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. Laurent Pinchart |
