javascript - Node handbrakejs runs the code but doesn't output -

so have 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 , once complete following console message:

complete 

now here odd part:

the progress output not displayed in console , when attempt find file there no file :s

there no errors in console , nothing indicating went wrong?

does have ideas of might be?

when debug complete function able go this , following output:

might worth trying add missing parameters? use handbrake-js on linux system , performs expected these encoding options:

 var encodingoptions = {         input:  inputfile,         output: outputfile,         quality: 17,         optimize: '',         encoder: "x264"     } 

then, call:

hbjs.spawn(encodingoptions) .on('begin', ...)...; 

btw, need listen on.end event, , not on.complete. documentation:

"end" fired on successful completion of encoding task. follows begin event, progress in between.

"complete" fired when handbrakecli exited cleanly. not mean encode completed planned..
