1 Run Qt 5.10.0 Demo with GPU acceleration

Run the following command

$ sudo qt5demo

S5pxx18-QtE

2 Run Qt 5.10.0 Demo with OpenGL

Run the following command

. setqt5env
cd $QTDIR
cd /examples/opengl/qopenglwidget
./qopenglwidget

For more Qt 5.10.0 examples, please go to:
cd $QTDIR/examples/

3 Play HD Video with Hardware-decoding

gst-player is console player, it base on GStreamer, support VPU with Hardware-decoding: 

sudo gst-player /home/pi/demo.mp4

The equivalent gsteamer command is as follows： 

sudo gst-launch-1.0 filesrc location=/home/pi/demo.mp4 ! qtdemux name=demux demux. ! queue ! faad ! audioconvert ! audioresample ! alsasink device="hw:0,DEV=1" demux. ! queue ! h264parse ! nxvideodec ! nxvideosink dst-x=0 dst-y=93 dst-w=1280 dst-h=533

4 Connect to DVP Camera CAM500B

The CAM500B camera module is a 5M-pixel camera with DVP interface. For more tech details about it you can refer to Matrix - CAM500B.
Enter the following command to preview the video： 

gst-launch-1.0 -e v4l2src device=/dev/video6 ! video/x-raw,format=I420,framerate=30/1,width=1280,height=720 ! nxvideosink

Enter the following command to start recording (VPU hardware encoding)： 

gst-launch-1.0 -e v4l2src device=/dev/video6 ! video/x-raw,format=I420,framerate=30/1,width=1280,height=720 ! tee name=t t. \
 ! queue ! nxvideosink t. ! queue ! nxvideoenc bitrate=12000000 ! mp4mux ! \
 filesink location=result_720.mp4

5 Power Off and Schedule Power On

“PMU Power Management” feature helps us to auto power on the board at a specific time, it is implemented by an MCU, support software power-off, and RTC alarm power-up functions.

Here’s a simple guide:
Turn on automatically after 100 seconds. (Time must be greater than 60 seconds.): 

$ sudo echo 100 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

After setting up the automatic boot, turn off board with the 'poweroff’ command: 

$ sudo poweroff

Cancel automatic boot: 

$ sudo echo 0 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

Query the current settings, in the front is current time, followed by the time of automatic booting: If no automatic boot is set, it will display "disabled”. 

$ sudo cat /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm


Note that some older versions of hardware may not support this feature, if you don't see this file node in your system:
/sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm
your board may be it does not support this feature.
