Motion - Support Question 2009x 03x 19x 222302

YUYV not working with USB 1.1

Question

When I connect my webcam by a USB 1.1 port to my notebook and start motion, I get the message, that only the palette MJPG (MJPEG) is supported. When I connect my webcam by a USB 2 port to my notebook and start motion, I get the message, that the palettes MJPG (MJPEG) and YUYV (YUV 4:2:2 (YUYV)) are supported.

Because MJPG is not working right with the webcam (Corrupt image) I want wo use YUYV also with USB 1.1.

This problem was also reported on http://www.lavrsen.dk/twiki/bin/view/Motion/SupportQuestion2008x07x24x090621

The output when the webcam is connected by USB 1.1:

Answer

This was already answered in other support request it's not a motion issue but a USB Bandwidth and driver that reduces image and only allow to use:
