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"
