# ffprobe
Use ffprobe to get info from media files and return as JSON
[](http://travis-ci.org/eugeneware/ffprobe)
## Installation
This module is installed via npm:
``` bash
$ npm install ffprobe
```
## Example Usage
`ffprobe` is a *dual* API, supporting both node.js callbacks *AND* `Promise`s.
### Callback API
List the output of ffprobe for a media file in a convenient JSON format:
``` js
var ffprobe = require('ffprobe'),
ffprobeStatic = require('ffprobe-static');
ffprobe('./file.mp4', { path: ffprobeStatic.path }, function (err, info) {
if (err) return done(err);
console.log(info);

### Promise API
List the output of ffprobe for a media file in a convenient JSON format:
``` js
var ffprobe = require('ffprobe'),
ffprobeStatic = require('ffprobe-static');
ffprobe('./file.mp4', { path: ffprobeStatic.path })
.then(function (info) {
console.log(info);
/***

{
"index": 0,
"codec_name": "h264",
"codec_long_name": "H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10",
"profile": "High",
...
}
}
]
}
**/
})
.catch(function (err) {
console.error(err);
})
});
```
## API
### `ffprobe(mediaFilePath, opts, [cb])`
* `mediaFilePath` - path to your audio / video / image that you want to get media
info for.
* `opts` - options object with the following options:
* `path` - path to ffprobe binary (You can use
[`ffprobe-static`](https://github.com/joshwnj/ffprobe-static) to easily get
a static binary that you can install with npm.
* `cb(err, info)` - standard callback, with the info returned as a javascript
object. NB: If the `cb` parameter is not provided, a `Promise` will be returned
allowing chained `then()`, `catch()` methods.
