The RDK Media Streamer is much more than a multi-format, multi-protocol server that delivers your media rich content across multiple screens and platforms. The RDK camera software runs on RPi-0 deviceNormal Thumbnail will get YUV data from RPI-0 camera device and it will convert YUV buffer into JPEG image based on openCV and then stored generated JPEG image in local /tmp directory . This page dedicated to bringing up and validation of RMS Normal Thumbnail functionality in R-Pi Zero.

RDK-C Build Instructions for R-Pi
Code Block | ||||
---|---|---|---|---|
| ||||
$ sudo dd if="Image Name" of="Device Name" bs=4M Example: sudo dd if=rdk-generic-camera-image_default_20200130060729.rootfs.rpi-sdimg of=/dev/sdb bs=4M |
...
STEP 1:
Add require SSID and PSK in /etc/wpa_supplicant.conf file in below format
...
Code Block | ||||
---|---|---|---|---|
| ||||
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
ssid="RDK"
psk="Comcast1"
}
|
STEP 2:
Reboot the Target
After Reboot don't do step 1 and 2.
Note : Step 1 & 2 is only applicable for fresh target boot-up with new image.
STEP 3:
Modify needed resolution in rms configuration file
Supported Resolution:
SD:
Width - 640 , Height - 480
Width - 720 , Height - 576
HD:
Width - 1280 , Height - 720
FULL HD :
...
Modify resolution in below configuration file
cd /usr/local/rms/bin
vi rms.conf
Code Block | ||||
---|---|---|---|---|
| ||||
RRSIP=18.224.54.11
RRSPORT=81
ROOMID=rpi0
RRSSSL=0
WIDTH=1280
HEIGHT=72 |
After resolution modification need to reboot the target.
Note: This step is not necessary,it is depends on your resolution validation.
STEP 4:
WiFi connection is must needed for RMS validationneeded to copy captured JPEG Image from /tmp directory into your PC.
Check WiFi connection by using below command.

STEP 65:
check camera device there or not by using below command
...
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0-rdk-camera:~# ls /dev/video0 /dev/video0 |
STEP 7:
On Bowser of PC:
http://dh-livevid-dev.comcast.com/bryan/demov3/evoplayersTest.html
Need to modify roomid as rpi0
Press "PLAY" button in WebBrowser page.
...
STEP 6:
check rdkcmediaserver( RMS ) binary is running or not.if it is running then we need to stop RMS binary running because we can't able to validate Normal Thumbnail while running RMS application.
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0-rdk-camera:~# ps -Af | grep rdkcmediaserver
root 659 1 22 10:24 ? 00:00:43 ./rdkcmediaserver ../config/config.lua
root 4911 381 0 10:28 ttyS0 00:00:00 grep rdkcmediaserver |
if we get above status then need to do below step.
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0-rdk-camera:~# systemctl stop rms-launcher |
STEP 7:
Run rormal_thumbnail binary by using below command
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0-rdk-camera:~# normal_thumbnail |
STEP 8:
Get JPEG image from local /tmp directory.
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0-rdk-camera:~# cd /tmp/
root@raspberrypi0-rdk-camera:/tmp# ls thumbnail2020-06-28\:10\:33\:57..jpeg
thumbnail2020-06-28:10:33:57..jpeg |
STEP 9:
Copy JPEG image from your RPI /tmp directory into you local PC.
Code Block | ||||
---|---|---|---|---|

xxxxxx@yyyyy-Lenovo-B480:~/THUMBNAIL$ scp root@RPI_DEVICE_WIFI_IP:/tmp/thumbnail* .
Example:
xxxxxx@yyyyy-Lenovo-B480:~/THUMBNAIL$ scp root@192.168.43.246:/tmp/thumbnail* .
