Photo exit event never fires.

[ghost]

Hi @troyth @dsteinborn @markelarizaga @mattmcneeney !

Not sure if this repo is still being maintained, but I've run into an issue.

Using the example code in "eg/photo.js" for capturing a photo, but the "exit" event never seems to fire. In fact, it seems to be stuck in some kind of loop. Note that I had to run control-C to kill the process manually.

Output:

Code:

var RaspiCam = require("../lib/raspicam");

var camera = new RaspiCam({
    mode: "photo",
    output: "./photo/image.jpg",
    encoding: "jpg",
    timeout: 0 // take the picture immediately
});

camera.on("started", function( err, timestamp ){
    console.log("photo started at " + timestamp );
});

camera.on("read", function( err, timestamp, filename ){
    console.log("photo image captured with filename: " + filename );
});

camera.on("exit", function( timestamp ){
    console.log("photo child process has exited at " + timestamp );
});

camera.start();

Notice: using Raspberry Pi 2, running Raspbian, and using official Raspberry Pi camera, with latest version of this node module Raspicam.

I could never get exited event to fire but the following did stop the endless loop of taking photos:

camera.on("read", function(err, filename) {

    if(!err) {
        console.log('Photo taken and saved');
    } else {
        console.log('Error taking photo!');
    }

    camera.stop();
});

camera.start();
