I wonder if there are more sample examples #5

Hey,

I wonder if more sample examples could be provided, I am currently using this wrapper with PyQt5 to show live video, but O really can't understand how to figure it out.

Thank you!

Yes examples would go a long way. I'm considering purchasing a camera for use with this software. I'm planning to go for python first and fall back to the supported C# if I can't get library working. I will gladly contribute my own examples if/when I have them but first I need to get off the ground.

Apart from capturing images and supplying you with pixel arrays there is very little this library will do for you. If you want to display video, use a generic toolkit and get that going with random data (no pyflycapture2), then plug in pyflycapture2.

Here is another example https://github.com/jordens/bullseye/blob/master/bullseye/flycapture2_capture.py

Hey Jordens,

Thank you for the update! But I don't think it helps with my problem. Now I have an array from "retrieve_buffer" with size of 1024 * 768, I wonder how I can display it on the screen? Is it grey picture?

Thank you!

there is no problem here. the array is just what your pixels see. if you have r-g-b pixels you have to figure out how to do the interpolation. plotting pictures is done with any other library.

Thanks Jordens that makes sense. So in theory I should be able to plug the RGB array returned from this library into PIL's putdata function and then save it. Would you prefer such a script be pull requested to your repo here or should I keep it separate?

it is not an rgb array. if you sensor is rgb, the data is the bayer grid. this is all explained in the documentation. i don't think "saving an array with pil" is a helpful addition.
