AW: Webcam in Delphi?

Funktioniert die Kamera denn, wenn du direkt vor dem Thin Client sitzt und die VM offen hast?
Ja und Nein.
Ja, die Win10 eigene Camera App geht, langsam aber es kommen Bilder.

Nein, alles was via DirectDraw arbeitet (VLC), vsampledemo_32 und ...
Code:
external 'AVICAP32.DLL' name 'capCreateCaptureWindowA';
... funktioniert nicht.

Die VM ist ein Win10Pro auf HyperV.

EDIT: Nichts desto trotz würde ich dich doch bitten mal dxdiag zu öffnen und zu gucken was geht.
Habe ich gemacht. Das gute alte dxDiag Wunderdingens.

Wir zerstören die Natur und Wälder der Erde. Wir töten wilde Tiere für Trophäen. Wir produzieren Lebewesen als Massenware um sie nach wenigen Monaten zu töten. Jetzt rächt sich die Natur und tötet uns.
