## UPC-A vs EAN-13 codes
UPC-A is a special case to handle if you need to cater for it. Android's SDK officially supports UPC-A but iOS does not, instead they handle the code as EAN-13. Since EAN-13 is a superset of UPC-A, with an extra 0 digit at the front.
This means, the `upc-a` types are reported under the `ean-13` umbrella type on iOS:
```jsx
const codeScanner = useCodeScanner({
codeTypes: ['upc-a'], // <-- ✅ We configure for 'upc-a' types
onCodeScanned: (codes) => {
for (const code of codes) {
console.log(code.type); // <-- ❌ On iOS, we receive 'ean-13'
}
}
})
```
You will need to keep this in mind and do the conversion from EAN-13 to UPC-A yourself. This can be done by removing the front `0` digit from the code to get a UPC-A code.

* 4k Photos, 1080p Videos, 240 FPS (ultra high FPS/slow motion)
* 720p Photos, 720p Videos, 30 FPS (smaller buffers/e.g. faster face detection)
* Each app has different requirements, so the format filtering is up to you.
* The `videoResolution` and `videoAspectRatio` options also affect the preview, as preview is also running in the video stream.
To get all available formats, simply use the `CameraDevice`'s [`formats` property](/docs/api/interfaces/CameraDevice#formats). These are a [CameraFormat's](/docs/api/interfaces/CameraDeviceFormat) props:
- [`photoHeight`](/docs/api/interfaces/CameraDeviceFormat#photoheight)/[`photoWidth`](/docs/api/interfaces/CameraDeviceFormat#photoWidth): The resolution that will be used for taking photos. Choose a format with your desired resolution.
- [`videoHeight`](/docs/api/interfaces/CameraDeviceFormat#videoheight)/[`videoWidth`](/docs/api/interfaces/CameraDeviceFormat#videoWidth): The resolution that will be used for recording videos and streaming into frame processors. This also affects the preview's aspect ratio. Choose a format with your desired resolution.
- [`minFps`](/docs/api/interfaces/CameraDeviceFormat#minfps)/[`maxFps`](/docs/api/interfaces/CameraDeviceFormat#maxfps): A range of possible values for the `fps` property. For example, if your format has `minFps: 1` and `maxFps: 60`, you can either use `fps={30}`, `fps={60}` or any other value in between for recording videos and streaming into frame processors.
- [`videoHeight`](/docs/api/interfaces/CameraDeviceFormat#videoheight)/[`videoWidth`](/docs/api/interfaces/CameraDeviceFormat#videoWidth): The resolution that will be used for recording videos. Choose a format with your desired resolution.
- [`minFps`](/docs/api/interfaces/CameraDeviceFormat#minfps)/[`maxFps`](/docs/api/interfaces/CameraDeviceFormat#maxfps): A range of possible values for the `fps` property. For example, if your format has `minFps: 1` and `maxFps: 60`, you can either use `fps={30}`, `fps={60}` or any other value in between for recording videos.
- [`videoStabilizationModes`](/docs/api/interfaces/CameraDeviceFormat#videostabilizationmodes): All supported Video Stabilization Modes, digital and optical. If this specific format contains your desired [`VideoStabilizationMode`](/docs/api/#videostabilizationmode), you can pass it to your `<Camera>` via the [`videoStabilizationMode` property](/docs/api/interfaces/CameraProps#videoStabilizationMode).
- [`pixelFormats`](/docs/api/interfaces/CameraDeviceFormat#pixelformats): All supported Pixel Formats. If this specific format contains your desired [`PixelFormat`](/docs/api/#PixelFormat), you can pass it to your `<Camera>` via the [`pixelFormat` property](/docs/api/interfaces/CameraProps#pixelFormat).
- [`supportsVideoHdr`](/docs/api/interfaces/CameraDeviceFormat#supportsvideohdr): Whether this specific format supports true 10-bit HDR for video capture. If this is `true`, you can enable `videoHdr` on your `<Camera>`.

Note: When not using a `frameProcessor`, buffer compression is automatically enabled.
### GPU buffers
Enable GPU Buffer flags ([`enableGpuBuffers`](/docs/api/interfaces/CameraProps#enablegpubuffers)) to optimize the Video Pipeline for zero-copy buffer forwarding.
If this is enabled, the Video Pipeline can avoid an additional CPU -> GPU copy, resulting in better performance and more efficiency.
Note: This only takes effect when using a `frameProcessor`.
### Video Stabilization
Video Stabilization requires additional overhead to start the algorithm, so disabling [`videoStabilizationMode`](/docs/api/interfaces/CameraProps#videostabilizationmode) can significantly speed up the Camera initialization time.

2. If a camera device is not being returned by [`Camera.getAvailableCameraDevices()`](/docs/api/classes/Camera#getavailablecameradevices), make sure it is a Camera2 compatible device. See [this section in the Android docs](https://developer.android.com/reference/android/hardware/camera2/CameraDevice#reprocessing) for more information.
3. If your Frame Processor is not running, make sure you check the native Android Studio/Logcat logs. There is useful information about the Frame Processor Runtime that will tell you if something goes wrong.
4. If your Frame Processor is not running, make sure you are not using a remote JS debugger such as Google Chrome, since those don't work with JSI.
