Camera board • Re: V4L2 Camera HQ to H264 encoder efficiency (CM4)

Thanks Jamesh, 6by9,

So I looked in to ISP....found the following:
1. https://datasheets.raspberrypi.com/came ... cation.pdf the ISP specifications are still in DRAFT...maybe you can point me to latest documentation.
2.https://github.com/raspberrypi/libpisp this is the library to access ISP functionality.

I understand that the physical ISP different on CM4 and CM5.
3.Should i use this lib for CM4?
4.How smooth will be transition from CM4 to CM5, in case we will decide to move from CM4 ->CM5?

5.Will it be possible to use libisp on Buster? I'm using V4L2 directly without libcamera.
6.Is there documentation for libisp (I hope documentation from "1" will be enough)

Thanks
