I have a Pi3 with a OSOYOO 3.5 Inches LCD Touch screen ( https://smile.amazon.com/gp/product/B01 ... UTF8&psc=1 ) and am looking to create sort of a dual-screen media center for my car.
My car has built-in screens in the roof for the back-seats for the kids, and it has a built-in dvd player, and composite inputs. I am hoping to use the pi streaming to the composite inputs (so I can do long playlists on long drives instead of constantly swapping or burning dvds) but keep the actual pi and bolted-on lcd up front so my wife and I have control of play/pause and video selection. There is no good way to see the screens in the back from the front seat, so traditional mouse/keyboard input would be useless, and the bolted-on LCD has too low of resolution to be reasonable to mirror.
I have some thoughts on how to do this, and I haven't seen a similar project, but want to know if there's another way. I heavily use awesomewm and am very familiar with building rules to control what windows go on what screen. I was gonna set the whole thing up like a xinerama X session with 2 screens, the composite screen and the touch screen, then use vlc with a separate control window to play the media. I don't know if that's gonna work well or not, but I'm proceeding.
Would anyone do something substantially different to accomplish the same goal?
