V4L2. Select timeout??
Hello and thanks always.
I have written a program to change camera settings and take photographs with a UVC camera. For this I use V4L2.
First question:
After all the necessary preparation, I use select to take the photos.
select has a parameter for timeout.
What are the possible reasons for a timeout to occur??
the situation
Before I had a code that didnt set the settings properly but could take photographs. I modified the code and now the settings can be changed but now sometimes select finish with a timeout. I am wondering what could be the reasons for the change.
Before I set the settings before start the capturing. Now I do it after. other than that I didnt modify the code.
In any case, what could be making the timeout to occur I wonder
small question
what is VIDIOC_S_CTRL error 5???
