Harrumph, I asked the seller and she told me to get this product.
https://www.ebay.com/itm/RGB-Scart-Cable-for-NES-Console/262378445911?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649It says RGB scart cable for NES but its clearly composite. Still, it works on my tv screen. But when I turn off the OSSC, the game still plays. Okay so maybe I’m not doing this right, idk. But what does this mean?
Of course this works. SCART was designed to accommodate all of composite, S-Video, and RGB, plus audio, all on the same cable, and TVs equipped with SCART should be able to handle all of those formats from their SCART inputs; so, when you are using that cable to connect your NES directly to your display, it’s displaying the composite video from the console.
When you run that same cable to your OSSC, you should get sync and no image, because the OSSC is using that composite video signal for sync, and it’s not receiving the expected R, G, or B signals.
I’m not sure what you mean by “turn off the OSSC”.
So far this is what my connection looks like:
Computer desktop – 3.0 USB => Startech video capture box
Startech video capture box – HDMI cable => OSSC
OSSC – RGB scart cable => Radioshack switch box (Its so I can switch to different consoles)
Radioshack is input to the tv and output to the NES
These layouts are sometimes easier to follow if you start from the video source (NES) and describe the paths to your display and capture devices.
If I’m understanding this correctly, the composite output from your NES is connected to a RadioShack SCART switcher; the output of your SCART switcher is then split between your TV and the OSSC; and the OSSC is connected to your Startech capture device?
Anyway, on my stream screen, when I turn the OSSC on, I do get a grey screen. When the console is on and the OSSC is synced, its gone. And the LCD screen reads AV1: RGBS 262p 15.75kHz 60.12Hz
For the most part, this is normal; that grey screen is the test screen that the OSSC outputs by default when it’s first turned on, and then, when a valid input is selected, the test screen is replaced with the video source. If you’re using that composite video SCART cable, then, again, that explains why you get sync but no video. The only weird thing is that the NES is usually 60.08Hz, not 60.12Hz, but this may be related to a known issue with the OSSC’s refresh rate readout.
If I buy this product or this one, what should I connect what to what?

These likely won’t do anything for you, as they ostensibly only transcode RGB to YPbPr; they likely will not get you RGB or YPbPr from composite video. You specifically need a decoder that can convert composite video (and/or S-Video) to YPbPr or RGB. Unfortunately, RGB/YPbPr decoders are not easy to come by. Those that respect 240p, like the Kramer FC-4040 and FC-4044, are rare, expensive, and discontinued.
Right now, I think your best option is a RetroTINK 2X, which will take 15kHz video (specifically 240p@60, 288p@50, 480i@60, 576i@60, but not PAL60) and either passthrough or line-double to 480p/576p, with HDMI output. An RT2X could be used directly with your HDMI TV or AVR (cleanest in terms of setup), or it can be used with the OSSC via an active HDMI to VGA converter.
If you have a little patience, you should wait for VGP’s upcoming Koryuu decoder, which will be able to decode composite video and S-Video to YPbPr, which can be used directly with the OSSC.
And also to note, my friend said that all I need is an AV Breakout cable which has an S-video cord and rca & rgb cords and it connects to my startech capture box.
That AV breakout cable would only be useful if you’re going to hook the NES directly to your capture device. If you’re going to use an RT2X, or RGB mod your NES to use it with the OSSC, then you’ll have HDMI output to feed directly into your capture device.
One thing to note is that the NES and SNES are known for having a jittery output (something about a scanline being terminated early every other frame, resulting in an uneven sync cadence), which some displays and capture devices won’t tolerate, especially from HDMI inputs. The OSSC doesn’t compensate for this, but the RT2X does.
And I just watched a youtube video where someone compares the OSSC with the Fraimeister and he says it doesn’t want to work with streaming and says to go to the fraimeister. If it comes to that, then gaddamn I gotta’ spend more money. But I’m going to try the retrotink first.
As far as streaming goes, the Framemeister is probably your best bet, because it is capable of framerate conversion (so you can convert PAL 50Hz and off-spec sync sources to an even 60Hz), it can smooth out the sync quirks with the NES and SNES, is a proper scaler (versus the OSSC, which is a line multiplier), and gives you way more control over the image output, at the cost of about a frame of lag, which doesn’t matter to your viewers (and might not even make a difference to you).
