AnalyzeBitmap function in QR code detection #25

Open mun24 opened 8 years ago

mun24 commented 8 years ago

My issue is similar to this issue. https://github.com/mmaitre314/VideoEffect/issues/13

I am getting access violation when I try to navigate away from scan page which has this AnalyzeBitmap function which is given as third parameter to function LumiaAnalyzerDefinition as shown below line.

var definition = new LumiaAnalyzerDefinition(ColorMode.Yuv420Sp, 640, AnalyzeBitmap);

I noticed that AnalyzeBitmap is repeatedly getting called. How can this be stopped if required.

Thanks.

Either disposing MediaCapture or calling ClearEffectsAsync() should stop the calls.

For the crash, if you can get a callstack in the native debugger that might give more info about what is happening.
