Hello everybody! I use video session and in delegate method didOutputSampleBuffer I get CMSampleBuffer. That's all right. But at some point, I want to change the exposure to -2, +2 and make images from the buffer. I use the setExposureTargetBias method and everything changes successfully, but there is one problem - I need to understand when exactly the buffer with the changed value (-2.0, +2.0 etc.) will be. The description says what to use CMTime syncTime from the setExposureTargetBias closure, which will be the future timestamp of the buffer with applied changes, but here there is a complete mismatch - when I compare these syncTime timestamp with buffer from didOutputSampleBuffer, the exposure is still in the process of changing. How to determine that exactly this buffer (its time stamp) corresponds exactly to the time stamp at which exposure bias changes will already be applied?
