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.
Under Debian/Ubuntu a camera utility "nanocams" is available for previewing 40 frames and picture taking. You can try it by following the commands below
sudo nanocams -p 1 -n 40 -c 4 -o IMG001.jpg
For more details about the usage of the nanocams run "nanocams -h". You can get its source code from our git hub:
git clone https://github.com/friendlyarm/nexell_linux_platform.git
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.
