Hello Laurent, I was experimenting with a web-camera integrated in my laptop and was extremely confused by non-monotonic timestamps coming from the uvc driver. In fact, the very first timestamp was bigger then the second every time I tried. This patch helped.
More details: 1. I'm testing with avconv -f video4linux2 -i /dev/video0 -codec copy test.mkv 2. Prior to applying the patch I was always getting "Non-monotonous DTS in output stream 0:0" errors 3. I'm using kernel version 3.6.8 (yes, that's old, I'm ready to upgrade if you really need that for debugging) 4. The camera is 5986:0100 Acer, Inc Orbicam Anything else I can do to help you with this issue? My real usecase is having a single-board computer capturing a steady stream from a UVC webcam (h264 pixel format) while keeping timestamps reasonably accurate (within 0.1s) for the future processing and spending as little CPU time as possible.
