[nodejs] FFMPEG for aws s3 bucket signed url not working in node js

[Ahmed Sharief]

I am trying to create thumbnails from an amazon s3 bucket signed url. I am
able to generate thumbnails when i run the command in terminal



ffmpeg -ss 00:00:02 -i "https://test-s3-bucket.s3.ap-south-1.amazonaws.com/user_gallery_assets/5b6936069ac2bf0602085367/gallery/images/5b7be08527641dee8c1f8134.mp4?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=xxxxxxxxx%2F20180821%2Fap-south-1%2Fs3%2Faws4_request&X-Amz-Date=20180821T095101Z&X-Amz-Expires=900&X-Amz-Signature=d7f81f4eed3d6c87c04dc1b0ad06beeb946afa33d417585f57fad72aeadb3ac0&X-Amz-SignedHeaders=host" -vframes 1 -q:v 2 -f image2 output.jpg

I am running the above command in terminal and its working fine but when i
try to implement the same in node js its showing "no such file or directory
error". Though i am encoding the url with double quotes then also its
showign same error. Here is my node js code....

function uploadThumbNailForVideo(obj,url, thumb_url){
return new Promise((resolve, reject) => resolve(url))
.then((url) => awsHelper.getImage(url))
.then((result) => {

var resUrl = "\""+result+"\"";

var args = [
'-i', resUrl,
'-ss', '00:00:02',
'-vframes', '1',
'-f','image2',
'output.jpg'
]
//console.log(args)
var ffmpeg = require('child_process').spawn('ffmpeg', args);

ffmpeg.on('error', function (err) {
console.log(err);
});

ffmpeg.on('close', function (code) {

});

ffmpeg.stderr.on('data', function (data) {
var tData = data.toString('utf8');
var a = tData.split('\n');
console.log("A",a);
});

ffmpeg.stdout.on('data', function (data) {
//
});


});

}



and i am getting the following error
