STEP 2:

This step only needed for Libcamera validation

Add below configuration in end of the /boot/config.txt file

dtoverlay=imx219

core_freq_min=250

Code Block

language	bash

vi /boot/config.txt

dtoverlay=imx219
core_freq_min=250

STEP 3:

CVR validation using v4l2 & Pipewire

If the below configuration there in config.txt file then please disable for this v4l2 and pipewire validation

Code Block

language	bash
title	v4l2 : Console output

vi /boot/config.txt

#dtoverlay=imx219

2. CVR validation using libcamera

Enable dtoverlay and minimum freq configuration in config.txt file

Code Block

language	bash

vi /boot/config.txt

dtoverlay=imx219
core_freq_min=250

STEP 4:

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 35:

WiFi connection is must needed for CVR-AWS validation.

STEP 68:

Before triggering CVR binary we should stop rms binary and mediastreamer binary with below command because currently we can't able to validate RMS and CVR feature at the same time.

systemctl stop rms-launcher

systemctl stop pipewire-launcher

systemctl stop mst-launcher

STEP 79:

Preload the below library files for omxh264enc plugin.

export LD_PRELOAD=/usr/lib/libwayland-client.so.0:/usr/lib/libwayland-egl.so:/usr/lib/libopenmaxil.so

STEP 810:

Before start the CVR binary please check the current date and time in RPI with "date" command, If you get wrong date and time please manually set current date and time with the below command.
