avconv

simply spawns an avconv process with any parameters and returns the result to you. very small, fast, clean and does only this.

installation

to install find-delete, use npm:

$ npm install avconv

then in your node.js app, get reference to the function like that:

var avconv = require('avconv');

quick example

make an avi video out of images

var params = [
    '-f', 'image2',
    '-loglevel', 'info',
    '-i', '/tmp/images/',
    '-y', '/tmp/output.avi'
];

avconv(params, callback);

(avconv consultation is not subject of this module. if you need help with parameters, have a look at http://libav.org/avconv.html)

callback(code, stdout, stderr)

three parameters are always passed onto the callback:

function callback(code, stdout, stderr) {
    // add your logic here
}

code = 0 (zero) means there was no problem. an exit code of 127 means the program avconv could not be found. i recommend you to use a switch block to deal with these error codes.

stdout might contain any useful information, depending on the log level. stderr will have any warnings or error information in case of a problem.

api

avconv(params, callback)

avconv spawns a new avconv process with any given parameters. it does not validate the parameter nor the results. that's all up to you.

arguments

• params - any array list with string arguments
• callback - the callback function to be called when process is finished. it passes three parameters:
  • code - any integer where 0 means OK. anything above 0 indicates a problem (exit code).
  • stdout - a string with useful information, depending on the log level.
  • stderr - a string with potential warnings or errors.
