Can't work in chenged resolution about bananapi-m2-zero-ov5640 HOT 7 OPEN

Where can I find CamLive.py?

from bananapi-m2-zero-ov5640.

After I set with BananaPi-M2-Zero-OV5640 img uploading, I can find the home/pi/software/python/LiveCam directory, and there's a sample file called LiveCamp.py. I used it for test.
I work in 680,480 mode but didn't work in 1290,720.
I use this opencv code to change resolution in LiveCam.py

cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1280)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 720)

The result is the same if I excute before run it:

sudo media-ctl --device /dev/media1 --set-v4l2 '"ov5640 2-003c":0[fmt:YUYV8_2X8/1280x720@1/15]'

I'm very sorry, but do we have the same OS?

@jeonhaeng,

I've tested the software and have the same results (not surprising).
Both the C++ and Python (LiveCam) app give the same errors. The limited amount of memory (500 MB) seems to be the problem. I'm afraid there is not much we can do about it. Luckily, streaming is still possible with 1280x720.
However, even 1280x960 is a bridge too far to stream.

Then only two mode streaming is possib;e and can't change resolotuion setting in python?

from bananapi-m2-zero-ov5640.

Indeed, correct.
