Hi,
I am attempting to capture SDI video input through the GS2971A video decoder. I am able to get an image through and out the component output on the DM368 EVM, but I can't seem to get the image to show the proper colors. When I configure the IPIPE data flow for SRC_FMT=3 (page 84 of the VPFE users manual), I can see some of text on a paper that I am viewing with the camera but the colors are all over the place. When I configure the SRC_FMT=0, I get a crystal clear image, but it's black and white.
The GS2971A outputs YCbCr 4:2:2 so I expect to have the SRC_FMT set to 3. I am also attempting to configure the resizer in continuous mode to convert the YCbCr 4:2:2 to YCbCr 4:2:0 so it is in the proper format for the H264 encoder. I also have the BT.1120 configuration set up per the VPFE manual.
The data flow for the YCbCr input seems much simpler than a raw input so I am struggling to see what I am missing. Are there any registers that I should focus on that would affect the color of the video feed when in this mode? For example, do the ISIF.SDOFST registers come into play when I am not writing to SDRAM from the ISIF (since I am piping directly to the IPIPE)?
Any suggestions on registers values that I should focus on would be greatly appreciated!
Thanks,
Randy Scheifele
