Video Player mit DEV-C++ machen
-
Ich würde gerne einen Videoplayer programmieren in DEV-C++ programmieren, aber ich bin noch ein absoluter Anfänger. Ich habe schon ein Beispielprogramm aber beim kompliieren scheint das Programm andauernt bei einer Datei hängen zubleiben. Es ist aber kein Fehler. Das ist die Datei:

Bei google.de finde ich nichts...nützliches
. Vielleicht könnt ihr einem Neuling helfen.
Danke

Du bist im falschen Forum gelandet: hier werden Auftragsarbeiten vergeben (gegen Bezahlung), oder leute fuer ein unentgeltliches Projekt (meist open source) gesucht. Wenn du schildern kannst, wo genau du ein Problem hast (nicht 'der runtergeladene code kompiliert nicht'), dann verschieb ich dich gern in das entsprechende Forum.

Upps dann bin ich hier wirklich falsch. Ich will nur einpaar Codes kennen mit deem man seinen eigen Videoplayer machen kann. Oder auch einpaar Links zu Beispielen.
