hdvpss - video output with SD composite

Hello,

I am using vision Mid EVM and hdvpss_01_00_01_42.

I have saw the example in hdvpss_01_00_01_42\packages\ti\psp\examples\common\vps\chains

My capture is 5158 and it only supports HDMI display (CHAINS_DISPLAY_ID_HDMI_ONCHIP / CHAINS_DISPLAY_ID_HDMI_OFFCHIP)

How should I do if I need to output SD composite?

Thank you very much!

Hello,

You could try the latest EZSDK 5.05.02. There is support for SD display in OMX capture_display example.

Also you should change:

echo 0 > /sys/devices/platform/vpss/display2/enabled
echo "composite" > /sys/devices/platform/vpss/display2/output
echo 1 > /sys/devices/platform/vpss/display2/enabled

Best Regards,

Margarita

Thank you for replay.

Now I can see the capture, but the color is incorrect.

The frame only displays "black and white", no red, blue.....etc. (even the color bar)

Is there any suggestion?
