Hi Isaak
First of all thank you for the great work.
I'm facing a problem with old versions of chrome and webkit based browsers on android (chrome, edge etc.).
The exception i'm getting is
Uncaught TypeError: wasm function signature contains illegal type
at /wasm-function[11]:28
at /wasm-function[63]:34
at /wasm-function[62]:7
at scanImage (zbar-wasi.esm.js:5186)
at renderLoop ((index):25)
at track ((index):70)
at HTMLVideoElement.domVideo.addEventListener ((index):62)
I was able to reproduce it by using an old version of chromium for windows 72.0.3579.0, which can be downloaded here:
I have reasons to believe that this exception is also causing #2 , since in the past I noticed a certain coherence between the behaviours of this version of chrome and iOS Safari.
This is as far as I can reach with my limited knwledge of wasm.
Could you please look into it?
Thank you again
Daniele
The video freezes after taking the first shot from camera and executing the scan via WASM. Seems to be a common issue with Safari browsers.
