};

to change the mode use this simple script: 

#!/bin/bash



    

  1. This scripts changes the graphics. Graphic mode must be provided by first
    2. 

  2. parameter in this form:
    3. 




    

  1. grmode 720p-60
    2. 

  2. grmode 1920x1080@60
    3. 



grmode="$1"


  1. Disable graphics0 pipeline

echo 0 > /sys/devices/platform/vpss/graphics0/enabled

  1. Disable hdmi VENC

echo 0 > /sys/devices/platform/vpss/display0/enabled

  1. Set the new VENC mode

echo $grmode > /sys/devices/platform/vpss/display0/mode

  1. Enable HDMI VENC

echo 1 > /sys/devices/platform/vpss/display0/enabled

  1. Enable graphics0 pipeline

echo 1 > /sys/devices/platform/vpss/graphics0/enabled

List of timings and how to setup

Run this BASH test script to test all modes on the target.
