Package: luvcview
Version: 1:0.2.4-1
Severity: wishlist
Tags: patch
Now, luvcview supports only the video format of YUYV/yuv and MJPG/jpg.
The device of UVC might use other video formats.
For example, Macbook iSight is UYVY format.
I attach patch. This patch support UYVY format.
I tested on Macbook iSight only display.
Please apply this patch.
