Other Parts Discussed in Thread: TVP7002
Hi,
I am capturing video on HDMI input(sii1161A) and VGA input(TVP7002) on TI8168 EVM. I am selecting single input at a time.
My usecase is Capture->Dup->Display (HDMI/DVO2)
|
-> DEI(VIP_SC)-> ENC -> A8
While selecting display to DVO2 and capture from VGA, capture FPS increased(almost double) and capture frames are also dropped.
I tested below 4 cases.
Case 1: HDMI input to On chip HDMI display

case 4 is showing flickering video and freezing frames. FPS = 125, frames dropped = 27925.
I want to capture VGA input to DVO2 output.
