Including ffmpeg library in AWS Lambda

Question

I'm trying to include the ffmpeg library with AWS.

drwxrwxrwx 2 root root        0 Dec 22 13:04 bin
    -rwxrwxrwx 1 root root 40166912 Dec 22 11:50 ffmpeg.exe
    -rwxrwxrwx 1 root root       30 Dec 22 13:04 version.sh

drwxrwxrwx 2 root root        0 Dec 22 16:35 node_modules
-rwxrwxrwx 1 root root      594 Dec 22 13:03 package.json
-rwxrwxrwx 1 root root      818 Dec 30 11:04 SplitFrames.js

Below is what's in the main js file, SplitFrames.js

var execute = require('lambduh-execute');
var validate = require('lambduh-validate');

process.env['PATH'] = process.env['PATH'] + ':/tmp/:' + process.env['LAMBDA_TASK_ROOT']

exports.handler = function(event, context, callback) {
    var exec = require('child_process').exec;
    var cmd = 'ffmpeg -version';

    exec(cmd, function(error, stdout, stderr) {
        console.log(stdout);
        callback(null, stdout);
    }); 
}

I test the function in lambda and it outputs nothing. Wondering how to include the ffmpeg library with AWS and node js. Any help is greatly appreciated.

It's unclear what problem are you trying to solve, could you please add it to your question?

From the extension it seems your are using wrong platforms binary there -rwxrwxrwx 1 root root 40166912 Dec 22 11:50 ffmpeg.exe, Lambda is using Linux kernel version – 4.4.35-33.55.amzn1.x86_64 (http://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html).

Instead of that you could use this node module https://github.com/eugeneware/ffmpeg-static which should contain all three big platforms, Linux, Windows included (installing binaries from 3rd party sites isn't good practice).

Make sure you get the execution path correct.
