Copy CMSampleBuffer attempt using CMSampleBufferCreateForImageBuffer.swift

Hi, did you hardcode the timingInfo value?

@fukemy I asked on StackOverflow and received this very helpful answer: https://stackoverflow.com/a/38362579

Note that this was done nearly 7 years ago so iOS may have changed since then.

your solution is the best i have found, other is using CIContext.render() method. It's took much CPU. Thanks a lot anyway

I noted that Copy the pixel buffer will make slower, just make a create and do not copy any would be better
