouTube.GetVideoUriAsync(YoutubeID,MyToolkit.Multimedia.YouTubeQuality.Quality480P);

I installed MyToolkit & MyToolKit.Extended from Nuget Pckg Mgr. and i used this for playing videos from youtube on my Windows 8.1 Universal app and Windows 10 Universal app

For Exp: this url worked before 25th Dec "https://www.youtube.com/watch?v=D4sTViBfjVE" (Not VEVO ID) ,but the same url is not working today..

Some urls from youtube are working fine,
Any modifications in the code to be done, please help.

[mjdavy]

A little more info. Since Christmas, I'm getting http status code "Forbidden" on vevo videos using the Uri returned from GetVideoUriAsync. For example this vevo video id "fRh_vgS2dFE" generates a Uri that results in "Forbidden", but video id "RqQGUJK7Na4" (not vevo) returns success.

I am having this problem too with all the Youtube links that I try. Using Mytoolkit 2.5.8. Loading the video to a .Net MediaElement.

This is a link to a video. It has always worked in the past with no problems. Last tested in December.

This is the link returned by Mytoolkit.

error message from the .Net MediaElement is not very helpful.
Void OpenMedia(System.Uri)... Object reference not set to an instance of an object.... ... at System.Windows.Media.MediaPlayerState.OpenMedia(Uri source)

PS. Thanks for the Mytoolkit libraries. Awesome work.

I ended up switching to a modified version of YouTube Extractor. I ported it to work with Universal Windows Apps and added async support. I have not yet had time to submit a pull request to the owner, but meanwhile if you want to go this route and use my mods, you can find them here: https://github.com/mjdavy/TopTastic.net/tree/master/TopTastic in the YouTubeExtractor folder. All videos now work for me.

[Breakthru001]

@mjdavy ,
Thanks for that link. I'll take a look.

[Englbach]

I'm having this problem too. Please fix it

[wisien92]

Up - same problem

[RicoSuter]

I just used the same YouTubeExtractor code to fix the lib, check out v2.5.10 or directly use YouTubeExtractor. Thx @mjdavy
Just try again v2.5.10 and report if a video is still not working..

[Breakthru001]

The v2.5.10 fix did not work for me. Did anyone else try it ? Please let us know if it works for you or not.

[RicoSuter]

What youtube IDs have you tested with?

[Breakthru001]

This on always used to work. But not with v2.5.10 fix .

[Englbach]

Cound not play video on vevo.

[RicoSuter]

@SmokinLeather works for me in Switzerland. In what country are you trying to play the video?

[Breakthru001]

@RSuter , I'm in the United States. Hmm. Maybe it's my app. I'll do some more testing to see what Mtoolkit is returning for a video link. Thanks.

[RicoSuter]

The simplest way is to download the sources and run these unit tests:

https://github.com/MyToolkit/MyToolkit/blob/master/src/MyToolkit.Tests.WinRT/Multimedia/YouTubeTests.cs

[Breakthru001]

youtube link = http://www.youtube.com/watch?v=JT8zLTaKxeE

This is the link returned from Mytoolkit for this. MediaElement dies when I set it's Source to this Uri. Same error as posted above.

I really have no idea what these link parms are. Is there a reference page that lists the parms and what they mean?

[wisien92]

vevo vids working for me in 2.5.10, I'll investigate it further

[Breakthru001]

I am wondering if this is a problem where the .Net MediaElement cannot handle HTTPS links.

I found this bug report on this issue and the .Net Dev team closed it saying it will not fix it.
https://connect.microsoft.com/VisualStudio/feedback/details/934355/in-a-wpf-standalone-application-exe-when-the-source-of-a-mediaelement-is-set-to-a-https-uri-it-throws-a-nullreferenceexception

Is there a way to request HTTP (ie not HTTPS) links from MyToolkit? Does YouTube now require HTTPS?

[Breakthru001]

Quick update.

I believe I confirmed that the issue is that the .Net MediaElement cannot handle HTTPS links.

This is the link returned by MyToolkit.

The MediaElement throws this error
Exception thrown: 'System.NullReferenceException' in PresentationCore.dll

But the link opened with Windows Media Player, plays fine.

Ugh. MediaElement , what a POS. Thanks Microsoft. So glad I wrote my app with .Net controls.

[rajeshkomatlapalli]

Thanks for the update, It is working for me, for all Video IDs
@rico Suter

[Vinquer]

Working for me too with 2.5.10
Thanks a lot !

[RicoSuter]

Have you tried to just replace https with http?

[mediaexplorer74]

replace https with http?

Hello from 2023 year. I tried v 2.5.16 today. That (this) bug returned when I tried both https & http cases :(

Maybe, useragent obsolete... idk.

Update: I experimented https->http at my own code...
Maybe, you mean
public static async Task<YouTubeUri[]> GetUrisAsync(string youTubeId, CancellationToken token)
function in MyToolkit.Extented project ?
I'll try to download your MyToolkit src code....
