[Linux-uvc-devel] [SVN] Divide by zero fix

[Laurent P. <lau...@sk...>]

Hi everybody,

I commited a fix for the divide by zero problem. This shouldn't affect any of 
you, but I wouldn't mind some testing.

I also commited another small fix, VIDIOC_DQBUF now fills the timestamp field 
in the v4l2_buffer structure.

On a side note, I tried to benchmark the driver after someone reported a 1-2s 
lag during video acquisition. The good news is that the latency introduced by 
the driver (delay between tend-of-frame and image availability in user space) 
is around 10µs with a few peaks up to 2.5ms, which is quite good. I don't 
know yet how I could measure the delay introduced by the webcam itself.
