Not possible to scan more than one QR code #66

Closed Isolator70 closed 1 year ago

Isolator70 commented 1 year ago

Precondition:

After start of the application it is instantly ready to decode a QR-Code - this works fine. In case of an URL it can be clicked and Web Browser opens as expected.

Camera picture still shows the "scene" (frozen picture) of the moment when CoBang decoded the presented code.

Problem 1: It seems not possible to scan another QR-Code right now.

Action:

Switch decoding from camera to file and back to camera

Problem 2: CoBang now receives new frames from the camera (life picture), but does not decode QR-code anymore.

Workaround: Close and restart CoBang

Proposal: Add a button to start a new decoding process.

Linux Mint 21.1, Cinnamon, Flatpak installation

Hi @Isolator70 , when a QR code is decoded, the webcam video will be paused. If you hover the mouse over the video, you will see the Play & Pause button. You just click "Play" to start scanning other QR code.

Hi @hongquan, cool, I didn't recognise that. The opacity without mouse over it seems quite high, so it was hard to detect:

With the mouse on it, it can be clearly seen:

I will try increasing the opacity. Thanks.

The opacity has been increased in v0.10.0.
