Mal ne Frage an die Cracks hier im Verein oder auch sonst wo... kann jemand von euch Phyton programmieren? Hab hier folgende Aufgabe und kein Plan:

Video-Konverter haben die Aufgabe, Einzelbilder eines Videodatenstroms einzulesen und in ein anderes
Format zu transportieren. Beispielsweise kann ein unkomprimiertes Video als Quelle dienen welches
dann in ein MPG-Video gewandelt wird. Zu Beginn m¨ussen diese Konverter-Programme oftmals eine
Farbraumtransformation vornehmen. In dieser Aufgabe sollen RGB-Einzelbilder in den YUV-Farbraum
konvertiert werden.
Schreiben Sie hierzu ein Python-Programm welches ein BMP-Bild (im RGB-Modus) einlesen kann und
zeilenweise die Farbwerte der einzelnen Pixel in RGB ausgibt. Berechnen Sie nun f¨ur die einzelnen Pixel
die YUV-Werte und geben Sie diese ebenfalls aus.
Benutzen Sie dazu folgende N¨aherung:
y = r * 0:299000 + g * 0:587000 + b * 0:114000
u = r * -0:168736 + g * -0:331264 + b * 0:500000 + 128
v = r * 0:500000 + g * -0:418688 + b * -0:081312 + 128
Was bewirkt der Summand 128?

Jemand der sich auskennt und helfen kann?
