recorded area at imx708 for video too small

[LeifSec]

Similar to #595 now for imx708 (no zoom lens etc.) the video area is much smaller than the picture area.

I have already done rpi_update and reboot / power off /on.

libcamera-still -o libcamera_still.jpg

libcamera-vid -t 5000 -o libcamera_vid.h264

What resolution are you trying to record? But default rpicam-vid records 640x480, which will crop the field of view. Try adding --width 1920 --height 1080, that should give you the full FoV.

OK with --width 1920 --height 1080 it is the full sensor area:

but it does not look like that width and height are just the size of the centered recorded area and that there is no down sampling.

1080 x 768

this seem to have only much larger dimensions as 640 x 480

192 x 108 (larger again ...)

Does this mean that if I I want to record the full sensor area I always have to record with --width 1920 --height 1080and then do a down sampling of the resolution by myself?

No, you can ask the ISP to do the downsampling. You can do this with the following command:

rpicam-vid  -t 5000 -o libcamera_vid.h264  --width <width> --height <height> --mode 2304:1296:10:P

This will request the full FoV mode from the sensor, and scale down to any resolution you requset in the ISP. However, you need to match the 16:9 aspect ratio to ensure the ISP does not do any further crop of the FoV.

Ok rpicam-vid -t 5000 -o libcamera_vid_mod_800.h264 --width 800 --height 450 --mode 2304:1296:10:P produced full sensor area.

Thanks a lot.

P.S.:
Now I have to figure out how this is handles in pycamera2 ...
