OpenNI recording

I have noticed that OpenNI records video from Astra slower than real-time. In comparison with Kinect 1 (30 fps) I would say Astra recording looks about 20 fps. Anyone else tried to record using OpenNI?

Nevertheless, frame rate is real-time when viewing OpenNI live (without saving).



I have an Astra and I am trying to record a video. But failed.
Could you tell me how did you record video from Astra in detail? Thank you very much!

Are you using OpenNI2 from Orbbec?
