Thanks JHPJHP & Caronte3D for your help.

Can confirm the demo.pb now works on my machine!! - there appears to be some small changes between 2.1 and 3.0 demo code.

Going to make the changes to my code later to reflect this and try it again.

Thanks Caronte3D,

The camera output is being used for homebrew machine vision (not OpenCV!) and in my prototype runs at either 2 or 10Hz (throttled on purpose).

The problem is registering the damn escapi.dll (machine is Windows 10, Defender as AntiVirus). It worked fine initially for a few hours ...

Code here (thanks Caronte). This requires escapi.pb and escapi.dll (https://solhsa.com/escapi/index.html) I've been using 2.1

I put "escapi.pb" and "escapi.dll" in the same folder as the code below:

demo.pb

XIncludeFile "escapi.pb"

device = 0

count = setupESCAPI()
Debug "init: " + Str(count ...

So I've abandoned VfW in favour of ESCAPI (V2.1)

I got it working for a couple of hours (escapi.dll in the same directory as my project code). Lovely. Then it stopped working. :shock:

Basically something is now stopping it finding escapi.dll, so I tried adding escapi.dll to Windows/System32 ...

Hi,

I'm trying to display video from a low cost USB video capture device (from Amazon), whilst displaying the video I also want to capture stills for further processing.

I know the capture device works in the standard Win10 webcam app and OBS. I found various bits of sample code on this forum ...

Thank you blueb. Is there a way of doing this without rhe SetWindowCallback?

Is there a method of detecting a mouse click/press for a column header in ListIconGadget?

Thanks. I'll have a look.

Yeah.

I'm building a complex GUI for a PC connected electronic instrument.

There is realtime data being displayed (graphs), as well occacsionally updated image (graph backgrounds/historical data), user interactive buttons (essentially static) as well as fastmoving number displays, mouse sprite and ...

I have left the adjust framerate feature in my SW so if someone runs it on an ancient machine it will still work.

To lower the overhead I reworked the way the graphics is(was) generated (basically stop regenerating the complex graph background each frame).

No, I'm using SetFrameRate for my experiments.

SetFrameRate(0) - causes program to crash with: "SetFrameRate(): Frame rate can't be less than 1."

Is there a way to unset (i.e. set to default) the framerate if it is set?

Submit the executable that creates the false positive to microsoft and McAfee as false positive. This has happened repeatedly in the past with different AV products and currently there is no easy fix to avoid it happening in the future.
