问题描述
所以我为 hq 相机制作了一个相机应用程序，但我无法在我的 raspberry pi 4 上拍摄任何类型的照片！
from guizero import App,PushButton
from picamera import PiCamera
camera = PiCamera()
app = App()
def preview():
camera.start_preview(fullscreen=False,window = (50,150,2048,1152))
button = PushButton(app,command=preview,text="preview")
def stop_preview():
camera.stop_preview()
button = PushButton(app,command=stop_preview,text="stop preview")
def shutter():
camera.capture('/home/pi/Desktop/image.jpg')
button = PushButton(app,command=shutter,text="shutter")
app.display()
但由于某种原因我收到了这个错误！
mmal: mmal_vc_port_enable: failed to enable port vc.ril.image_encode:out:0(JPEG): ENOMEM
mmal: mmal_port_enable: failed to enable port vc.ril.image_encode:out:0(JPEG)(0x1e258a0) (ENOMEM)

我也尝试制作代码单独捕获！
from picamera import PiCamera
from time import sleep
camera = PiCamera()
camera.start_preview()
sleep(5)
camera.capture('/home/pi/Desktop/image.jpg')
camera.stop_preview()
注意！：尝试获取错误代码，但在执行后我卡在预览中！但除此之外，如果没有预览，我就明白了！
