Text only. Video plays fine. With Potplayer it works fine.
share a minimal code sample we can test

Ok, I will try.If you can reproduce with VLC, but not with the d3d9 output, you need to figure out how to use d3d9 with libvlc.
I'd assume --vout=direct3d9 to work (don't use ":" for libvlc constructor). You can troubleshoot more by comparing logs in VLC and your app.
