Using a Raspi to get GPS data on video - Raspberry Pi Forums

-

having used couple of raspi's on wee boat (running opencpn gps , ais), wondered if possible use raspi gps data on network video recorder (nvr).

use poe nvr 2 mast-mounted cams, 1 looking on bow, other on stern. nvr has 4 poe cam inputs, use 1 of these connect raspi third 'cam' record gps-position, -course, -speed , -time data. simple screen decoded data, nvr takes care of time , sync cam video etc.

have no idea how ethernet port of raspi cope poe 48v dc, dedicated cat cable cut easlily made. so, gps connected raspi connected nvr 'cam'.

leaves small matter how program raspi (!), gps sentences need decoded/extracted , presented ethernet port in ip video format (h.264 1280x1024). made this, ideas ?

w fr greetings, leo

done searching: need hdmi input , hardware hdmi > h.264 encoder. raspi has no input , has not enough speed , capacity encode hdmi signal.

add-on hardware available @ price of €200+ without raspi opted 'black box' encoder €135 cheapest/simplest one. can record chart display of navigation pc, combining cam images position , other navigation data.

anyroad, on next project !

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
