From 697a6d2387692c7f9c94f3bfb3dac474aa840f02 Mon Sep 17 00:00:00 2001 From: Katsuya Matsubara Date: Tue, 23 Apr 2013 07:51:37 -0300 Subject: [PATCH] [media] sh_veu: fix the buffer size calculation The 'bytesperline' value only indicates the stride of the Y plane if the color format is planar, such as NV12. When calculating the total plane size, the size of CbCr plane must also be considered.
