Hello, I'm trying to get a labtec 2200 usb webcam working on my custom ARM platform. Since that webcam produces only images in pjpeg, I'm using libv4l2. I wrote a simple capture application where I want to read a single image in rgb24. When the application invokes v4l2_read I get the above error. The error comes from mmap which is invoked in libv4l2, but I've no idea whats wrong there. Can someone give me a hint how to fix this?
