processEveryNthFrame on Android no results returned

[brooklax]

@triniwiz apologies but I just tested with a new android build on my side and although I don't get an exception anymore like before, it also seems like adding the property now results in no results returned for the detection event. When I remove the property scanning works but it's not accurate with Code39 barcode types especially.

<MLKitView
cameraPosition="back"
:detectionType="type || 'all'"
:barcodeFormats="formats"
:processEveryNthFrame="60"
@detection="onScanResult"
:pause="pauseScanner"
:torchOn="torchOn"
/>

UpVote. Thanks @triniwiz. We really need a fix on this one.

@triniwiz Good day Sir, this is affecting our business quite badly, please can we give this some attention? Thanks

[triniwiz]

@devlinpadayachee are you on v2 ?

@triniwiz Devlin and work for the same company, we tried with:

"@nativescript/mlkit-barcode-scanning": "^2.0.0",
"@nativescript/mlkit-core": "2.0.0",

No difference unfortunately, when I add processEveryNthFrame on Android it doesn't trigger the @detection event.

@triniwiz anything I can do to make it easier to investigate this issue?

[triniwiz]

So only when using processEveryNthFrame it fails ?

Hi, Yes Good Sir,

On IOS processEveryNthFrame works perfectly and returns results.
When the processEveryNthFrame flag is added to Android it returns no results.

This is how we have implemented it:

<MLKitView
cameraPosition="back"
:detectionType="type || 'all'"
:barcodeFormats="formats"
:processEveryNthFrame="60"
@detection="onScanResult"
:pause="pauseScanner"
:torchOn="torchOn"
/>

@triniwiz let me know if you need a sample app to help replicate

[triniwiz]

@brooklax my tests are usually done here

hi @triniwiz , please clarify your previous message? I am offering to make a NS Vue app you could use to debug the issue?

Hello, any update on this?

I' ve got these packages and when I add the property then scanning stops working (detection) not triggering

I test on Android platform (targetSdk 34)

"@nativescript/mlkit-barcode-scanning": "^2.1.0",
    "@nativescript/mlkit-core": "^2.1.0",

"@nativescript/angular": "^18.0.0",
    "@nativescript/core": "~8.8.0"

[triniwiz]

@harfyt with 8.8 you should try

"@nativescript/mlkit-barcode-scanning": "3.0.0-alpha.3",
"@nativescript/mlkit-core": "3.0.0-alpha.3",
