Bug ID: 49392
           Summary: Otter browser fails to play youtube videos
           Product: Wine
           Version: 5.10
          Hardware: x86
               URL: https://jztkft.dl.sourceforge.net/project/otter-browse
                    r/otter-browser-weekly333/otter-browser-win64-1.0.81-w
                    eekly333-setup.exe
                OS: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: mfplat
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Debian

As the title says, it keeps hanging at black video screen with spinning circle.

In the console:

017c:fixme:mfplat:session_get_service_GetService Unsupported service
{1092a86c-ab1a-459a-a336-831fbc4d11ff}.

Seesm to use wmfengine.dll from Qt which as far as i get it from google relies
on mfplat and friends

Could you attach +mfplat log too, I don't immediately see where in Qt code it
might call for such service.

Well, this might not be a wine bug after all, I installed this in VirtualBox
and really get the same behaviour...

I`ll do some more testing and update or resolve  this bugreport later

Ok, video`s do play when otter browser installed in "real" windows (10)

So probably wine-bug after all.

Real issue is likely about missing networking support in mfplat, starting with
this:

---
00c0:trace:mfplat:source_resolver_BeginCreateObjectFromURL 0000000049224190,
L"https://r1---sn-5hne6ns6.googlevideo.com/videoplayback?expire=1592347730&..."...,
0x1, 0000000000000000, 00000000002194D0, 000000004F7E37E0, 0000000000000000.

If browser tries too hard to enable hardware acceleration that might explain
why it doesn't work in vbox for you. Session fixme is likely secondary and
depends on EVR.
