What happens?

I am able to record the video after applying the filter (filterString = "colorkey=#3BBD1E:0.33:0.23") But, while recording the video, If i face camera towards a green screen camera does not make green color as transparent. It will capture green color also. My requirement is too make the green portion transparent when i face the camera to green screen/objects.

@saudet, I tried changing filterString by (filterString = "colorkey=#3BBD1E:0.43:0.33") There is no change while recording the video and also in output file

And, i am following the same code of URL https://github.com/bytedeco/javacv/blob/master/samples/RecordActivity.java And have just changed the filterString in the code with this (filterString = "colorkey=#3BBD1E:0.43:0.33")

Please help me out in resolving this
