Adjusting width and heigth of camera, PAL USB

Adjusting width and heigth of camera, PAL USB

Hi,

I'm currently running the c++ library on my computer (dell xps15, ubuntu 20.04) and for the default parameters of width and height (respectively 672 x 224) I am running at 10 fps for the PAL USB. However, while looking at your specsheet, it is supposed to be able to run at around 100 fps for this resolution. In the same way, if it is running at 10 fps, my resolution should be about 5280 x 1819. Is this normal? My opinion is that since it is not running on GPU, it's normal that it wont run as fast as expected. 

In fact, inside the header files, there is references to API doc. Maybe this doc could answer my question. Does it exist? If so could i get a link toward it, cant seem to find it.

Thanks!

Loic
