[HOW-TO] Know USB camera resolution #526
Comments
can you use |
For a usb cameras I tried
Experiment shows that picamera2 generates a stream from a usb camera that can have discrete values of "size". |
what about |
Hi, I'm afraid USB camera support is limited with Picamera2, and we have no plans to extend it at the moment. You could try whether |
Please only ask one question per issue!
I want to get the best possible usb resolution, for still image capture. How do I know what I can specify?
Describe what it is that you want to accomplish
By default usb camera resolution appears to be 640x480 for both YUYV and MJPEG
This seems good for a
4:3
preview.I want higher resolution for a still capture, I expect the resolution to depend on the usb camera used.
Describe alternatives you've considered
I tried setting a plausible, and higher resolution:
If in a still_configuration I set
main = {'size' : (1440, 1080)}
I get a capture that is
1600 x 896
, so it seems there is more resolution to be had.But this is not the size I asked for, and is not
4:3
it is16:9
Configuring higher resolutions, showed similar behavior.
