Ability to map Y/Pb/Pr inputs #39

Closed Namaneo closed 4 years ago

Namaneo commented 4 years ago

Hello,

After some research, and knowing that the OSSC can handle YPbPr through scart, how hard would it be to develop the ability to map each of the three inputs?

Let's take the example of the Wii : to force the console to output YPbPr, there's only two pins to jump on the motherboard (links below). However, in this mode, here's what happens:

YPbPr through scart seems to work that way instead:

Would it be possible to have settings allowing to map each YPbPr track to each RGB track, for this kind of purpose?

All said above is assuming that my sources are correct. Please tell me if I'm wrong or if I missed something !

Only Pb/Pr could be theoretically swapped as Y line carries sync and thus splits to video and sync inputs of the digitizer chip.

So there's no way to configure something like "Y comes from this SCART pin, Pb from this one and Pr from this other one"?

Yes, it cannot be done without HW modification.

Alright, too bad Thanks for answering anyway !
