Well, that's what you get for using a barely-tested signal source that doesn't even claim to be HDMI-compatible ;)

Re: Need more help with Pluto II HDMI, red blue color problem

Update: I can get good color output through the card's HDMI output if I stay down at 480i AND turn off linedoubling . But if I turn on linedoubling, or if I try to switch to progressive scan 480p the colors invert again. See attached picture… This tells me the card is receiving accurate colors, and...

Re: Cloning the GameCube component cable

What can cause this? Could be interference from the pixel clock - the GCVide Lite board seems to have a problem with this, although I don't know why it happens. It's not that noticable with a Gamecube as the interference is pixel-aligned and the Cube's resolution matches the sampling rate of the di...

It would work only for shifts of a few pixels, not for such an extreme offset as shown in your picture.

Re: Cloning the GameCube component cable

VSYNC fluctuates wildly and is anywhere from 60Hz to 1kHz according to my multimeter. HSYNC is about 32kHz. HSync sounds ok, VSync probably is also ok since you get a stable image. Some multimeters are a bit too sensitive in the frequency ranges and read a bit of noise on the line as signal instead...

Re: Problem at Programming GCVideo lite

The FPGA is receiving power on all rails like it should be (3.3V directly from the Gamecube Regulator Board). After the renewal of my board i am now 1 step further. Now i get a "Identify Succeeded" on the Workspace. The Workspace stays Empty though. You shouldn't need to load a BSDL file to use Imp...

Does your multimeter have a frequency range? If so, try measuring the frequency of the VSync and HSync outputs on the GCVideo-Lite board.

Re: Cloning the GameCube component cable

The 54Mhz isn't cause the interference, thats the line we are trying to keep clean. Actually it goes both ways - you want a clean clock signal to sample everything else with and you don't want that clock signal to interfere with the signals you are trying to read. I'm just saying in my experience, ...

Re: GCVideo Lite on N64

Green cable in composite doesn't show anything, same deal on component as well. With my multimeter, I get a lot of different frequencies on the H and V pins, there weren't any clear values, and I didn't see 15kHz or anything that close to it. Most of the values were around 2 - 5 kHz. That could ind...

Has anyone else successfully programmed a GCVideo lite using the .svf file on the github? Yes, a long time ago to verify that it actually works - but only using Impact to program a Lattice chip. So I'm not getting ANYTHING at all on any of them, which just strikes me as odd. But I feel like I've at...

Re: Program Shuriken Video V3 Please Help!

I measured 2.1v at that pin to chasis ground. I've expected 1.8v but never actually measure it without the PCB. I think this is the GC listening high and your board doesn't work. If works it should be 3.3v. Although the table on the GameSX-Wiki says "pull high 1.8v", I found that this is actually j...

I think 2.2 might require the IR sensor to be connected else it will fail to initialize correctly.

Checkerboard over the output means that the OSD-CPU did not initialize its video RAM, so you see the default pattern which was chosen to quickly indicate this. I have no...

What if I want to upscale chroma using jinc or bilateral filtering, or the super-resolution algorithm of the year? Even if I would implement YCbCr outout, it would be 444 and not 422.

Just because it is specified in HDMI 1.0 does not mean that every device with an HDMI input is required to support it.

Also, why do you think it would provide any advantage over the current RGB conversion in GCVideo?

Re: Cloning the GameCube component cable

Extrems wrote:When's Y'CbCr passthrough over HDMI?
Never. To do this properly, GCVideo would need to check the EDID data from the display to determine if it supports non-RGB formats and that is too much of a pain to implement and probably won't fit in the remaining space either.
