## <a name="tipsandtricks">Tips & Tricks</a>
|
||||||
|
|
||||||
|
A growing collection of tips & tricks to improve the various aspects of Quagga.
|
||||||
|
|
||||||
|
### Barcodes too small?
|
||||||
|
|
||||||
|
Barcodes too far away from the camera, or a lens too close to the object
|
||||||
|
result in poor recognition rates and Quagga might respond with a lot of
|
||||||
|
false-positives.
|
||||||
|
|
||||||
|
Starting in Chrome 59 you can now make use of `capabilities` and directly
|
||||||
|
control the zoom of the camera. Head over to the
|
||||||
|
[web-cam demo](https://serratus.github.io/quaggaJS/examples/live_w_locator.html)
|
||||||
|
and check out the __Zoom__ feature.
|
||||||
|
|
||||||
|
You can read more about those `capabilities` in
|
||||||
|
[Let's light a torch and explore MediaStreamTrack's capabilities](https://www.oberhofer.co/mediastreamtrack-and-its-capabilities)
|
||||||
|
|
||||||
|
### Video too dark?
|
||||||
|
|
||||||
|
Dark environments usually result in noisy images and therefore mess with the
|
||||||
|
recognition logic.
|
||||||
|
|
||||||
|
Since Chrome 59 you can turn on/off the __Torch__ of our device and vastly
|
||||||
|
improve the quality of the images. Head over to the
|
||||||
|
[web-cam demo](https://serratus.github.io/quaggaJS/examples/live_w_locator.html)
|
||||||
|
and check out the __Torch__ feature.

||||||
|

|
- Improvements
|
||||||
|
- added `muted` and `playsinline` to `<video/>` to make it work for Safari 11
|
||||||
|
Beta (even iOS)
|
||||||
|
- Fixes
|
||||||
|
- Fixed [example/live_w_locator.js](https://github.com/serratus/quaggaJS/blob/master/example/live_w_locator.js)
|

### 2017-06-06
|
||||||
|
- Features
|
||||||
|
- Support for Standard 2of5 barcodes (See
|
||||||
|
[\#194](https://github.com/serratus/quaggaJS/issues/194))
|
||||||
|
- Support for Code 93 barcodes (See
|
||||||
|
[\#194](https://github.com/serratus/quaggaJS/issues/195))
|
||||||
|
- Exposing `Quagga.CameraAccess.getActiveTrack()` to get access to the
|
||||||
|
currently used `MediaStreamTrack`
|
||||||
|
- Example can be viewed here: [example/live_w_locator.js](https://github.com/serratus/quaggaJS/blob/master/example/live_w_locator.js) and a [demo](https://serratus.github.io/quaggaJS/examples/live_w_locator.html)
