Motion - Mjpeg To YUV 420p Patch

mjpegtoyuv420p patch for Logitech Quickcam Pro

Description of Patch

Posted by KennethLavrsen from posting on MailingList

Hi

To use my Logitech Quickcam Pro for Notebooks had written a mjpegtoyuv420p function, with the help of libmjpegtools [1]. With this patch and the v4l2-patch im can use it with the linux-uvc driver.

Aditionaly i had to set LDFLAGS to "-lmjpegutils -llavjpeg"

No need to change or anything in motion , just get svn version , get the patch and apply it.

This patch requieres that you have installed mjpegtools package.
