ioverlay - SetColor Question

[Bimal Mehta]

I have question on IOVerlay - What exactly it is used for - Does it remove
color from the video and replace the other color -
GetColor and SetColor not working properly

I am looking for the Chroma Key Help - I don't understand where should I start
from ... I felt that ioverlay -setcolor getcolor might help .

I want to change the color selected to transparent and merge the othre video
with the existing one - known as Chroma key

Please tell me on what should I search further to do this things done...

Here are three choices:

• use the sample grabber (best solution probably for .NET)

• write a transform filter (as Roman suggested, DO NOT MULTI-POST, your post was deleted)

• find a third-party filter that does the job for you

This question has been asked a lot. Do a search on the newsgroups, for
example. The answers above have not changed.
