Terminology around camera sensor interface module is confusing. MIPI CSI is supposed to be a camera serial interface. Cameras on Pinephone are connected via a 8-bit parallel interface.

I'm also not sure how they came up with 5Mpix in the datasheet, CSI can do up to 4800x4800 which is 23Mpix.

OTOH, 1080p@30fps is not attainable on the parallel interface, at least not with the cameras that are in the phone. It would require ~120MHz clock, and communication starts to break down at around 60-70MHz.

Looking at the pin description on page 24 of the A64 Datasheet, it looks like the 8 data pins (CSI_D0 … CSI_D7) are for a MIPI Camera Parallel Interface (CPI), but Allwinner is calling it "CSI" (MIPI Camera Serial Interface).

This is really confusing, but I am simply repeating what the A64 docs say.

Out of curiosity, what is the highest-resolution still photo anyone has taken so far on the PinePhone? Maybe I should list that in the table.

Is 1080p@15fps the best video anyone has managed so far with the PinePhone?

It's possible to do 1080p@20fps max. I tried a few days ago.

Recordings from the phone:

1080p@20fps: https://megous.com/dl/tmp/vid.mp4

720p@30fps: https://megous.com/dl/tmp/vid-720.mp4

Cam -> display latency test (50ms):

720x480@60fps is also possible: https://megous.com/dl/tmp/IMG_0375.MOV
