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 !

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
