Yes. 64512,65536 looks wrong, only the final endpoint is allowed to have this value. The downward step to 2048 is also not allowed as the function has to be monotonic.I have been investigating the cause of the color artifacts seen in the first frames.
It turned out that there was an issue in how I configured the PiSP decompand block.
...
The hardware processes every frame independently and should have no such delay.However, I discovered another issue:
For the first two frames, the decompand block does not appear to be applied.
...
Question:
Is it possible that the PiSP decompand block processing can be delayed by 2 frames?
This sounds like a request/configuration scheduling problem, somewhere inside libcamera. Are you still having this issue?
