Carlos,
What mode have you configured the VPFE in? This behavior that
you are observing sounds like the VPFE is in BT.656 mode where only the
clock and data lines are used and the VSYNC and HSYNC are encoded in the
data stream.

Subject: input data through 'video in' port (DC4)
Hello:
I am trying to import raw data from DC4.
First I modified 'encodedecode' sample program to get video data
without encoding or decoding. With that program I could see and dump
video data but... first surprise: HD and VD lines on DC4 seem to be
always '1'. Don't know how Davinci could know when a video frame (or
line) starts...
Then we attached our data source to DC4, and we put 1.8V to
'CAPTURE_EN' to 'disconnect' tvp5146. Davinci seems to ignore HD and
VD and start capturing frames depending on wich data is received. No
sense, since VDHOUT bit in CCDC_SYN_MODE is '0', so HD and VD MUST be
inputs.
I am using 'waitForFrame' function of 'encodedecode' app example to
wait for frames.
Any idea? Thanks,
Carlos
