for Exynos4412(mali)

1080P(Full HD)

Tumblr.

720P -> enable Portrait HDMI Screen

1080P -> not allow Portrait HDMI Screen.

device/samsung/exynos4/libhdmi/libhdmiservice/SecTVOutService.cpp

291 void SecTVOutService::setHdmiRotate(uint32_t rotVal, uint32_t hwcLayer)
292 {

294 // 1080p is spec out.

Add init.d support to ODROID

Add init.d support to ODROID

create sysinit script device/hardkernel/proprietary/bin/sysinit

#!/system/bin/sh

export PATH=/sbin:/system/sbin:/system/bin:/system/xbin
/system/bin/logwrapper /system/xbin/run-parts /system/etc/init.d

edit device.mk

# init.d support
PRODUCT_COPY_FILES += \
device/hardkernel/proprietary/bin/sysinit:system/bin/sysinit

edit init.odroidu2.rc

on boot

# Run sysinit

start sysinit

...

# sysinit (/system/etc/init.d)

service sysinit /system/bin/sysinit

user root

oneshot

build android

why support init.d?

Must do 98netflix script for Netflix service.

OpenCV test on ODROID-X2.

Download OpenCV test app

http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.4.5/OpenCV-2.4.5-android-sdk.zip/download

import projects to eclipse.

OpenCV Library - 2.4.5
OpenCV Sample - face-detection

add NDKROOT variable

fix preview parameters

JavaCameraView.java

params.setPreviewFormat(ImageFormat.NV21);
Log.d(TAG, "Set preview size to " + Integer.valueOf(640) + "x" + Integer.valueOf(480));
params.setPreviewSize((int)640, (int)480);
//Log.d(TAG, "Set preview size to " + Integer.valueOf((int)frameSize.width) + "x" + Integer.valueOf((int)frameSize.height));
//params.setPreviewSize((int)frameSize.width, (int)frameSize.height);

for MIPI Camera.

//params.setPreviewFormat(ImageFormat.NV21);
params.setPreviewFormat(ImageFormat.NV16);
Log.d(TAG, "Set preview size to " + Integer.valueOf(640) + "x" + Integer.valueOf(480));
params.setPreviewSize((int)640, (int)480);

How to Use WebCam(UVC) for ODROID-X/X2

1. Module UVC driver

--- V4L USB devices
<M> USB Video Class (UVC)
[ ] UVC input events device support
<M> GSPCA based webcams --->

2. make and copy zImage
$cp arch/arm/boot/zImage android/device/hardkernel/odroidx[x2]/kernel_sdmmc[emmc]

3. copy uvcvideo.ko
$cp driver/media/video/uvcvideo.ko android/device/hardkernel/proprietary/bin/

4. copy driver into "/system/lib/modules/" directory.
device.mk
#
# UVC Module
#
PRODUCT_COPY_FILES += \
device/hardkernel/proprietary/bin/uvcvideo_x.ko:system/lib/modules/uvcvideo.ko

5. add service for module insert.
init.odroidx[x2][_realtek].rc

service uvc_usb_module /system/bin/insmod /system/lib/modules/uvcvideo.ko
class core
user root
group root
oneshot

6. select WebCam Camera library.
BoardConfig.mk
BOARD_CAMERA := odroidx //MIPI cameara
BOARD_CAMERA := odroidu //UVC

7. android build
