From 91de062f50c969d1613dd9881c275e58f228b3ac Mon Sep 17 00:00:00 2001 From: Luca Bonissi Date: Mon, 26 Jan 2015 07:38:17 -0300 Subject: [PATCH] [media] gspca_vc032x: Fix wrong bytesperline I found a problem on vc032x gspca usb webcam subdriver: "bytesperline" property is wrong for YUYV and YVYU formats. With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for pixel format conversion, the result is a wrong jerky image. Patch tested on my laptop (USB webcam Logitech Orbicam 046d:0892).
