Hi,
i have read the follow discussion,but it still can not work.
And if plug the video signal in before the application start, there is no video on the screen.
http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/222543/787692.aspx#787692
here is my usercase :
capture--->dei--->displayt ,
the signal is connected at vip1_portA. with BT.656 (PAL). 8bit mode.
My platform is DVRRDK_03.00.00.00, Would you please tell me how to modify to PAL mode, thanks!
here is my usercase code,please help me correct the follow code
