bug in MediaSource.OpenAsync() (Windows.Media.Core.dll)

Question

Hello,
i'm developing an app in uwp and i have problem with this code:

private async Task<bool> CheckLink(string url)
{
    using (MediaSource ms = MediaSource.CreateFromUri(new Uri(url)))
    {
        try
        {
            await ms.OpenAsync();
            return true;
        }
        catch (Exception)
        {
            return false;
        }
    }
}

private async void Button_Click(object sender, RoutedEventArgs e)
{
    bool result = await CheckLink("https://tv.oranews.tv/live/oranews/index.m3u8")
    //...
}

This code crashes only with this particular url. With other url is ok. I tried to debug but the crash happens in native library Windows.Media.dll.
I hope this is the correct form to report this.

Hello,

Welcome to Microsoft Q&A!

I made a test with the m3u8 uri you post and also these two files you shared. I get a very interesting result. The uri in your original post works correctly on my side. But I will get exceptions when directly create MediaSource objects using the local m3u8. Maybe it should work when using uri.

Anyway, in my testing, the uir 'https://tv.oranews.tv/live/oranews/index.m3u8' works correctly. It is different result with yours.

This is the code I'm using:

             MediaSource ms1 = MediaSource.CreateFromUri(new Uri("https://tv.oranews.tv/live/oranews/index.m3u8"));

            await ms1.OpenAsync();

It would be better if you could share me the OS version of your device and target version of your app.

Thank you.
