So I have the following code:
var hbjs = require('handbrake-js');
var encodingOptions = {
input: media.file.path,
output: media.targetDir+"helloWorld.m4v",
quality: 17,
optimize: '',
encoder: "x264"
};
hbjs.spawn(encodingOptions)
.on("begin",function(){
console.log('begin')
})
.on("error", function(err){
// invalid user input, no video found etc
console.log('error!')
})
.on("progress", function(progress){
console.log(
"Percent complete: %s, ETA: %s",
progress.percentComplete,
progress.eta
);
})
.on("complete", function (complete) {
console.log('hello');
})
This code runs and once complete I get the following console message:
complete
Now here is the odd part:
The progress output is not displayed in the console and when I attempt to find the file there is no file :S
There are no errors in the console and nothing indicating that something went wrong?
Does anyone have any ideas of what this might be?
When i debug my complete function i am able to go into this and get the following output:

Encode done!
HandBrake has exited.
Might be worth trying to add some missing parameters? I use handbrake-js on Linux system and it performs as expected with these encoding options:
var encodingOptions = {
input: inputFile,
output: outputFile,
quality: 17,
optimize: '',
encoder: "x264"
}
Then, you will call:
hbjs.spawn(encodingOptions)
.on('begin', ...)...;
BTW, you need to listen to the on.end event, and not the on.complete. From the documentation:
"end" Fired on successful completion of an encoding task. Always follows a begin event, with some progress in between.
"complete" Fired when HandbrakeCLI exited cleanly. This does not necessarily mean your encode completed as planned..
