Some questions timeout in rc_dev

2014-02-16 Thread Rune Petersen
Hi, The intent of the timeout member in the rc_dev struct is a little unclear to me. In rc-core.h it is described as: @timeout: optional time after which device stops sending data. But if I look at the usage, it is used to detect idle in ir_raw.c which again is used by the RC-6 decoder

Hello V4L2 people. I'm working on camera device drivers over 5M pixel and made drivers based on V4L2 API. Actually I'm still working on it. By the way, I have some questions in exposure control. If my guess is right, V4L2_CID_EXPOSURE_* CIDs are what I'm looking for. Control
