Hi, All
I am using DVRRDK 3.0. on DVRRDK.
I have run decode-display demo and show same contents on HDMI and VGA.
In /dvr_rdk/demos/mcfw_api_demos/mcfw_demo/demo_vdec_vdis.c , do some modify for tie hdmi and vga :
//Vdis_tiedVencInit(VDIS_DEV_HDCOMP, VDIS_DEV_DVO2, &vdisParams);
Vdis_tiedVencInit(VDIS_DEV_HDCOMP, VDIS_DEV_HDMI, &vdisParams);
It's work to show same contents on HDMI and VGA!
At this time, I read VPSS sysfs configuration :
cat /sys/devices/platform/vpss/system/tiedvencs
tiedvencs value is zero. why? Does it should be 3 for hdmi tied with hdcomp?
By the way, I want to show same contents (eg. QT application using /dev/fb0) on hdmi and vga display after system bootup.
How could I do? I have did below when boot:
echo 0 > /sys/devices/platform/vpss/display0/enabled
echo 0 > /sys/devices/platform/vpss/display3/enabled
echo 3 > /sys/devices/platform/vpss/system/tiedvencs
echo 2:hdmi,hdcomp > /sys/devices/platform/vpss/graphics0/nodes
./QT_application
But it's not works! Only hdmi display OK but vga fails.
Am I missing something?
Thanks!
Steven
