This will result in two files. The first will be a webm file (suitable for play in a browser) with a `title` field on the file set to "The Greatest Story Ever Hulaed". The second file will copy the first stream from each file directly, and set the language of the subtitle stream to English.
### Using FormatInterface
## What's not yet done?
It is also possible to set the codec from a stream using the [Formats](https://github.com/PHP-FFMpeg/PHP-FFMpeg/#formats) from PHP-FFMPEG.
Mostly documentation. There are a lot more ways to use this, including using the `Format` objects from PHP-FFMpeg to set the codecs, and the ability to use callbacks to set additional data on both maps and individual streams.
```php
use FFMpeg\Format\Video\X264;
MappableMedia::make($ffmpeg)
->addInput('input.mkv')
->map()
->saveAs('output.mkv')
->stream()->setCodec(new X264())->saveStream()
->saveMap()
->save()
```
### Using callbacks
The `map` and `stream` methods can take an optional callback, allowing you to set the properties on those individual objects. When a callback is passed the object itself is returned, allowing you to continue the chain.
```php
MappableMedia::make($ffmpeg)
->addInput('input.mkv')
->map(function (Map $map) {
$map->saveAs('output.mkv')
->stream(function (Stream $stream) {
$stream->copy()->setInput('0:0');
});
})->save()
```
Note that when using callbacks, you also don't need to call `saveMap()` or `saveStream()`.
### Getting progress updates
It is possible to set a listener on the individual streams, using the Format class. However, this don't reliably report the progress of a particular stream. So, this package adds a listener on the `MappableMedia` object itself, which represents the progress of the entire job.
```php
MappableMedia::make($ffmpeg)
->addInput('input.mkv')
->map()
->saveAs('output.mkv')
->stream()->copy()->saveStream()
->saveMap()
->on('progress', function (MappableMedia $media, int $percent, int $remaining, int $rate) {
echo "Finished {$percent}% of ", $media->getPathfile(), "\n";
})
->save()
```
### Attachments
Some formats (mkv, for example) support arbitrary data attachments. These can be used as cover art, fonts for subtitles, or any arbitrary data.
FFMpeg does support attachments as an additional input. This works well for images, but can be finicky for other file types. Because of this, FFMpeg also supports an `-attach` flag which can be used to explicitly attach a new stream.
Due to the way FFMpeg handles `-attach` differently than `-i`, these need to be added as streams to a specific map, rather than the whole media. Here are a few examples.
```php
MappableMedia::make($ffmpeg)
->addInput('input.mkv')
->map()
->saveAs('output.mkv')
->stream()->copy()->saveStream()
->attach('image.jpg')
->mime('image/jpeg')
->addMetadata('filename', 'cover.jpg')
->saveAttachment()
->saveMap()
->save();
```
In this example, we added cover art to the file. Notice the use of the `mime` method to specify the mime-type. **This must always be done**. Note that we also specified a different filename so that the media player would recognize it as cover art. If you don't specify a filename, the original will be used.
```php
MappableMedia::make($ffmpeg)
->addInput('input.mkv')
->addInput('subs.ass')
->map()
->saveAs('output.mkv')
->stream()->copy()->saveStream()
->stream()->setInput('1:0')->copy()->saveStream()
->attach(verdana.ttf')
->mime('application/x-truetype-font')
->saveAttachment()
->saveMap()
->save();
```
In this example, we've added a font, which is likely referenced in the subtitle file, `subs.ass`.
## Future Plans
- [ ] Add listeners that return all the stdin/stderr
- [ ] Support itsoffset for inputs
- [ ] Support -t and -ss
+ I need to figure out how this will affect the progress listener.
I also need to figure out how to set the listeners on the codecs to get realtime progress updates (see [Formats](https://github.com/PHP-FFMpeg/PHP-FFMpeg/#formats)). Once that's figured out, I need to document it properly here.
