How to Record at runtime?

Hello,

I am looking all over the web for a way to record my scene from the final executable.

I have a scene with a direct media player (it get data from external camera)
I add Chromakeying to it, so the green background is not visible anymore
I now whant to record this video playing as a file.

All i found yet is a plugin (framcapturerecorder) but is not working … for 100 secs of record i only get a speedy video of 38 secs.

I also try with the replay system but can’t get it working.
