How do I `cv2.read()` two webcams at the same time?

[How do I `cv2.read()` two webcams at the same time?]

@tooz 

Is there any other way to read two webcams in one code?

I'm using Tinker Edge R. This device cannot read more than one webcam.

Two webcams were connected in the tinker edge.

`cv2.open()` works well for two webcams, but only one webcam can be read.

How do I `cv2.read()` two webcams at the same time?

just tested the cv2.imshow() function on my side and no errors shown. if the debian 10 os you're using is the official release from our website, python/ opencv pakages are built in the image; if you're using a third party debian 10 os, maybe follow this tutorial to get all the necessary libs/ pkgs installed: https://linuxize.com/post/how-to-install-opencv-on-debian-10/

Thank you very much.
I almost gave up.
I'll give it a try.

I have one more question.
Two webcams were connected in the tinker edge. 'cv2.open' works well for two webcams, but only one webcam can be read. How do I 'cv2.read' two webcams at the same time?

[cv2.imshow() isn't working [edge R]]

I installed devian10 on tinker-edge-r.

The following error occurred as soon as cv2.imshow() was performed with the test code.

And I try to apt-get install libgtk2.0-dev and pkg-config.
How can I resolve the error?

error: (-2:Unspecified error) The function is not implemented.
Rebuild the library with Windows, GTK+ 2.x or Cocoa support.
If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config,
then re-run cmake or configure script in function 'cvShowImage'

I've never seen Asus's reply.

Hello,

I have tried to flash my Tinker Edge R by using the Flash tool (GUI) and the image from Tinker Edge R Debian 10 V2.0.5.

In the GUI, I can select the image and my Tinker Edge R. I suppose my Tinker is in MASKROM mode.

I have followed the steps from the Flash tool GUI manual, but everytime I get the notification that the flas has failed and that I should restart the Tinker into MASKROM mode and should try again.

What goes wrong and how can I fix this?

With kind regards.

I got a same issue.

Can't flash devian v10.

It makes me crazy.
