    Description

      Using the media-player example ("player"):

      The player compiles fine, but if I try to open different media files, some types will fail, all with the same error:

      DirectShowPlayerService::doRender: Unresolved error code 80040266

      I tested the following types:

      • .mp4
      • .mkv

      I tested .wmv too, but those worked. I tested all files using the Windows 10 Media-Player and VLC-mediaplayer - all worked fine.

      Update:
      I tested some more with 5.6 and got the following, interesting results:

      • Msvc 2015 x64: Shows the error code
      • Msvc 2015 and mingw x86: No error code, but will fail nonetheless
      • Msvc 2015 WinRT x64: No error and the video plays, but you can only hear sound, no display!

      I'm not shure what this means, but it may help.
